In a cross in Drosophila, a female heterozygous for the autosomallylinked genes a, b, c, d, and e (abcde/ + + + + +) was testcrossedwith a male homozygous for all recessive alleles (abcde/abcde).Even though the distance between each of the loci was at least3 map units, only four phenotypes were recovered, yielding thefollowing data: Phenotype No. of Flies+ + + + + 440a b c d e 460+ + + + e 48a b c d + 52 Total = 1000 Why are many expected crossover phenotypes missing? Can anyof these loci be mapped from the data given here? If so, determinemap distances.

Concordance studies of twins for a neurodegenerative disorder show MZ= 46% and DZ= 15%. Further studies have shown a possible link to a gene on chromosome 9, however, there are some individuals in the study who have the allele but do not develop the disorder (group 1), and there are other individuals who do not have the allele yet develop the disorder (group 2). Amita's older sister and maternal uncle have this disorder. Currently, Amita & her 2 younger brothers do not show symptoms. Amita's paternal grandfather was rumored to have this disorder. 1. Draw the pedigree for Amita's family and determine the mode of inheritance if any. 2. Explain how the 2 groups in the study could be possible? 3. What would you tell Amita about the heritability of this disorder?

Dominant negative Incomplete dominance Epistasis Recessive lethal allele III ||| E A condition where one gene has the ability to override the expression of another gene no matter what the relationship is between the other gene's alleles. A condition when a new mutation is able to suppress or revert an earlier mutation allowing wildtype function to reappear. A condition where a recessive allele influences the shape of a protein dimer product in the heterozygous condition so that it neither resembles the homozygous dominant nor the homozygous recessive conditions leading to a LOF in the heterozygous state and the recessive state. A condition where two recessive alleles will be fatal to an offspring although it will not affect a
