NEET BIOLOGY

Detailed explanation-1: -Single cross hybrids result from the cross between two true-breeding organisms which produces an F1 hybrid (first filial generation).

Detailed explanation-2: -What does it mean? Answer: “F1 hybrid” is the term used for the first generation hybrid seed/plant that occurs following the successful cross-pollination of one genetically uniform plant variety with another specific genetically uniform variety.

Detailed explanation-3: -If heterozygous parents are being crossed, there is a possibility of having both, dominant and recessive, traits appearing in F1 generation. Each heterozygous parent will produce two types of gametes, one with dominant and one with a recessive allele. When these gametes fuse, they give rise to all three combinations.

Detailed explanation-4: -Every member of the F1 generation is heterozygous, the resultant offsprings produced are heterozygous having two different alleles each.
