A normal chromosome and its homolog carrying an inversion are given below (* Y= centromere): Normal: ABCD * EFGH Inversion:a fe* dcbgh Answer the following questions about these homologs (8 points total) What gamete genotypes are produced if there is a crossover between G & H? Be sure to include a * to show the position of the centromere. Put each gamete on a separate line, and write (V) or (1) beside each gamete to indicate whether it is viable...
A normal chromosome and its homolog carrying an inversion are given below (* Y= centromere): Normal: ABCD * EFGH Inversion:a fe* dcbgh Answer the following questions about these homologs (8 points total) What gamete genotypes are produced if there is a crossover between B & C? Be sure to use a * to indicate the position of the centromere. Put each gamete on a separate line, and write (V) or (I) beside each one to indicate whether it is viable...
11. A normal chromosome and its homolog carrying an inversion are given below (Y* = centromere) Normal: ABCDEFGH Inversion: a dcbe*fgh Answer the following questions about these homologs (8 points total) 11b. Diagram the alignment of these homologs during meiosis in an inversion heterozygote (be sure to include all of the chromatids). (2 points)
A normal chromosome and its homolog carrying an inversion are given below (* Y= centromere): Normal: A B C D * EFGH Inversion:a fe* dcbgh Answer the following questions about these homologs (8 points total) With pen and paper, diagram the alignment of these homologs during meiosis in an inversion heterozygote. Be sure to include all chromatids.
11. A normal chromosome and its homolog carrying an inversion are given below (Y* = centromere) Normal: ABCDEFGH Inversion: a dcbe*fgh Answer the following questions about these homologs (8 points total) 11d. Imagine one population of mice is homozygous for the 'normal' chromosome. A nearby population is homozygous for the 'inversion' chromosome. Can gene flow occur between these two populations? Why or why not? (Your answer should include a brief definition of gene flow, and an explanation as to why...
Genetics DEFGHIJKL 1. A normal chromosome has the following gene sequence: ABC centromere An inversion heterozygote has the following inverted gene sequence: ABJIHGFED-centromere CKL What would be the product if a crossover occurred between genes H and I on one inverted and one normal chromosome? (1 point) 2. A normal chromosome has the following gene sequence: AB centromere CDEFGHIJKL An inversion heterozygote has the following inverted gene sequence: AB-centromere CDJIHGFEKL What would be the product if a crossover occurred between...
1. For the two situations shown below, draw the chromosomes that would be present during metaphase of meiosis I if there was a crossover between C and D. Also indicate whether the resulting gamete produced by meiosis would be viable after fertilization with a normal gamete. a. The heterozygote has one normal chromosome... Paracentric inversion ... and one chromosome with an inverted segment Formation of inversion loop In prophase 1 of meiosis, the chromosomes form an inversion loop, which allows...
19. A viable inversion heterozygote is undergoing meiosis. The chromosomes are illustrated below. Compare the consequences of crossing over in two cases: crossing over between C and D, and crossing over between F and G ABCDEFGHIJK 2 ABCHG FEDIJK 20. Using the same inverted chromosome above: a. Two crossing over events occur among these chromatids: a crossover between genes H and G on chromatids 2 and 4, and a crossover between genes D and E on chromatids 1 and 3....
