Answer:
we can see that we have 2 short whiskers and 2 long whiskers , so the phenotypic ratio is 2:2 which is the same as 1:1
Step-by-step explanation
the question asks for the phenotype ratio of cross between two cats.
here we are told that the allele for short whiskers is Dominant (S) and the allele for long whiskers is recessive (s). this statement means that when we cross two cats with a dominant allele S, the cat will have short whiskers and when we have the recessive alleles only, the cat will have long whiskers.
in the Punnett square below a cat with Ss and ss alleles are crossed.
when we do a cross each individual allele from one cat is cross with the two alleles of the other cat to give a total of for crosses. we can see that the offsprings will have the following genotypes
Ss
ss
Ss
ss
since we now have the genotypes of the cats, we can use the information from above about dominant and recessive alleles to determine the phenotypic ratio
Ss - short whiskers
ss - long whiskers
Ss - short whiskers
ss - long whiskers
we can see that we have 2 short whiskers and 2 long whiskers , so the phenotypic ratio is 2:2 which is the same as 1:1
