Options

A. `{:("A","B","C","D"),(2,3,4,1):}`
B. `{:("A","B","C","D"),(4,1,2,3):}`
C. `{:("A","B","C","D"),(4,3,1,2):}`
D. `{:("A","B","C","D"),(2,1,4,3):}`

Answer

A

Explanation

Dominance-Expression of only one allele in a heterozygous organism.
Codominance-Side by side full expression of both alleles. `F_(1)` resembles both parents.
Pleiotropy - Single gene can exhibit multiple phenotypic expression, e.g.,Phenylketonuria.
Polygenic inheritance-Many genes govern a single character, e.g. Human skin colour.
