Choose the CORRECT sequential of the following terms and fill up the blanks.

(I) The ability of a gene to have multiple phenotypic effect is called.........

(II)......... are those non-allelic genes, which not only are able to produce their own effects independently when present on dominant state but can also interact to form a new trait.

(III)........are non-allelic genes which independently show a similar effect but produce a new trait when present together in dominant form.

(iv) The phenomenon where none of the contrasting factors (alleles) is dominant and the expression of the trait in Fi is intermediate expression of the two factors is .........

APleiotropy, Supplementary genes, Complementary genes, Incomplete dominance

BMultiple allelism, Supplementary genes, Complementary genes, Epistasis

CMultiple allelism, Complementary genes, Supplementary genes, Pleiotropy

DEpistasis, Complementary genes, Supplementary genes, Pleiotropy

Answer:

A. Pleiotropy, Supplementary genes, Complementary genes, Incomplete dominance

Read Explanation:

  • Pleiotropy is a type of genetic expression in which only one gene affects multiple traits.

  • Supplementary genes are genes that contain two non-allelic pairs of genes. They're both having an effect on the same character.

  • Complementary genes are a kind of gene interaction in which two genes interact to produce a specific phenotype or observable trait.

  • Incomplete dominance pertains to the genetic phenomenon in which the distinct gene products from the two codominant alleles in a heterozygote blend to form a phenotype intermediate between those of the two homozygotes.
