A tomato geneticist attempts to assign five recessivemutations to specific chromosomes by using trisomics.She crosses each homozygous mutant (2n) with each ofthree trisomics, in which chromosomes 1, 7, and 10 takepart. From these crosses, the geneticist selects trisomicprogeny (which are less vigorous) and backcrosses themto the appropriate homozygous recessive. The diploidprogeny from these crosses are examined. Her results, inwhich the ratios are wild type:mutant, are as follows:Which of the mutations can the geneticist assign towhich chromosomes? (Explain your answer fully.)
The a, b, and c loci are all on different chromosomesin yeast. When a b+ yeast were crossed to a+ b yeastand the resultant tetrads analyzed, it was found thatthe number of nonparental ditype tetrads was equal tothe number of parental ditypes, but there were no tetratype asci at all. On the other hand, many tetratypeasci were seen in the tetrads formed after a c+ wascrossed with a+ c, and after b c+ was crossed withb+ c. Explain these results.
. Chromosome 3 of corn carries three loci (b for plant-color booster, v for virescent, and lg for liguleless).

The human genome consists of 23 pairs of chro-mosomes (22 pairs of autosomes and one pair of sex chro-mosomes). During meiosis, the maternal and paternal setsof homologs pair, and then are separated into gametes, sothat each contains 23 chromosomes. If you assume thatthe chromosomes in the paired homologs are randomlyassorted to daughter cells, how many potential combina-tions of paternal and maternal homologs can be gener-ated during meiosis? (For the purposes of this calculation,assume that no recombination occurs.)

A couple planning their family are aware that through the pastthree generations on the husband’s side a substantial numberof stillbirths have occurred and several malformed babies wereborn who died early in childhood. The wife has studied geneticsand urges her husband to visit a genetic counseling clinic,where a complete karyotype-banding analysis is performed.Although the tests show that he has a normal complement of46 chromosomes, banding analysis reveals that one memberof the chromosome 1 pair (in group A) contains an inversioncovering 70 percent of its length. The homolog of chromosome1 and all other chromosomes show the normal bandingsequence. Question: How would you explain the high incidence of paststillbirths?
