The manx mutation, which produces no tail in cats, is a recessive lethal. what phenotype ratios would be expected from a cross between two manx cats? a. ¾ manx: ¼ normalb. ¾ normal: ¼ manxc. ⅔ manx : ⅓ normald. all manx

D

Explanation:

As both parents are Manx cats, their genotypes would be rr. Performing a cross, we know that all the resulting offspring can only have one possible genotype, which is rr, making them Manx cats as well. Hence, all their offspring would be Manx cats.
