All of the progeny are yellow. When the reciprocal cross is performed, all of the progeny are green. What do these results suggest? Yellow is completely dominant to green. Color is determined by a sex-linked gene The yellow and green alleles are codominant. Color is maternally inherited. 1 / 1 pts Question 2 Which of the following statements is true of a heteroplasmic gene? A heteroplasmic gene is found in multiple allelic forms within the nuclear genomes of different cells of an organism. A heteroplasmic gene is found in multiple allelic forms in DNA molecules that make up the genomes of organelles in the cells of an organism. Heteroplasmic genes have Mendelian inheritance patterns. All copies of this nuclear gene are identical.

They are paternally inherited. Phenotype is usually restricted to a single process or trait. They are pleiotropic. 1 / 1 pts Question 4 What kind of analysis is needed to determine whether two mutations are in the same gene or in different genes? genetic mapping complementation analysis analysis of the correspondent genomic library positional cloning

Which of the features of Drosophila made it a fortuitous choice for Morgan and his colleagues? large number of visible phenotypes both sexual and asexual reproduction having a long life cycle well-known biochemical pathways especially high rate of mutation 1 / 1 pts Question 6 Describe how you would identify mutations that are dominant. To identify dominant mutations, breed the mutant individual to a mutant individual. Dominant mutations will be visible in the F2 generation.
