If S is a dominant allele and s is a recessive allele, what is the interpretation of the second generation offspring when Ss is crossed with Ss?

by Sadha Satya Lotan

What i mean with the word 'interpretation' here is something like, SS 50%, ss 25% and Ss 25%.

Normally, I find this question if the parent's genotypes are SS and ss, so both of them are homozygous and will result in only 1 type of genotype, which is Ss, and the 2nd generation offspring will be as simple as Ss crossed with Ss.

However, if there are more than 1 type of genotype in the 1st offspring, I don't know how to continue it to the 2nd generation.

For example, in the crossing between Ss and Ss, it will result SS : Ss : ss = 1 : 2 :1, I don't know how I should continue it to get the 2nd generation offspring.


Thank you
