2, An individual is heterozygous for an inversion
chromosome as shown below:
A. Draw the looped arrangement of the chromosomes that
you would expect to see when they are paired for meiosis I.
(Although there are four strands present at meiosis I, only two are
shown here; you need only draw two strands).
B. Assume that a crossover
exchange takes place in the interval between T and E at meiosis I.

5. (16 pts.) A cell has two pairs of submetacentric chromosomes, which we wili cail chromosomes I,, Ib, Ila, and Ilb. Submetacentric chromosomes have their centro nere abou midway between the telomere and middle of the chromosome as shown. Chromosomes Ia and I, are homologues and chromosomes II, and Ilb are homologues. Allele R is located on the p arm (short arm) of chromosome of chromosome la, and allele r is located at the same position on chromosome lb. Allele...

2. You have a fly strain heterozygous for a reciprocal translocation between an acrocentric chromosome (solid) and a metacentric chromosome (wavy). The normal homologues have dominant alleles for the genes shown, while the re-arranged chromosomes have recessive alleles. A B F G NOR a bf an anong A. (3pts) What kind of gametes can a male of this strain produce? (note that there is no recombination in Drosophila males) B. (3pts) If you performed a test cross of a male...

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....

question b-f please thank you
12:52 PM Mon Apr 13 78% B06 Draw a diagram to represent the equational division of meiosis for a diploid organism with three heterologous chromosomes. One acrocentric, one metacentric and one telocentric. The diagram should show the chromosomes as you'd expect to see them during metaphase. The organism is trihybrid and heterozygous for dominant and recessive alleles at three different loci. Locus A is on the telocentric chromosome. Locus B is on the metacentric chromosome....

please solve this asap thank you so much
1 Draw out the phases of meiosis for a (2n=4) germ line cell: Use red and blue to indicate ate the two sets of chromosomes aleat There should be two throughout the various phases-red will represent the maternal set and blue will represent the paterials alternate scenarios for how the homologous pairs could alian during metaphase. When applicable, bus pairs could alian during metaphase. When applicable, all of the phase drawings (pre-...
