The lineage of pea plants produced round seeds for four generations. The plants that fertilized these pea plants also produced round seeds. However, in the fifth generation, the plant produced to two plants with wrinkled seeds. Can that be possible? Explain your answer using your pedigree chart.
Answers
Answer:
Explanation:
This happened because two fully recessive plants where introduced into the lineage. these plants where paired with the dominate verison. this would make all of the offspring have the two traits. this being said it would make it possible for the offspring to be Wrinkled Seeds.
When two heter0zyg0us individuals are crossed -simple d0minant inheritance-, or a heter0zyg0us individual is crossed with a h0m0zyg0us recessive one, they can produce h0m0zyg0us recessive subjects among the progeny. Heter0zyg0us individuals among the fourth generation got crossed with another plant (h0m0zyg0us recessive or heter0zyg0us) and produced two h0m0zyg0us recessive plants expressing wrinkle seeds.
---------------------------
The first step is to understand the given information. So,
The first four generations produced round seedsPlants that fertilized these plants also produced round seeds (see generation II) Among the fifth generation there are two plants with wrinkled seedsLet us assume that a diallelic gene determines the shape of seeds.
D0minant allele R codes for round seedsRecessive allele r codes for wrinkle seedsNow, let us analyze the pedigree. According to the information provided here, we can tell that
black figures represent h0m0zyg0us d0minant individuals, grey figures represent heter0zyg0us individualsempty figures represent h0m0zyg0us recessive individualsRemember that Generations are represented with roman numbers.
We will name the plants with numbers from 1 to 26.
According to the information in the statement and the information in the pedigree, we can say that grey individuals from the fourth generation are heter0zyg0us expressing round seeds. They can produce wrinkle seeds, if they are fertilized by another heter0zyg0us plant or a h0m0zygous recessive one.
Option 1:
Two heter0zyg0us plants are crossed, and their offspring have wrinkled seeds.
Option 2:
One heter0zyg0us plant is crossed with a h0m0zyg0us recessive one, and their offspring have wrinkled seeds. Let us see the cross

Cholera toxin locks the Gs subunit into an active state, in that GTP is bound and cannot be hydrolyzed back to GDP to turn off the subunit. What effect will cholera toxin have in the cell
Answers
Cholera toxin locks the G-subunit into an active state, in that GTP is bound and cannot be hydrolyzed back to GDP to turn off the subunit. This leads to a subsequent activation and increase in adenylate cyclase inside the cell. This increases the level of cAMP which leads to cytolysis of the cell.
The cholera toxin is released from a bacteria known as vibrio cholera. This bacteria is gram-negative and releases this toxin into the body which leads to manifestations like vomiting, increased heartbeat, watery diarrhea, cramps in the muscles and a low blood pressure. When this toxin is released into the body. The toxin activates adenylate cyclase and increases its level. This in turn increases the level of cAMP.
