How many gametes will form in a tri hybrid cross of heterozygous parents?

Question

Answer

With three unlinked genes , each parent can produce 8 difference type of gametes which generates 64 genotypic combination of the punnet square.For four unlinked markers,there are 16 possible gametes from each parent and 256 cells in the complete punnet square

Answer

No .of gamete =2^n, where n= no.ofheterozygous allel  in tri hybrid cross,n=3,so no. of gamete=2^3=8.
