Understanding Progeny Probabilities in Genetic Mating

What are the correct probabilities regarding the progeny of a mating of an Ss RR individual to an individual who is Ss Rr?

A) 25% Ss RR, 50% Ss Rr, 25% ss RR

B) 50% Ss RR, 25% Ss Rr, 25% ss RR (Correct)

C) 25% Ss RR, 25% Ss Rr, 50% ss RR

D) 25% Ss RR, 75% Ss Rr, 0% ss RR

Correct Probabilities of Progeny in the Genetic Mating

The correct probabilities regarding the progeny of a mating between an Ss RR individual and an individual who is Ss Rr are 25% Ss RR, 50% Ss Rr, and 25% ss RR.

When determining the probabilities of different genotypes in the progeny of a genetic mating, a Punnett square can be used. In this case, where an Ss RR individual mates with an individual who is Ss Rr, the Punnett square would show the following probabilities:

25% of the progeny will have the genotype Ss RR

50% of the progeny will have the genotype Ss Rr

25% of the progeny will have the genotype ss RR

Therefore, the correct probabilities of the progeny in this mating scenario are 25% Ss RR, 50% Ss Rr, and 25% ss RR. Understanding genetic probabilities in mating of individuals with specific genotypes is key to predicting the outcomes of genetic crosses.
