Question

What will be the distribution of phenotypic features in the first filial generation after a cross between a homozygous female and a heterozygous male for a single locus ? (A) 3: 1 (B) 1: 2: 1 (C) 1: 1 (D) None of these

F1 or first filial or progeny is the generation of hybrids produced from a cross between the genetically different individuals called parents. A cross between homozygous and heterozygous parents for a single locus will produce 1: 1 ratio of phenotypic features in F1 generation.

$3 : 1$

$1 : 2 : 1$

$1 : 1$

None of these

$F_{1}$ or first filial or progeny is the generation of hybrids produced from a cross between the genetically different individuals called parents. A cross between homozygous and heterozygous parents for a single locus will produce $1 : 1$ ratio of phenotypic features in $F_{1}$ generation.
