If a cross is made between $AA$ and $aa$, the nature of ${F_1}$ progeny will be
Genotypically $AA$, phenotypically $a$
Genotypically $Aa$, phyenotypically $a$
Genotypically $Aa$, phyenotypically $A$
Genotypically $aa$, phyenotypically $A$
Using a Punnett square, work out 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 cross in which an organism showing a dominant phenotype is crossed with the recessive parent in order to know its genotype is called
Organisms phenotypically similar but genotypically different are said to be
Punnet square is a representation to calculate
The alleles are
