According to Hardy Weinberg principle.
p² + 2pq + q² = 1; (p + q)² = 1
(AA) p² = 360 out of 1000 individual or p² = 36 out of 100.
q² = 160 out of 1000 or q² = 16 out of 100
so q = √.16 = .4, As p + q = 1
so p is 0.6.

Correct Option: C

ABO blood group system in human beings is an example of codominant, dominant recessive and multiple alletes. Blood groups are controlled by the gene I located on 9^th chromosome that has 3 multiple alleles, out of which any two are found in a person. In codominance both gene express it self completely.

Correct Option: D

In Co-dominance F₁ generation resemble both the parents. Ex: Blood group inheritance.

Correct Option: C

In Co-dominance F₁ generation resemble both the parents. Ex: Blood group inheritance.

Tightly linked genes show more linkage then crossing over.

Correct Option: A

Tightly linked genes show more linkage then crossing over.

Incomplete (partial or mosaic) dominance is the phenomenon where none of the two contrasting alleles or factors is dominant. The expression of the character in a hybrid or F₁ individual is intermediate or a fine mixture of the expression of the two factors (as found in homozygous state). Incomplete or mosaic inheritance is not an example of premendelian concept of blending inheritance because the parental types reappear in the F₂ generation. It is however, considered by some workers to be an example of quantitative inheritance where only a single gene pair is involved. F₂ phenotypic ratio is 1: 2: 1, similar to genotypic ratio.
