Dimples (D) are dominant to not having dimples. Two parents (who both have dimples) have 4 kids; 3/4 kids have dimples and 1/4 does not have dimples. What are the parents' genotypes?
Purple flowers and tall stems = 4/16
It has the nitrogen base uracil
Parent 1 is homozygous dominant and parent 2 is homozygous recessive
white flower, tall stem
