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?
Consider an individual with the AB/ab genotype, and assume that alleles of the A and B genes areunable to recombine during meiosis. If this individual is crossed with an individual who is homozygousrecessive at both genes (ab/ab), what is the expected phenotype ratio in the offspring?
When Calvin Bridges observed a large number of offspring from a cross of white-eyed female Drosophila tored-eyed males, he found very rare white-eyed femalesand red-eyed males among the offspring. He was ableto show that these exceptions resulted from nondisjunction, such that the white-eyed females had received twoXs from the egg and a Y from the sperm, while thered-eyed males had received no sex chromosome fromthe egg and an X from the sperm. What progeny wouldhave arisen from these same kinds of nondisjunctionalevents if they had occurred in the male parent? Whatwould their eye colors have been?

If a female is heterozygous for an X-linked allele, how many different types of gametes can she produce with respect to this allele?arrow_forwardHuman females have two X chromosomes (XX); males have one X and one Y chromosome (XY). a. With respect to X-linked alleles, how many different types of gametes can a male produce? b.

A cross of two erminettes produced a totalof 48 progeny, consisting of 22 erminettes, 14 blacks,and 12 pure whites. What genetic basis of the erminette pattern is suggested?

- For each of the following genotypes, what tyoes of gametes will be produced?arrow_forwardIn 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_forwardIn Neurospora, his2 mutants require the amino acidhistidine for growth, and lys4 mutants require theamino acid lysine. The two genes are on the samearm of the same chromosome, in the ordercentromere - his2 - lys4.A his2 mutant is mated with a lys4 mutant. Draw all ofthe possible ordered asci that could result from meioses in which the following events occurred, accountingfor the nutritional requirements for each ascospore.Ascospores without any copy of a chromosome willabort and die, turning white in the process.a.

- In Drosophila, a cross was made between a yellowbodied male with vestigial (not fully developed)wings and a wild-type female (brown body). The F1generation consisted of wild-type males and wild-typefemales. F1 males and females were crossed, and theF2 progeny consisted of 16 yellow-bodied males withvestigial wings, 48 yellow-bodied males with normalwings, 15 males with brown bodies and vestigialwings, 49 wild-type males, 31 brown-bodied femaleswith vestigial wings, and 97 wild-type females.Explain the inheritance of the two genes in questionbased on these results.arrow_forwardTable shows that Turner syndrome occurs when an individualinherits one X chromosome but lacks a second sex chromosome.Can Turner syndrome be due to nondisjunction duringoogenesis, spermatogenesis, or both? If a phenotypically normalcouple has a color-blind child (due to a recessive X-linkedallele) with Turner syndrome, did nondisjunction occur duringoogenesis or spermatogenesis in this child’s parents? Explainyour answer.arrow_forwardIn examining a large sample of yeast colonies on a petridish, a geneticist finds an abnormal-looking colonythat is very small. This small colony was crossed withwild type, and products of meiosis (ascospores) werespread on a plate to produce colonies. In total, therewere 188 wild-type (normal-size) colonies and 180small ones.a. What can be deduced from these results regardingthe inheritance of the small-colony phenotype? (Inventgenetic symbols.)b. What would an ascus from this cross look like?arrow_forward
- 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?arrow_forwardFor a certain chromosomal region, the mean number of crossovers at meiosis is calculated to be two per meiosis. In that region, what proportion of meioses are predicted to have (a) no crossovers? (b) one crossover? (c) two crossovers?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_forward
