create a punnett square crossing one person who has square palms (a) with someone who is heterozygous for palm size(Aa).
What are the genotypes(ratios)
Draw the phenotype
Please understand that biology is NOT my area!
Assuming that A is dominant and a is recessive, the mating of the two individuals (genotypes aa and Aa), would be 50% of each of the following genotypes: Aa and aa. All the children receive the recessive a from the aa parent, while half receive the dominant A from the other parent.
Unfortunately, I don't know what a square palm looks like. Have you consulted your textbook?
I hope this helps a little more. Thanks for asking.
