Give typing answer with explanation and conclusion to all parts The chromosomes drawn below are found in a human skin cell. The lines represent the chromosomes themselves. The letters indicate the location of a particular version of a gene. a) T/F An individual’s offspring are more likely to inherit a D1 and R together than a D1 and T9 together. b) T/F About 50% of the egg cells from this individual will have both T9 and BA5. c) T/F Because r is recessive, the frequency at which the r version of the gene occurs in a population is lower than the frequency at which the R version occurs in the population. d) T/F If the protein produced by the BA gene is involved in the formation of ovaries, then the BA gene is likely located on a sex chromosome. e) T/F Because the genes shown here are found in skin cells, these genes code for proteins required for skin cell function.
In an electrophoretic gel across which is applied a powerful electrical alternating pulsed field, the DNA of the haploid fungus Neurospora crassa (n = 7) moves slowly but eventually forms seven bands, which represent DNA fractions that are of different sizes and hence have moved at different speeds. These bands are presumed to be the seven chromosomes. How would you show which band corresponds to which chromosome?

Consider the example of the fusion of chromosome 21 and 14. By itself, this fusion does not cause any phenotypic differences in the carrier individuals. However, the children of carriers have a very high rate of down syndrome, as well as low fertility. Explain why this is? Be specific about what differences in chromosome number may occur in offspring, and how this occurs.

Fathers contribute more new point mutations to theirchildren than mothers. You may know from general biology that people have sex chromosomes—two X chromosomes in females and an X plus a Y chromosome inmales. Both sexes have the autosomes (A’s).a. On which type of chromosome (A, X, or Y) wouldyou expect the genes to have the greatest number ofnew mutations per base pair over many generations ina population? Why?b. On which type of chromosome would you expect theleast number of new mutations per base pair? Why?c. Can you calculate the expected number of newmutations per base pair for a gene on the X and Ychromosomes for every one new mutation in a geneon an autosome if the mutation rate in males is twicethat in females?
A cytogeneticist has collected tissue samples from members of acertain butterfly species. Some of the butterflies were located inCanada, and others were found in Mexico. Through karyotyping,the cytogeneticist discovered that chromosome 5 of the Canadianbutterflies had a large inversion compared with chromosome 5 ofthe Mexican butterflies. The Canadian butterflies were inversionhomozygotes, whereas the Mexican butterflies had two normalcopies of chromosome 5.Explain whether a mating between Canadian and Mexicanbutterflies would produce phenotypically normal offspring?
