What is the importance of genetics?
Suppose you are heterozygous for a mutant beta-thalassemia allele. If the frequency of beta-thalassemia is 1/1600 persons, what is the probabilty that your prospective spouse is heterozygous for a mutant beta-thalassemia allele?
What is the difference between an allele and a mutation?
what is the difference between muton and recon?
A number of plant species have a recessive allele for albinism; homozygous albino (white) individuals are unable to synthesize chlorophyll. If a tobacco plant heterozygous for albinism is allowed to self-pollinate and 500 seeds germinate: a)how many offspring will be the same genotype as the parent? b)how many seedlings would you expect to be white?
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?
Is There any way in which a currently living could be mutated in reality to such a large scale as to which others could see the mutation, such as a third arm?
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?
which protein contains all the 20 amino acids?
what is virgin sex?
normally on which plants generally genetic studies are being made?
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?
