4 A research lab is working with D. melanogaster. It was found that normal wing shape is recessive curly wings. Determine the genotypic & phenotypic ratios of any possible fruit fly offspring if a normal-winged fly is crossed with a curly-winged fly that is known to be heterozygous. Shorthorn cattle exhibit codominance for hair color traits. It is known one homozygous phenotype is pigmented hair (C R ). The other homozygous phenotype is white. The heterozygous phenotype is referred to as roan. Determine the genotypic & phenotypic ratios of a cross between pigmented cow and a roan bull. 4

5 Gene Linkage I II III

6 Recessive allele A couple is interested in having a child. They want to know the possible blood types of any offspring. The father knows he is heterozygous for type-a blood. The mother knows she is homozygous for type-b blood. Determine the genotypic & phenotypic ratios of all the possible offspring. 6

7 Heterozygous Red-Green color blindness is an X-linked recessive disorder (X c ). If a female carrier mates with a normal-vision male, what is the probability one of their sons could be color blind? What is the probability one of their daughters could be color blind? In addition, determine the genotypes of the two parents. 7

12 Mendel collected data on one of his crosses for flower color of pea plants. After counting all of the offspring, Mendel found 1235 plants were purple; 1211 plants were white. Determine the phenotypic ratio of the offspring produced in this cross. Use this to determine the genotypes of the two parental pea plants. Allele 12
