Question

Match List-I with List-II:

List-I
A. Two or more alternative forms of a gene
B. Cross of F1 progeny with homozygous recessive parent
C. Cross of F1 progeny with any of the parents
D. Number of chromosome sets in plant

List-II
I. Back Cross
II. Ploidy
III. Allele
IV. Test cross

Accepted Answer

:
- Allele (A-III): Genes which code for a pair of contrasting traits are known as alleles, i.e., they are slightly different forms of the same gene .
- Test Cross (B-IV): A cross between an organism showing a dominant phenotype (like an F1 hybrid) and the homozygous recessive parent is called a test cross .
- Back Cross (C-I): By definition, crossing the F1 progeny back to one of the parents is a back cross. A test cross is a specific type of back cross.
- Ploidy (D-II): Refers to the number of sets of chromosomes. For example, polyploidy is described as an increase in a whole set of chromosomes .
