Answer:
A Punnett square is a tool used to predict the possible outcomes of a genetic cross, it can be represented as a grid with the alleles (genes) of one parent along the top and the alleles of the other parent along the side.
When the cross is between two homozygous dominant individuals (Ss x Ss) the Punnett square would look like this:
Step-by-step explanation:
| S | s
---|---|---
S | Ss | Ss
s | Ss | ss
Each box in the square represents a possible combination of alleles that could result from the cross, and the resulting genotype of the offspring. In this case, all of the possible combinations are SS, which is homozygous dominant. This means that all of the offspring will have the dominant allele (S) and will have the same phenotype (expression of the trait) as the parents.
