Wolves are observed having Grey fur (G) dominant to Black fur (g), Blue eyes (B) dominant to Yellow eyes (b). In the P1 generation, wolves GGbb and ggBB are crossed: You cross 2 wolves from the F1 generation to make the F2 generation. What are the odds an F2 wolf will have the GgBb genotype?

In moose, brown coat color (B) is dominant to albino (no pigment) (b) and rough coat (R) is dominant to smooth coat (r). Two moose are selected for breeding and their genotypes are BBrr and bbRR. The F1 offsprings are then crossed to each other. What is the expected fraction of moose in the F2 that will be albino with a rough coat? a) 1/16 b) 3/16 c) 9/16 d) 1
Wolves are observed having Grey fur (G) dominant to Black fur (g), Blue eyes (B) dominant to Yellow eyes (b). In the P1 generation, wolves GGbb and ggBB are crossed: What phenotype and genotype will the F1 generation have?
In butterflies, blue wings (B) are dominant over yellow wings (b), and stripes (S) are dominant over no stripes (s). These genes for these two characteristics assort independently. A homozygous butterfly with yellow wings and no stripes is crossed with a homozygous butterfly that has blue wings and stripes. Afterward, individuals from this F1 generation were crossed obtaining a total of 272 butterflies as follows: 135 blue-winged butterflies with stripes, 55 blue with no stripes, 57 yellow with stripes, and 25 yellow without stripes.

A male dog with the genotype GgBb is crossed with a female dog with the genotype GgBb. Set up a punnet square Note: Gray hair (GG) is dominant over white hair (gg); Black eyes (BB) is dominant over red eyes (bb). (a) How many out of 16 have gray fur and black eyes? (b) How many out of 16 have gray fur and red eyes? (c) How many out of 16 have white fur and black eyes? (d) How many out of 16 have white fur and eyes red? Write the phenotypic ratio.
The phenotype of spotting in dogs (A) is dominant to no spots (a). When 2 heterozygous spotted dogs are crossed (Aa X Aa), the outcome is shown below: 2/3 Spots 1/3 No Spots What is the best explanation for this outcome, and what are the genotypes of spotted and non-spotted offspring?
In a cross between a black and a white cat, all members of the Fi generation are black. The F2 generation is made up of approximately 3/4 black and 1/4 white cat. (i) Diagram this cross, showing the genotypes and phenotypes of the parents, F, and F2 generations. What is the probability that the first two offspring will be homozygous and the third is white if an Ficat is test crossed?
A homozygous plant with 20-cm-diameter flowers is crossed with a homozygous plant of the same species that has 40-cm-diameter flowers. The F1 plants all have flowers 30 cm in diameter. In the F2 generation of 512 plants, 2 plants have flowers 20 cm in diameter, 2 plants have flowers 40 cm in diameter, and the remaining 508 plants have flowers of a range of sizes in between. (a) Assuming all alleles involved act additively, how many genes control flower size in this plant? (b) What frequency distribution of flower diameter would you expect to see in the progeny of a backcross between an F1 plant and the large-flowered parent?

A) If the F1 is self-crossed and 400 F2 plants are raised, how many would be expected in each phenotypic class? B) How many of the F2 would be expected to be pure breeding when selfed?
