A line of mouse cells is grown for many generations in a medium with 15N. Cells in G1 are then switched to a new medium that contains 14N. Draw a pair of homologous chromosomes from these cells at the following stages, showing the two strands of DNA molecules found in the chromosomes. Use different colors to represent strands with 14N and 15N. Q. Cells in anaphase II of meiosis, after switching to medium with 14N
What is the possible number of gamete cells that can be produced from a diploid 2n=4 taking crossing-over into account?
discuss briefly The genetics of triploidy
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?
Below is a pair of homologous chromosomes. If the A and B genes are on the same chromosome (as shown), what outcome of gametes would you expect to be produced from this individual? B 16 O 50% AB, 50% ab O More Ab gametes than AB gametes O 25% AB, 25%Ab, 25%aB, 25%ab O More AB gametes than Ab gametes
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
Sketch a series of diagrams showing each of the following, making sure to end each series with haploid cells:(a) How a pair of alleles for a single locus segregate in meiosis(b) How the alleles of two unlinked loci assort independently in meiosis(c) How the alleles of two linked loci undergo genetic recombination
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.
