In a separate study, 68 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Sonora, Mexico. The other three were in Chihuahua, Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three Chihuahua locations were slightly darker than the dark-colored mice from the Sonora population. The entire Mc1r gene was sequenced in all 68 of the mice collected. The mutations responsible for the dark fur color in the Sonora mice were absent from the three different populations of Chihuahua mice. No Mc1r mutations were associated with dark fur color in the Chihuahua populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases.

How does this study support the  concept that natural selection is not random?  

Answer:

The study supports the  concept that natural selection is not random because in different areas with the same or very similar environmental characteristics, the same phenotype was produced by different types of mutations.  

Explanation:

All of the sampled animals are inhabiting dark substrate. Probably animals needed to camouflage to survive. Natural selection must have driven them to produce dark color, similar to the substrate color. So animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. The environmental condition is favoring the same phenotype.

Which of the following best describes how independent assortment results in inherited variations within a species and how it contributes to evolution?

A Independent assortment results from the copying of DNA during cell division and causes variations that are sometimes beneficial to a species


B Independent assortment results from the binary fission of a single cell and causes mutations that can be beneficial or harmful to a species


C Independent assortment occurs during mitosis and causes uncontrolled cell division which is harmful to a species


D Independent assortment occurs when chromosomes separate during meiosis and causes variations that can be beneficial or harmful to a species

Answers

Answer:

D Independent assortment occurs when chromosomes separate during meiosis and causes variations that can be beneficial or harmful to a species

Explanation:

During meiosis, the homologous chromosomes separate and segregate independently of each other. This process is referred to as 'independent assortment'. In consequence, different gene variants or 'alleles' localized in homologous chromosomes segregate independently of each other during gamete formation, thereby one particular gamete has an equal probability to carry either of these segregating alleles. Independent assortment generates genetic variation in the gametes, which can be beneficial or deleterious in a given environment.

The option that best describes how independent assortment results is D Independent assortment occurs when chromosomes separate during meiosis and causes variations that can be beneficial or harmful to a species

What is independent assortment ?

Independent assortment is a phenomenon that occurs during meiosis, which is the process of cell division that produces gametes (sex cells). During meiosis, the chromosomes are randomly sorted into the gametes. This means that the alleles (different forms of a gene) on different chromosomes can be inherited together or separately.

This random assortment of alleles can lead to new combinations of traits, which can be beneficial or harmful to a species.

Eye color in a particular strain of fly is influenced by one gene with two alleles: a dominant allele that results in red eyes and a recessive allele that results in sepia eyes. A red-eyed female from a true-breeding population is mated with a sepia-eyed male. The Fl offspring are all red-eyed. The Fl flies are allowed to interbreed, producing the following in the F2 generation.
Females: 40 red eyes; 13 sepia eyes
Males: 39 red eyes; 11 sepia eyes
Which of the following best describes the likely mode of inheritance for the eye-color gene?
a. The eye-color gene is likely autosomal because males and females have similar phenotype ratios.
b. The eye-color gene is likely autosomal because more females have sepia eyes than males do.
c. The eye-color gene is likely sex-linked because the males and females have similar phenotype ratios.
d. The eye-color gene is likely sex-linked because the males and females display both phenotypes.

Answers

Answer:

The correct option is a. The eye-color gene is likely autosomal because males and females have similar phenotype ratios.

Explanation:

Available data:

Eye color is influenced by a diallelic gene R dominant allele results in red eyesr recessive allele results in sepia eyesCross: true-breeding red-eyed female with a sepia-eyed maleF1: 100% red-eyed.F2: Females: 40 red eyes; 13 sepia eyes

              Males: 39 red eyes; 11 sepia eyes

77% of the total progeny has red eyes and 23% has sepia eyes.

Among females, 75% is red-eyed, and 25% is sepia-eyed

Among males, 78% is red-eyed, and 22% is sepia-eyed.

The general phenotypic ratio is 3:1

If the eye-color gene was sex-linked, the phenotypic ratios would be different. There would be a higher proportion of red-eyed females than red-eyed males. Females would only express red eyes, while males would express red and sepia eyes. This is

Cross:         X⁺X⁻   x    X⁺Y        (Note: The symbol + represents the allele R

Phenotype: red-eyed both                    and the symbol  - the allele r)                  

Gametes) X⁺       X⁻     X⁺    Y

Punnett square)    X⁺         X⁻

                      X⁺   X⁺X⁺     X⁺X⁻

                       Y    X⁺Y       X⁻Y

F2) 3/4 of the whole progeny would be red-eyed

     1/4 of the whole progeny would be sepia-eyed

  BUT

     Females: 100% red-eyed

     Males: 50% red-eyed and 50% sepia-eyed

These proportions are not coincident with the exposed real proportions

So,

c. The eye-color gene is likely sex-linked because the males and females have similar phenotype ratios.

If this gene was sex-linked, Males and females would not have similar phenotype ratios. This is FALSE.

d. The eye-color gene is likely sex-linked because the males and females display both phenotypes.

If this gene was sex-linked, Males would display both phenotypes, but females would only be red-eyed. This is also FALSE.

According to this, we can assume that this is an autosomal gene. If this is true, then

Cross:   Rr XX    x    Rr XY

Gametes) RX, RX, rX, rX

                RX, RY, rX, rY

Punnett square:

              RX       RX       rX       rX

RX      RRXX    RRXX   RrXX   RrXX

rX       RrXX      RrXX    rrXX    rrXX

RY      RRXY     RRXY   RrXY   RrXY

rY       RrXY      RrXY    rrXY    rrXY

F2)  From the whole progeny

      12/16 = 3/4 = 75% would be red-eyed       4/16 = 1/4 = 25% would be sepia-eyed

       Phenotypic ratio 3:1

       Among females

       6/8 = 3/4 = 75% would be red-eyed, R-XX        2/8 = 1/4 = 25% would be sepia-eyed, rrXX

        Phenotypic ratio 3:1

      Among males

       6/8 = 3/4 = 75% would be red-eyed, R-XY        2/8 = 1/4 = 25% would be sepia-eyed, rrXY

       Phenotypic ratio 3:1

The phenotypic ratio in all cases are 3:1.

b. The eye-color gene is likely autosomal because more females have sepia eyes than males do.

Both males and females exhibit sepia eyes in equal proportions. This is FALSE

a. The eye-color gene is likely autosomal because males and females have similar phenotype ratios.

Males and females do have similar phenotype proportions of red eyes and sepia eyes. This is TRUE

Hybrid
Corn
h
Short Height: 0%

Answers

Answer:

See the answer below

Explanation:

Normal height - H

Short height - h

Heterozygous - Hh

A cross involving heterozygotes would be Hh x Hh

         Hh    x    Hh

      HH   Hh   Hh   hh

Since H is dominant over h;

HH and Hh would produce normal height phenotypes.

hh will produce a short height phenotype.

Thus;

Probability of normal height phenotype resulting from the cross = 3/4 or 75%

Probability of short height phenotype resulting from the cross = 1/4 or 25%

In quiet breathing, muscular effort is used mainly in inspiration, and expiration is largely passive, due to elastic recoil of the lung. It results in a pattern change between expiratory and inspiratory flow. Explain changes you observed in the recordings you obtained. 1 pts Enter your answer here

Answers

Answer:

During quiet breathing, the main muscular effort is made in the inhalation process and the expiration process is mainly passive as it depends on the inhalation.

The expiration occurs due to the elastic recoil that causes a decrease in volume. In this process, the contraction of the diaphragm helps in the inhalation which is least affected by the intercostal muscle. During quiet breathing, the rate of inhalation and expiration time is relatively proportionate to one another.

During this, the contraction of the diaphragm helps in the inhalation which is least affected by the intercostal muscle whereas quiet breathing, the rate of inhalation and expiration time is relatively proportionate to one another.

What is Breathing?

Breathing is the process of moving air into and from the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen.
