2). What is the maximum frequency of recombinant gametes? Illustrate this in an F1 individual with 2 chromosomes, heterozygous for 2 linked genes, with a single cross-over during Meiosis.

in the experiment of following chromosomal dna mvement througgh meiosis, why. do you use non-sister chromatids to demobstrate crossing over? what combinatiobns of alleles could result from a crossover between BD and bd chromosomes? Identify two ways that meiosis contributes to genetic recombination. Why is it necessary to reduce the number of chromosomes in gametes, but not in other cell?

3. An inversion heterozygote has the following inverted chromosome: Centromere )))))))))))) A B JI HGF ED CKLM Inverted region What would be the products if a crossover occurred between the genes F and E on the inverted chromosome and the normal chromosome?

Please explain the outcomes of nondisjunction in meiosis one versus nondisjunction in meiosis two, in terms of the effect on the gametes. Please give an example of a defect that results from nondisjunction in meiosis.

Meiotic nondisjunction usually occurs during meiosis I. What isnot separating properly: bivalents or sister chromatids? What is notseparating properly during mitotic nondisjunction?

In a diploid organism that has a haploid complement of n=10, what is the formula and chromosome compliment of each individual? Chromosome complement Formula Total number of chromosomes 1. Trisomy      2. Monosomy     3. Tetraploid      4. Triploid

In fruit flies, chromosomal crossing over does not occur in meiosis in males, whereas crossing over does occur in meiosis in females. In fruit flies that are heterozygous at many genes (i.e. many maternal and paternal versions of the genes differ), at what stage would cells no longer be heterozygous for any gene during the process of meiosis? a)After the second meiotic division in males, and after the first meiotic division in females. b)After the second meiotic division in both males and females. c)After the first meiotic division in both males and females. d)After the first meiotic division in males, and after the second meiotic division in females.
