Freida’s claim is accurate only under certain conditions.
<u>Explanation:</u>
Freida claims that she can determine which sex chromosome was donated by the male parent and which was donated by the female parent. This claim cannot always be valid. A female parent has homozygous sex chromosomes. Both the sex chromosomes of a female is X.
A male has one X chromosome and one Y chromosome. In reproduction a female parent always donates an X chromosome. A male parent may donate either an X or a Y chromosome. This determines the sex if the child.
If an X chromosome is donated the child will be girl with the genotype XX and if the Y chromosome is donated the child will be boy with genotype XY. Thus only in the case the child is a boy can we correctly determine which sex chromosome was denoted by the male parent and female parent.
If the child is a girl with both X chromosomes we cannot determine which X chromosome was donated by father and which was donated by mother because both are X.
