Question

An organism has two unlinked genes X and Y. Its
gentotype is XxYy. Which of the following genotypes is
possible in a gamete from this organism?
(a) XX
(b) XxYy
(c) Xy
(d) Yy​

Answer 1

Answer:

b

Explanation:

XxYy according to me plz tell if I am wrong

Answer 2

Xy genotypes is possible in a gamete from this organism. So otion C is correct choice.

In the genotype XxYy, X and Y are unrelated genes that are spread across different chromosomes. Each chromosome segregates autonomously into several gametes during gamete development. Hence, the following gametes may be generated from this organism:

Xy: This gamete has one copy of each of the X and Y genes.

XY: The X and Y genes are each present in one copy in this gamete.

xY: The x and Y genes are each present in one copy in this gamete.

xy: The x and Y genes are each present in one copy in this gamete.

Consequently, option (c), Xy, which is a potential gamete from this creature, is the proper response. Due to the fact that they do not depict the separate segregation of the X and Y genes during gamete formation, options (a) XX, (b) XxYy, and (d) Yy are not viable gametes.
