The inheritance of the trait shown in the given pedigree most likely is:
| 1. | Autosomal recessive | 2. | Autosomal dominant |
| 3. | Sex-linked recessive | 4. | Sex-linked dominant |
Consider three genes: X, Y, and Z. The recombination frequency between X-Y, X-Z, and Y-Z gene pairs was found to be 50%, 25%, and 50%, respectively. What would be the right inference?
| 1. | genes X and Y are on the same chromosome |
| 2. | genes X and Z are on different chromosomes |
| 3. | genes Y and Z are on different chromosomes |
| 4. | All three genes are located on the same chromosome |
The source of any of the genes located on either of the X chromosomes in a female cannot be:

In a fruit fly, the eye colour trait is located on X-chromosome and the vestigial wing trait is located on an autosome. What is the possibility that a cross between a white-eyed male fruit fly with vestigial wings and a wild-type female who is heterozygous for both traits will result in a female offspring with vestigial wings and white eyes?
| 1. | 1/16 | 2. | 1/8 |
| 3. | ¼ | 4. | ½ |
