Question

in humans, dimples are dominant to no dimples. cross a woman with no dimples with a man who is heterozygous for dimples. determine the phenotypic and genotypic ratio of their offspring. show a punnett square to support your answer

Answer 1

Genotype: 50% Aa and 50% aa

Phenotype: 50% Dimples and 50% no dimples

Explanation: Using a punnet square, we can figure out that the mother is recessive and the father is heterozygous. Putting the mother at the top of the square and the father on the side, you end up with the results above by crossing each square with the corresponding letters. It's okay if the letters end up backwards. Just be sure to face them the right direction, capitals being first once you finish.

Hope this helps!
