A normal woman whose father was a hemophiliac marries a normal man. What are the chances of hemophilia occurring in their children?1 3016
In cucumbers normal leaves (N) are dominant to curled leaves (n) and elongated fruit (L) is dominant to spherical fruit and these genes are linked on the same chromosome. If a pure-breeding normal-leaved, elongated fruit cucumber is crossed with a curled-leaved, spherical fruit cucumber, what will be the phenotype of the F1? the phenotypic ratio of the F2?1110

In sesame, the one-pod condition (P) is dominant to the three-pod condition (p), and normal leaf (L) is dominant over wrinkled leaf (l). The two characters are inherited independently. Determine the genotypes and phenotypes of the two plants which produce the following progeny: 318 one- pod normal, 98 one-pod wrinkled, 323 three-pod normal and 104 three-pod wrinkled.4170

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

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?

The village of Oblong has 400 normally-shaped residents. Transferrin is an iron carrier found in blood, and electrophoretic variation of this protein is determined by an autosomal codominant system. The citizens of Oblong were typed for their transferrin complements. The distribution of transferrin phenotypes was: 100 CC, 100 CD, and 200 DD. What is the frequency of the C allele?
What are the differences between Genetic Engineering and breeding?
