The weight of the fruit of one variety of squashes is
determined by three pairs of genes: AABBCC produces 6 lb
squashes and aabbcc produces 3 lb squashes. Each dominant
allele adds 1/2 lb tothe base weight (3 lb). If a pure
breeding line that produced 6 lb squashes was crossed with
a pure breeding line that produced 3 lb squashes, what
would be the phenotypic ratio of the F1 and the F2?

7) Diabetes is recessive. A) If woman has diabetes and marries a man that doesn’t have it, is it possible for their offspring to acquire this disease? A A Aa Aa Aa Aa a a genotypes Phenotype 100% Aa, Heterozygous 100% No diabetes B) If none of the father’s ancestors had ever had diabetes, would their children have a chage of getting the disease? Explain
Consider two linked autosomal genes. The dominant allele C of the first gene causes cataracts of the eye, whereas its recessive allele produces normal eyes. The dominant allele P causes polydactyly (an extra finger) whereas its allele (p) produces a normal number of fingers. A man with cataracts and normal fingers marries a woman with polydactyly and normal eyes. Their son has both polydactyly and cataracts and he marries a woman with neither trait. What is the probability that their first child will have cataracts and polydactyly?
Cystic fibrosis (CF) occurs with a frequency of about 1/2500 Caucasian newborns and is inherited as an autosomal recessive. A woman had an older sister die from complications of this disease. CF is not present among relatives of her husband. Both the woman and her husband have normal phenotypes. What is the chance this couple will have a CF child

Flower position, stem length, and seed shape were three traits that were studied by Mendel. Each is controlled by an independently assorting gene. If a plant that is heterozygous for all three traits was allowed to self- fertilize, what proportion of the offspring would be expected to show all three dominant phenotypes?
