Many fire stations handle emergency calls for medical assistance as well as calls requesting firefighting equipment. A particular station says that the probability that an incoming call is for medical assistance is .85. Assuming that successive calls are independent of one another, what is the probability that two successive calls will both be for medical assistance?

In corn, purple kernels are dominant over yellow kernels and full kernels are dominant over shrunken kernels. A corn plant having purple and full kernels is crossed with a plant having yellow and shrunken kernels, and following progeny are obtained   Phenotypes Number observed Purple, Full 112 Purple, Shrunken 103 Yellow, Full 91 Yellow, Shrunken 94 Total: 400 Based on the chi-square test, can we conclude that the progeny are segregating in the expected ratio and the variation between the expected and observed numbers is due to chance?

Hair color is determined in Labrador retrievers by alleles at the B and E loci. A dominant allele B encodes black pigment, whereas a recessive allele b encodes brown pigment. Alleles at a second locus affect the deposition of the pigment in the shaft of the hair. Dominant allele E allows dark pigment (black or brown) to be deposited. Recessive allele e prevents the deposition of dark pigment, causing the hair to be yellow. A black female Labrador retriever was mated with a yellow male. Half of the puppies were black, and half were yellow. If the genotype of the black female parent was Bb Ee, then what was the genotype of the other parent?
