Unformatted text preview: are crossbred, the result is always is always curly-haired. Two of these curly-haired F 1 s are mated several times, and when the phenotypes of their offspring are tallied, there are 59 curly and 41 straight-haired guinea pigs. When either two straight-haired F 2 s or two curly F 2 s are mated, the offspring are a mix of straight- and curly-haired pups. This trait involves two genes. a. (1 pt) What is the pattern of inheritance displayed by this trait? ________________________ b. (2 pts) What are the genotypes of the two parents? _______________ and _______________ c. (1 pt) What is the expected ratio of straight:curly? d. (4 pts) Draw a Punnett square of the cross between two of the curly-haired F 1 s on the back. 4. (1 point extra credit). Heffalumps are usually solid gray, but one variety has pink spots. This variety is exclusively male, and if a male has pink spots, its male parent and male children also have spots. What is the likely pattern of inheritance of this trait?...
