SOLVED: Finn listed two of the three steps involved in gene therapy.1. The normal allele is removed from the chromosome. 2. The normal allele is added to the cells of a person with the disorder.Which step should he also include, and where? A.The normal allele is copied before step 1. B.The normal allele is copied after step 1. C.The unhealthy gene is cut from the DNA before step 2. D.The unhealthy gene is cut from the DNA after step 2.

In a diploid organism of genotype A / a ; B / b ; D / d, the allele pairs are all on different chromosome pairs. The two diagrams in the next column purport to show anaphases ("pulling apart" stages) in individual cells. State whether each drawing represents mitosis, meiosis I, or meiosis II or is impossible for this particular genotype. | Numerade

In Drosophila, vermilion eye color is due to a recessive allele (v) located on the X chromosome. Curved wings is due to a recessive allele ( c u ) located on one autosome, and ebony body is due to a recessive allele ( e ) located on another autosome. A vermilion male is mated to a curved, ebony female, and the F1 males are phenotypically wild-type. If these males were backcrossed to curved, ebony females, what proportion of the F2 offspring will be wild-type males? | Numerade

SOLVED:A tomato geneticist working on F r, a dominant mutant allele that causes rapid fruit ripening, decides to find out which chromosome contains this gene by using a set of lines of which each is trisomic for one chromosome. To do so, she crosses a homozygous diploid mutant with each of the wild-type trisomic lines.a. A trisomic F1 plant is crossed with a diploid wildtype plant. What is the ratio of fast- to slow-ripening plants in the diploid progeny of this second cross if F r is on the tri

SOLVED:A yellow body in Drosophila is caused by a mutant allele y of a gene located at the tip of the X chromosome (the wild-type allele causes a gray body). In a radiation experiment, a wild-type male was irradiated with X rays and then crossed with a yellow-bodied female. Most of the male progeny were yellow, as expected, but the scanning of thousands of flies revealedtwo gray-bodied (phenotypically wild-type) males. These gray-bodied males were crossed with yellow-bodied females, with the fol
