Question

what gene combination will have 50% chance of occurring if two heterozygous black and chickens are mated 
please answer!!

Answer 1

It will be the one with capital and lowercase for example you will get (using Hh alleles for example)

(HH, Hh, Hh, hh)

So it will be the 2nd and 3rd combo, the heterozygous dominant it will have one dominant allele and one recessive
