An F₂ phenotypic ratio of 1: 4: 6: 4: 1 from a cross AaBb X AaBb is expected in the case of:

1.	Dominant epistasis	2.	Complementary genes
3.	Polygenic inheritance	4.	Independent assortment

The mode of inheritance of the trait shown in the following pedigree is most likely:

A dihybrid test cross results in a recombination frequency of 50%. Most likely the two genes under consideration:

The number of linkage groups in a plant with a normal diploid number of chromosomes in a somatic cell as 16 will be:
1. 16
2. 8
3. 4
4. It is impossible to tell from the information provided.

In the pedigree shown, mating between individuals III 2 and III 3 results in a progeny, which is an affected female. Based on this information, most likely this disorder is:
 

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?

The pedigree shows the inheritance of red-green color blindness in a family. If II 3 marries a color-blind man, what is the probability that her first child will be normal?

The source of any of the genes located on either of the X chromosomes in a female cannot be:

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?

The inheritance of the trait shown in the given pedigree most likely is:
