Let us assume that the genotype for curved horns is C (dominant) and spiral horns is c (recessive).
Finding the mare's genotype,
Parents: CC x cc
F1 Generation (Mare): Cc, Cc, Cc, Cc (After meiosis.)
It can be seen that all the 4 mares in the F1 generation are hybrid (heterozygous) with curved horns, since the recessive gene doesn't express itself because of the heterozygous genotypes.
Since all four offspring have a heterozygous genotype, proportion of the offspring having a heterozygous genotype = 4/4 = 100%.
Since none of the offspring have a homozygous genotype, proportion = 0/4 = 0%.
Proportion of the offspring that will have a curved horn phenotype = 4/4 = 100%
Proportion of the offspring that will have a spiral horn phenotype = 0/4 = 0%.
Hope this helps ya.
What are 3 characteristics of bacteria?
Answer:
:')
Explanation:
lack of membrane-bound organelles, unicellular and small size.
Answer:
There are three notable common traits of bacteria, 1) lack of membrane-bound organelles, 2) unicellular and 3) small (usually microscopic) size. Not all prokaryotes are bacteria, some are archaea, which although they share common physicals features to bacteria, are ancestrally different from bacteria.

True or False: The Calvin cycle is also known as the “light-dependent reaction” because it needs sunlight.
Answer:
false
Explanation: The Calvin Cycle, or light independent reaction, does not utilize sunlight as an input. During the light independent reaction, or the Calvin Cycle, carbon fixation first occurs. CO2 produced during the light dependent reaction reacts with RuBP, ultimately producing PGA.

Biotechnology: Genetic Modification Technologies
What are three ways that genetic engineering is being used with animals? Give an example of each.
Answer: Genetic engineering is being used with animals in various ways.
Explanation:
Disease Research and Biomedical Applications: Genetic engineering enables the creation of animal models with specific genetic modifications to study diseases and develop potential treatments. For instance, scientists have created genetically modified mice that carry mutations associated with human diseases like cancer or Alzheimer's.
Agricultural and Livestock Improvement: Genetic engineering is employed in agriculture to enhance traits in livestock and improve agricultural productivity. For example, researchers have developed genetically modified pigs that are more resistant to specific diseases, such as Porcine Reproductive and Respiratory Syndrome (PRRS).
Conservation and Species Preservation: Genetic engineering has the potential to contribute to conservation efforts and species preservation. One example is the use of assisted reproductive technologies, such as in vitro fertilization (IVF) and embryo transfer, to help save endangered species.

How does the pacific ocean help explain the weather differences between San Francisco and Kansas city? If possible, discuss your answer.
The presence of pacific ocean causes weather differences between San Francisco and Kansas city.
The pacific ocean helps in explaining the weather differences between San Francisco and Kansas city because San Francisco is located near the pacific ocean which has great effect on its climate while on the other hand, Kansas city is located far from the pacific ocean which have less or no effect on the climate of the Kansas city.
San Francisco has hot, dry summers and cool, rainy winters due to presence near the pacific ocean whereas the climate of Kansas City has cold winters and hot summers with frequent thunderstorms so we can conclude that the presence of pacific ocean causes weather differences between San Francisco and Kansas city.
