In humans the absence of a cleft chin is dominant to the presence of a cleft chin. Two individuals, both of whom are heterozygous for a recessive allele that causes the cleft chin phenotype have 5 children, what is the probability that 3 of their children would not have a cleft chin and 2 would have a cleft chin? 0.0037 0.026 0.237 0.264
Orange coat color in cats is due to an X-linked allele (XO) that iscodominant with the allele for black (X+). When genotypes at the orangelocus were determined for a sample of cats in Minneapolis and St. Paul,Minnesota, the following data were obtained:XOXO females 11XOX+ females 70X+X+ females 94XOY males 36X+Y males 112Calculate the frequencies of the XO and X+ alleles for this population.
For the following five questions, A = true, and B = false 18. (2 pts) The dominance of an allele may vary for different traits. 19. (2 pts) Loss-of-function alleles are recessive, not dominant. 20. (2 pts) A haplosufficient allele is able to produce a wild-type phenotype in the heterozygous state. 21. (2 pts) The permissive temperature, which is usually lower than the normal growth temperature, is the temperature at which a mutant phenotype becomes observable. 22. (2 pts) In a cross between two true-breeding recessive mutants that are affected in different genes, the proportion of F1 progeny that show complementation (the wild-type phenotype) is affected by the map distance between the two genes.

Consider two blood polymorphisms that humans have in addition to the ABO system. Two alleles LM and LN determine the M, N, and MN blood groups. The dominant allele R of a different gene causes a person to have the Rh+ (rhesus positive) phenotype, whereas the homozygote for r is Rh− (rhesus negative). Two men took a paternity dispute to court, each claiming three children to be his own. The blood groups of the men, the children, and their mother were as follows:From this evidence, can the paternity of the children be established?
In a population of 2000 gaboon vipers a genetic difference with respect to venom lethality exists at a single locus. The two alleles (V & v) display incomplete dominance. The population consists of 100 homozygous recessive, non-venomous vipers; 800 heterozygous, mildly-venomous vipers; and 1100 homozygous dominant, deadly-venomous vipers. What is the actual frequency of the recessive allele in the population? /

The ability to taste the chemical compound PTC (phenylthiocarbamide) is coded for by a single gene with two alleles. Let T stand for the allele that codes for tasting and t for the allele that codes for non-tasting. This allele exhibits complete dominance, such that heterozygotes can also taste PTC. Suppose that out of a population of 100 students, 70 are tasters. Estimate the allele frequencies and the frequencies of TT, Tt and tt genotypes in the population. Show all your work, and clearly state your logic and any assumptions you make in estimating the frequencies
