Question

For a type of cat, short whiskers are dominant (s) and long whiskers are recessive (s). the punnett square below shows a cross between two cats. what is the phenotype ratio for this cross?

Answer 1

Since there are a dominant and a recessive character, therefore, this is a case of Mendelian characters. There are some possibilities

1- Dominant pure SS is crossed with dominant pure SS, all the generation will be dominant.

2- Dominant Pure SS is crossed with recessive ss, aal the first generation will be dominant phenotype and impure genotype (Ss). The second generation will be 3 dominant: 1 recessive. The 3 dominant in the second generation will be 1 pure SS and two impure Ss.

3- Dominant Impure with recessive, the first generation will be 1 dominant impure : 1 recessive.

4- Recessive with recessive, the generation will be all recessive.
