When a gene exists in more than one form, the different forms are called
Heterozygous
Complementary genes
Genotypes
Alleles
$A$ : Test cross is the tool for knowing linkage between genes.
$R$ : Monohybrid test cross gives two phenotypes and two genotypes.
Definitions / Explanation : Filial progeny/F1 generation
If enough crosses are made between male flies of the genotype $'Aa'$ and the female flies of the genotype $'aa'$ to produce about $1000$ offsprings. Which one of the following is the most likely distribution of genotypes in the offsprings
Mendel’s law of independent assortment is applicable for
In hybridization, $Tt × tt$ give rise to the progeny of ratio
