- It must be complete without any grammatical issues.
- Have at least one question with it.

Make sure to add one X-linked problem as a reply. Make sure to include the following: A type of rat has the gene for black bands or rings on its tail. The gene loci is on the x chromosome. The banding is result of a recessive factor. Non-banded tail is dominant. What would the chance of having black banded tail male offspring be if the mother and father were both carriers or heterozygous?

In a type of lizard, eye color is a sex linked trait. Brown eyes are dominant to red. If a male with red eyes is crossed with a female that has brown eyes and is a carrier for the red eye trait, what percent of their offspring would have red eyes?

The mother has attached ear lobs and the father has detached ear lobs. Attached ear lobs are represented by X^E and detached ear lobs are represented by X^e. What would be the percent of a child getting detached ear lobs if the mother is heterozygous and the male has detached ear lobs? What percent of the males would have attached ear lobs?

Normal eyesight is dominant to color blindness.The gene loci is on the X chromosome. If you cross a mother that is heterozygous with a male that has normal eyesight, what percent of the children will be color blind? What percent of the females will be colorblind?

In humans, eye color is a sex linked trait. Blue eyes are dominant to green. (Blue-XB Green-Xb) What would be the cross of a heterozygous female and a blue eyed male? If they have 4 children, what percent would have blue eyes? What percent would have green eyes?
