Question

Multiple phenotype is seen in _______________.
  1. Dominance relationship
  2. Particulate inheritance
  3. Monogenic inheritance
  4. Polygenic inheritance.

A
Polygenic inheritance.
B
Dominance relationship
C
Particulate inheritance
D
Monogenic inheritance
Solution
Verified by Toppr

A.Dominance relationship - a relationship between alleles of one gene, in which the effect on phenotype of one allele masks the contribution of a second allele at the same locus. The first allele is dominant and the second allele is recessive.

B.Particulate inheritance - the inheritance of discrete characters via genes that are independently expressed without the blending of characters from one generation to the next generation.

C.Monogenic inheritance – inheritance, involves the transfer of a character by the involvement of a single gene. It produces only one type of phenotypes.

D.Polygenic inheritance - inheritance, involves the transfer of a character by the involvement of a more than one gene. It produces multiple phenotypes.

So, the correct option is ‘Polygenic inheritance’.
