Question

If a cross between two individuals produces offspring with 50% dominant character (a) and 50% recessive character (a) the genotype of parents are

Answer 1

let the genes for dominant character be T and receive character be t

50% offspring with dominant character: TT or Tt

50% offspring with recessive character: tt

this situation can only be possible if one parent is Tt and one is tt....that is a test cross.

so one parent would be heterozygous for the alleles of the gene while the other parent would be homozygous for the allele
