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.

In a particular lizard species, green skin (G) is dominant to blue skin (g). You decide to cross a lizard (Parent #1) that is homozygous recessive for skin color with a lizard (Parent #2) that is homozygous dominant for skin color. Set up a Punnett Square for this cross and then answer the following questions. What is the genotype of Parent #1? [Choose ] What is the phenotype of Parent #1? [Choose ] What is the gentype of Parent #2? [Choose ] What is the phenotype of Parent #2? [ Choose ] What percentage of the offspring will have [Choose ] blue skin?

A breeder performed a testcross to find out if his male dog was a purebred black. He got one brown puppy and seven black puppies, did he have the purebred? (explain) What was the genotype of the female dog he used in test cross (BB), (Bb), or (bb)? (explain)

Within a mouse population, the black fur allele (B) is dominant to the white fur allele (b) and the short whisker allele (S) is dominant to the long-whisker allele (s). A heterozygous black-furred short-whiskered mouse is crossed with a homozygous white-furred long-whiskered mouse. What percentage of the offspring will be black-furred with long whiskers?

Can you draw punnet square for F1 and F2 for this cross

(D) 1/6 (E) 1/64 26. In sheep, eye color is controlled by a single gene with two alleles. When a homozygous brown-eyed sheep is crossed with a homozygous green-eyed sheep, blue-eyed offspring are produced. If the blue-cyed sheep are mated with each other, what percent of their offspring will most likely have brown eyes? (A) 0% (В) 25% (C) 50% (D) 75% (E) 100% 27. In peas the trait for tall plants is dominant (T) and the trait for short plants is recessive (t). The trait for yellow seed color is dominant (Y) and the trait for green seed color is recessive (y). A cross between two plants results in 296 tall yellow plants and 104 tall green plants. Which of the following are most likely to be the genotypes of the parents? (A) TTYY x TTYY (В) Туу х ТТYу (C) TIYY x TIYy (D) TIYy x TTYY (E) TtYY x Ttyy 28. In humans, red-green color blindness is a sexlinked recessive trait. If a man and a woman produce a color-blind son, which of the following must be true? (A) The father is color-blind. (B)…

Dr. Thompson learned in her university genetics course to memorize probability outcomes from monohybrid crossing scenarios so there is never a need for drawing Punnett squares or forked line diagrams. Which equation would Dr. Thompson use to predict the probability of obtaining a tester outcome from the cross of MmNn X Mmnn?     a) ¼ mm X ½ nn.   b) ½ mm X ½ nn.   c) ½ Mm X ½ nn.   d) ½ Mm X ¼ nn.

What cross will result in a ratio of 3 dominant phenotype offspring for every 1 recessive offspring?    What cross will result in a 1:2:1 genotype ratio in the offspring?    What cross will result in all homozygous recessive offspring?
