otype: The trait that is visible to an outside observer.
O Dimples are indentations in your face as you smile. Use a Punnett square to determine the outcome of a cross
between
a heterozygous dad (Dd) and a homozygous recessive (dd) mom. Answer the questions in the box
below.
:D=Dimples d = no dimples
Possible genotypes of offspring:
Possible phenotypes of offspring:
What percentage of the offspring might have dimples?
What percentage of the offspring might NOT have dimples?
