Question

When Bridges crossed a particular white-eyed female with a red-eyed male, unexpectedly 5% of females has white eyes. What phenomenon explains these rare events?

Answer 1

The phenomenon that explains the rare event of 5% of females having white eyes is called sex-linked inheritance.

Step-by-step explanation:

The phenomenon that explains the rare event of 5% of females having white eyes when crossing a particular white-eyed female with a red-eyed male is called sex-linked inheritance.

In this case, the gene for eye color is located on the sex chromosome. The white-eyed trait is recessive and located on the X chromosome, while the red-eyed trait is dominant.

When a white-eyed male is crossed with a heterozygous female, the resulting offspring will have a ratio of 50% males with red eyes, 50% males with white eyes, 50% females with red eyes, and 50% females with white eyes. This is because the white-eyed trait is only located on the X chromosome, so males have a higher chance of inheriting it.
