In garden pea plants, tall stem height (T) is dominant over short stem height (t), and round seed shape (R) is dominant over wrinkled seed shape (r). A tall, wrinkled seed plant (Ttrr) is crossed with a tall, round seed plant (TtRR). Which row identifies the gametes produced by these plants? Select one: a. Tall wrinkled  Tall round Tr and tr TR, Tr, tR, and tr b. Tall wrinkled  Tall round Tr and tr TR and tR c. Tall wrinkled  Tall round TR and tR Tr and tr d. Tall wrinkled  Tall round TR, Tr, tR, and tr TR and tR

Miniature wings in Drosophila result from an X-linked allele (w) that is recessive to the allele for long wings (+). In a cross of a long winged male with a long winged female, the following offspring were obtained: 100 long winged males, 106 miniature winged males, and 480 long winged females. Given this result, the female must be a carrier of the miniature wing allele. True False

Drosophila can have a yellow-brown body (wild-type [+]) or a black body [b] as a result of a mutation in the black gene (marked b). a mutation in the black gene (marked b). There is also a mutation in the purple gene (marked pr) which purple eyes (mutant phenotype [pr]). Flies with normal eyes are noted [+]. a/ Pure strains of male Drosophila [b] are crossed with female Drosophila [pr] (1st cross). The F1 progeny contains only wild-type Drosophila for the two [+, +] traits. both [+, +] traits. The reciprocal cross gives the same result. What information can you draw from this?

In Mendelfruit plants, fruit may be either round (RR), long (rr) or oval (Rr). Cross two oval-fruit plants. What is the phenotypic ratio of the resulting offspring?  (what do they LOOK LIKE?) Cross a round-fruit plant and an oval-fruit plant. Give the phenotypic ratio of the offspring.
