The crossing of ‘F1’ progeny with the homozygous recessive parent is: (RJ ACF Agriculture 2018)

✅ Explanation:A test cross involves crossing an individual with an unknown genotype with a homozygous recessive individual. This is done to determine the unknown genotype by observing the phenotypes of the offspring. If any offspring display the recessive trait, the unknown parent must carry the recessive allele.

📌Other Options Explanations:

✏️Option A: Back cross:
-A back cross involves crossing an offspring with one of its parents or an individual genetically similar to its parent, aiming to maintain or enhance specific traits.

✏️Option B: Dihybrid cross:
-A dihybrid cross involves crossing individuals that differ in two traits, used to study the inheritance patterns of two genes.

✏️Option C: Reciprocal cross:
-A reciprocal cross involves a pair of crosses where the sexes of the parents are reversed. For example, a tall male plant crossed with a short female plant, then a tall female crossed with a short male. This helps determine if a trait is sex-linked.
