Say a rare species of butterfly has two versions of color called blue (B) and white (b). You want to repopulate the species for the wild, but also breed and sell them. You find the blue butterflies are the most appealing to customers and want to breed them for the maximum profit. Blue is BB and Bb, while white is bb. State the percent change of getting blue butterflies from the following crosses: 5. Blue (BB) and White (bb) 6. Blue (Bb) and White (bb) 7. Blue (BB) and Blue (BB) 8. Blue (Bb) and Blue (Bb) 9. White (bb) and White (bb)

Wild type fruit flies have red eyes and normal wings. You crossed a male from a pure-breeding, purple-eyed, broken-winged line of fruit flies to a female from a pure-breeding, red-eyed, normal-winged line of fruit flies. All the F1 progeny were wild type. The reciprocal cross gave the same result. The F1 flies from the first cross were mated to produce an F2 population. If there were 528 flies in the F2 population how many would be purple-eyed and normal winged? 396 264 297 99 352

In a plant, stems can appear fuzzy or smooth. The allele for fuzzy (F) is dominant.  These plants can also have blue (B-) or white flowers.  White is the recessive trait.  A cross was made between plants heterozygous for both traits.  You observed 290 blue fuzzy, 80 blue smooth, 70 white fuzzy, and 40 white smooth plants.  Are your observations consistent with your expectations?

In peas, yellow pods are dominant to green pods. Show the results of a cross between a pure yellow plant and a hybrid yellow plant. RA + v в I Paragraph

In pea plants yellow seed color, (GG) and round seed shape (WW) seeds are dominant traits, while green color or (gg) wrinkled shape (ww) seeds are recessive traits. You cross a pure breeding plant with yellow wrinkled seeds to a pure breeding plant with green round seeds to generate F1s. When you perform a reciprocal cross you get the same results. You take an F1 male and an F1 female and generate an F2 population. Of all the F2 offspring you count 18 that have yellow wrinkled seeds. Based on this information, how many F2 offspring do you expect to display only dominant traits? a) 72 b) 54 c) 18 d) 24 e) 6

Suppose a species of tulip has three alleles for the gene that codes for flower color. The CR allele produces red tulips, the CP allele produces purple tulips, and the C" allele produces white tulips. CR is dominant over CP and Cw, and CP is dominant over Cu . For each cross, determine the expected phenotype ratio of offspring flower color. CRCP X CPCW CRCW x CPCW. 1 red: 3 purple : 0 white 2 red: 0 purple : 2 white Expected phenotype ratio Answer Bank 1 red: 2 purple : 1 white 2 red: 2 purple: 0 white 1 red : 1 purple : 0 white 2 red : 1 purple : 1 white
