In fruit flies (Drosophila melanogaster) there is a dominant allele for red eyes and a recessive allele for white eyes. These al

leles are located on the X chromosome. If a heterozygous red-eyed female is mated with a white-eyed male, what percentage of the offspring are expected to be white-eyed females?

Answer:

50% of the offspring female population are expected to be white eyed females

Explanation:

Since the allele can only be found on the X chromosome, the chances of the offspring developing white eyes, would mostly occur in the females; since the heterozygous female would mate with a white eyed male.

This results to the following below

R- red eyes

w- white eyes

Female - R w            X             Male- w w

Offspring alleles F1-   R w   R w   w w   w w

Therefore, from the cross, we can conclude that the percentage possibility of white eyed females is... 50%.

Pancreatic cells, which secrete a large amount of digestive enzymes, are labeled with radioactive leucine and then chased for se
LiRa [457]

Answer:

Option-C

Explanation:

A pulse-chase experiment which is used to study the cellular process taking place in the cells. This uses the labelled molecule which is incorporated into the cellular pathway and then the unlabeled molecules are used over time to determine how much time is required by the unlabeled molecule to replace the labelled molecule.

In the given question, the pancreatic cell which secretes the digestive enzyme known as the acinar cell is labelled with the leucine and then used unlabeled leucine.

When observed after three hours, the black spots will appear on the exterior of the cell as the protein has been synthesised by the ER and now has been secreted from the cell.

Thus, Option-C is the correct answer.
