- Assume that a meiotic-nondisjunction event causes trisomy 8 in a newborn. If two of the three copies of chromosome 8 are absolutely identical, at what point during meiosis did the nondisjunction event take place?arrow_forwardIn the haploid yeast Saccharomyces cerevisiae, the twomating types are known as MATa and MATα. You cross apurple (ad-) strain of mating type a and a white (ad+)strain of mating type α. If ad- and ad+ are alleles of onegene, and a and α are alleles of an independently inherited gene on a separate chromosome pair, what progenydo you expect to obtain? In what proportions?arrow_forwardThough an individual with abberations such as Robertsonian translocation may be phenotypically normal, they can generate gametes through meiosis that have atypical organizations of chromosomes, resulting in recurrent fetal abnormalities or miscarriages. Why, despite these Robertsonian translocations, are affected cells still able to generate typical gametes through meiosis?arrow_forward
- In Figure 4-3, would there be any meiotic products thatdid not undergo a crossover in the meiosis illustrated? Ifso, what colors would they be in the color conventionused?arrow_forwardA diploid (2n) trihybrid individual with the genotype EeFfGg can make eight genetically different gametes. Loci E/e and F/f are on chromosome 1 and locus G/g is on chromosome 2. Explain how a gamete containing the alleles e, f and g may be produced by meiosis. Refer specifically to meiotic events occurring during Prophase I, Metaphase I, Anaphase I and Anaphase II. (NB: remember to refer to the organism above).arrow_forwardA diploid species with 44 chromosomes (i.e., 22 per set) is crossedto another diploid species with 38 chromosomes (i.e., 19 per set).How many chromosomes are produced in an allodiploid orallotetraploid from this cross? Would you expect the offspring tobe sterile or fertile?arrow_forward
- A 2n=4 plant is heterozygous at two genes, one controlling plant height (T = tall, t= short) and one controlling disease resistance (D = resistant, d = susceptible). The plant height gene is located on one chromosome, and the disease resistance gene is located on the other chromosome. In the cells below, draw to two possible arrangements of the chromosomes at metaphse I of meiosis. Hint: look at Figure 2.17 in your textbook for an example of how chromosomes can be arranged at metaphase I. Be sure to label the alleles present at the genes on the two chromosomes in each drawing. 00arrow_forwardSuppose that meiosis occurs in the transient diploid stageof the cycle of a haploid organism of chromosome number n. What is the probability that an individual haploidcell resulting from the meiotic division will have a complete parental set of centromeres (that is, a set all fromone parent or all from the other parent)?arrow_forwardMeiotic nondisjunction is much more likely than mitotic nondisjunction.Based on this observation, would you conclude that meioticnondisjunction is usually due to nondisjunction during meiosisI or meiosis II? Explain your reasoning?arrow_forward
- In a vial of Drosophila, a research student noticedseveral female flies (but no male flies) with bag wingseach consisting of a large, liquid-filled blister insteadof the usual smooth wing blade. When bag-wingedfemales were crossed with wild-type males, 1/3 of theprogeny were bag-winged females, 1/3 were normalwinged females, and 1/3 were normal-winged males.Explain these results.arrow_forwardAn individual heterozygous for a reciprocal translocation possesses the following chromosomes: A B • C D E F G A B • C D V W X R S • T U E F G R S • T U V W X Q. Diagram the alternate, adjacent-1, and adjacent-2 segregation patterns in anaphase I of meiosis.arrow_forwardConsider a cell with 2 pairs of homologous chromosomes where Chromosome 1 with genes VWXYZ is the homolog of Chromosome 2 with genes vwxyz while Chromosome 3 with genes PQRST is the homolog of Chromosome 4 with genes parst. If a reciprocal translocation occurred between Chromosome 1 YZ genes and Chromosome 3 ST genes, give the following gamete types produced after meiosis: (Answer in Arabic numbers only) 1. Gamete/s with non-recombinant chromosomes 2. Gamete/s with 1 recombinant chromosome 3. Gamete/s with 2 recombinant chromosomes 4. Gamete/s with gene duplications 5. Gamete/s with gene deletions 6. Gamete/s with 2 normal chromosome sequences 7. Gamete/s with 1 normal chromosome sequence 8. Gamete/s with balanced translocation 9. Gametes/ with all dominant genes 10. Gamete/s with all recessive genes 11. Gamete/s with 10 different genes 12. Gamete/s with TSXWV genes 13. Gamete/s with vwxyz genes 14. Gamete/s with pqrst genes 15.Gamete/s with PORYZarrow_forward
