Important Questions on Classical Genetics

MEDIUM

Match the following lists:

  List - I   List - II
(A) Back cross   It is the genetic make up of an individual.
(B) Test cross (II) An individual is having two different alleles for a single character. Consequently, it will produce two different types of gametes with reference to a gene.
(C) Heterozygote (III) An individual is having two similar or identical alleles for a single character. Hence, it will produce only one kind of gametes with reference to a gene.
(D) Homozygote (IV) If the F1 progeny are mated back to one of their parents.
    (V) The cross between F1 progeny (or heterozygotes) and their recessive homozygous parent.
