In the case of dalmation dogs, the non-spotted condition is recessive to the dominant spotted condition. Call the 2 alleles S for spotted and s for non-spotted. Both parents are heterozygous.
A) what are the possible genotypes of the offspring? In what ratio do they occur?
B) what are they possible phenotypes of the offspring? In what ratio do they occur ?
2) consider again the case of the dalmation dogs. Say that a spotted and a non-spotted dog are crossed. Is it possible for them to produce any non-spotted puppies? Why or why not? Explain using a punnet square
