Question

Vinaya learned from her science teacher that her height probably resulted from about 180 genes, each contributing a tiny amount of genetic information. Vinaya learned that her height resulted from

A) additive genes
B) dominant genes
C) recessive genes
D) nonadditive genes

Answer 1

Answer: A) additive genes

Step-by-step explanation:

Additive genes are contribution of two of more genes to generate a single phenotype which gives combine effect of the genes .It does not have any dominant factor. Example-color of eye

According to the question, Vinaya's height is a creation of additive genes because she has got her height through equal sum collection of 180 genes .

Other options are incorrect because dominant genes ,recessive genes and non-additive genes do not create phenotype effect in which collaboration of genes have no domination or epistasis. Thus, the correct option is option(A).
