our hair comes from our mother's father.Is it true or not? 632
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? 1610
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. 2304
In horses coat color is dependent upon genes as follows: A_B_ results in bay, aaB_ in black, A_bb in chestnut, aabb in liver. In addition, palimino is derived by Dd with chestnut. A palimono stallion (DdAAbb) is crossed with a palimino mare (DdAAbb). What percent of the offspring will be palimino? 504
Explain in terms of gene product function how a mutant allele can be dominant? recessive? 577
Is Recombination in Human Mitochondrial DNA really possible? 695
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? 643
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? 672
What are the differences between Genetic Engineering and breeding? 947
What are the dangers of Genetically Engineered foods? 495
In cats yellow is due to gene B and black to its allele b. These genes are located on the X chromosome (sex-linked). The heterozygous results in calico (tortoise shell). What kinds of offspring (sex & color) are expected from the cross: black male & calico female? Most calico males are sterile, why? 920
Has vitamin c been produced in a human naturally before? 582
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? 987
