- Gametes of pureline diploid organisms are_____________________ (please select all correct answer options). have one copy of each gene in the genome heterozgyous homozygous haploidPlease answer appropriately and do not copy-paste from Chegg or anywhere else. Give explanations to your answer. Diagram the types of gametes you would expect from a ++/yw female, given no crossovers, one crossover, two crossovers, three crossovers, and fours crossovers between non-sister chromatids of homologous chromosomes?A woman who sought genetic counseling is found to be heterozygousfor a chromosomal rearrangement between the second andthird chromosomes. Her chromosomes, compared to those in anormal karyotype, are diagrammed on the next page:(a) What kind of chromosomal aberration is shown? (b) Using a drawing, demonstrate how these chromosomeswould pair during meiosis. Be sure to label the differentsegments of the chromosomes.(c) This woman is phenotypically normal. Does thissurprise you? Why or why not? Under what circumstancesmight you expect a phenotypic effect of such arearrangement? The woman in above problem has had two miscarriages. Shehas come to you, an established genetic counselor, with thesequestions:(a) Is there a genetic explanation of her frequent miscarriages?
