Question

1. In your opinion, what is one overarching theme of genetics? There is no right or wrong answer, but you must support your position with information learned in class. (20 points)

2. A diploid organism has the genotype AaBbCcDd. The four genes are on different chromosomes. In the diagrams requested, illustrate only these four pairs of chromosomes and label each copy of each allele on chromosomes and sister chromatids. For simplicity assume crossing over is not occurring.

a. Diagram any correct mitotic metaphase, illustrate four pairs of chromosomes, and label the alleles.

b. Diagram any correct meiotic metaphase II, illustrate these four pairs of chromosomes, and label the alleles.

c. Compare the outcome of mitosis with the outcome of meiosis in terms of the number of chromosomesand the genotype of the cells produced.

Answer 1

Answer-1 An overarching theme of genetics is the DNA sequencing. It link all the concepts of genetics with one another. In any theme of genetics the most important thing is the information about the bases present in a sequence, all other things are related to that. If we want to produce recombinants, or production of cloned organisms or genetically modified organism or any other study in genetics then all the work will be started by the information about a particular DNA sequence. So this is the most important and overarching theme of genetics.
