Question

In the X-0 system of sex determination found in some moths, the male's chromosomes are listed as __________ , whereas the female's chromosomes are listed as ____________.

Answer 1

In the X-0 system of sex determination found in some moths, the male's chromosomes are listed as X, whereas the female's chromosomes are listed as XX.

Step-by-step explanation:

In the X-0 system of sex determination found in some moths, the male's chromosomes are listed as X , whereas the female's chromosomes are listed as XX.

Sex determination in organisms can be based on the presence or absence of certain sex chromosomes. In the X-0 system, males have an X chromosome, while females have two X chromosomes. This means that males in this system are heterozygous (X0), while females are homozygous (XX).

To give an example, let's consider a specific species of moth. Suppose the male is designated by a letter, such as A, and the female is designated by another letter, such as B. In this case, a male moth would have chromosomes represented as XA and a female moth would have chromosomes represented as XXB.
