Question

In foxes two alleles of a single genes p and p may result in lethality, Platinum coat,or silver coat.what ratio is obtained when platinum foxes are interbreed. Is the p allele behaving dominantly or recessively causing lethality, platinum coat colour?​

Answer 1

However, a homozygous dominant for the P gene leads to the death of the individual. The cross between two heterozygotes (platinum fox) would produce offspring according to the Punnet square shown below: From here, it can be seen that out of the 3 living outcomes, 2 would have platinum coat and 1 would be silver coated.
Hope this helps
