Question

5. (Problem 12b) Assume that plant weight is determinedby a pair of alleles at each of two independently assorting loci (A and a, B and b) that are additive in their effects. Further assume that each allele represented by an uppercase letter contributes 4gto weight and that each allele represented by a lowercase letter contributes 1 gto weight. What is the distribution of weight expected in the Fa progeny? C A. 1/16- 4 g. 4/16- 7g: 6/16 10 g. 4/16 13 g, 1/16 16 g C B. 1/16 -4 g, 416 g, 616 8 g, 4/16- 10 g, 1/16 12 g C C. 1/16 10 g, 16 16 g. 6/16-13 g, 416-4 g; 1/16- 7 g C E. 1/16 4 g, 416-8 g, 6/16 10 g, 4/16-12 g, 1/16- 16 g 3. Blue eyes are recessiveto brown eyes in humans. If the frequency of blue-eyed individuals in a population is 16%, we can calculate that the frequency of the allele for blue eyes is: A. 16%. B. 32%. C. 40% D. 48 C E. None of the above.

    Questions 64-65 refer to the following. In a plant, axial flower (T) is dominant to terminal flower (t) and red fruit color (Y) is dominant to yellow (y). These effects are caused by two independently assorting autosomal genes. An individual terminal red plant was crossed with an individual axial, yellow plant to produce offspring which were 1/2 axial, red: 1/2 terminal, red. The genotype of the crossed terminal red plant was: ttyy ttYy ttYY TTyy Ttyy In the cross described...

    1. A series of unlinked genes contribute in an equal manner to determine the number of flowers in an inflorescence for a plant species. Two pure breeding lines, one with 4 flowers and a second with 12 flowers per inflorescence. After the cross is performed the F1 plants have 8 flowers per inflorescence. The F1 plants as crossed with each other and the resulting F2 produces plants with as few as 4 flowers per inflorescence and as many as 12....

Homozygosity for the recessive allele at either of the loci or at both loci renders the mouse tailless.

For this cross, what fraction will have type O blood? Express your answer as a fraction. Example: 1/8 For this cross, 4/8 will have type O blood. A rare abnormality known as the "Bombay phenotype" is the result of epistatic interaction between the gene for the...
