Morgan first suggested that theoriginal white-eyed male had two copies of the white-eye allele. Inthis problem, let’s assume that he meant the fly was XwYwinstead ofXw Y What crosses would need to be made to rule out the possibility thatthe Y chromosome carries a copy of the eye color gene?
The karyotype of a young girl who is affected with familialDown syndrome revealed a total of 46 chromosomes. Her olderbrother, however, who is phenotypically unaffected, actually had45 chromosomes. Explain how this could happen. What wouldyou expect to be the numbers of chromosomes in the parents ofthese two children?
On rare occasions, a human male is born who is somewhat feminizedcompared with other males. Microscopic examination of the cells ofone such individual revealed that he has a single Barr body in eachcell. What is the chromosomal composition of this individual?
With regard to the analysis of chromosome structure, explain theexperimental advantage that polytene chromosomes offer. Discusswhy changes in chromosome structure are more easily detected inpolytene chromosomes than in ordinary chromosomes.
In 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?
A couple planning their family are aware that through the past threegenerations on the husband's side a substantial number of stillbirthshave occurred and several malformed babies were born who diedearly in childhood. The wife has studies genetics and urges herhusband to visit a genetic counseling clinic, where a completekaryotype-banding analysis is performed. Although the tests showthat he has a normal complement of 46 chromosomes, bandinganalysis reveals that one member of the chromosome 1 pair (ingroup A) contains an inversion covering 70 percent of its length.The homolog of chromosome 1 and all other chromosomes showthe normal banding sequence.(a) How would you explain the high incidence of past stillbirths?predictabouttheprobabilityof(b) What can you abnormality/normality of their future children?(c) Would you advise the woman that she will have to bring each pregnancy to term to determine whether the fetus is normal? Ifnot, what else can you suggest?
In 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.

. Among adults with Turner syndrome, it has beenfound that a very high proportion are genetic mosaics.These are of two types: In some individuals, themajority of cells are XO, but a minority of cellsare XX. In other Turner individuals, the majorityof cells are XO, but a minority of cells are XY.Explain how these two patterns of somatic mosaicscould arise.
A woman with achondroplasia (a dominant form of dwarfism) anda phenotypically unaffected man have seven children, all of whomhave achondroplasia. What is the probability of producing such afamily if this woman is a heterozygote? What is the probabilitythat the woman is a heterozygote if her eighth child does not havethis disorder?
On rare occasions, an organism may have three copies of achromosome and therefore has three copies of the genes on thatchromosome (instead of the usual number of two copies). Forsuch a rare organism, the alleles for each gene usually segregateso that a gamete will contain one or two copies of the gene. Let’ssuppose that a rare pea plant has three copies of the chromosomethat carries the height gene. Its genotype is TTt. The plant is alsoheterozygous for the seed color gene, Yy, which is found on adifferent chromosome. With regard to both genes, how manytypes of gametes can this plant make, and in what proportions?(Assume that it is equally likely that a gamete will contain oneor two copies of the height gene.)
