Answer 1

A - III, B - IV, C - I, D - II

Explanation:

List-I	List-II
A. Two or more alternative forms of a gene	III. Allele
B. Cross of F1 progeny with homozygous recessive parent	IV. Test cross
C. Cross of F1 progeny with any of the parents	I. Back cross
D. Number of chromosome sets in plant	II. Ploidy

Alleles are distinct variations of a gene in the field of genetics. In a test cross, an organism’s genotype is ascertained by crossing it with a homozygous recessive parent. A back cross occurs when a F₁ individual crosses with one of its parent lines. The number of chromosomal sets in a cell or organism is referred to as ploidy.
