You have a purebreeding line of blue frogs and a purebreeding line of red frogs. You cross them and all the F1 frogs are purple. You cross two of the F1 frogs to one another and get 1/4 red offspring, 1/4 blue offspring and 1/2 purple offspring. What phenotypic ratio would you get if you crossed a purple frog to a red frog? Group of answer choices A. 1/2 purple, 1/2 red B. 1/2 purple, 1/2 blue C. 3/4 purple, 1/4 red D. 1/2 blue, 1/2 red

If RR stands for red, RR' stands for roan and R'R' stands for white; as well as B stands for bucking, which is dominant over b which is easy riding, what will be the chance of getting a white, bucking horse from a cross between 2 roan, heterozygous bucking horses? 1/8 3/16 1/16 1/4

In rabbits, black hair is due to a dominant allele B and brown hair to its recessive allele b. Short hair (H) is dominant to long hair (h). Show punnet squares In a cross between a homozygous black, longhaired rabbit and a brown, homozygous shorthaired one, what would the F1 generation look like? If you did not know the genotype of an F1 rabbit, you could determine its genotype by a test cross in which it is crossed with an animal with which phenotype AND genotype? If you carried out this test cross (from 2, using the F1 from 1), what phenotypes and in what ratio would you expect? What phenotypes in what ratio would be expected in the F2 generation of the cross in point 1?
In humans, brown eyes are dominant to blue eyes, and the ability to roll your tongue is dominant to not being able to roll your tongue. If a mother who was heterozygous for eye colour and homozygous recessive for tongue rolling had a baby with a father that was heterozygous for both traits, what is the probability that their child would have blue eyes and could roll their tongue?
If a homozygous green leaf is represented by YY and a homozygous yellow leaf is represented by yy, what is the correct phenotype of the following alleles: YY, Yy, yy, Yy (in order)? A)Green, Green, Yellow, Green B)Green, Yellow, Green, Yellow C)Yellow, Yellow, Green, Yellow D)Yellow, Green, Green, Green
In rabbits, black hair is due to a dominant allele B and brown hair to its recessive allele b. Short hair (H) is dominant to long hair (h).

In rabbits, black fur (F) is dominant to white fur (f). You decide to cross a rabbit that is homozygous dominant for fur color with a rabbit that is heterozygous for fur color. Set up a Punnett Square for this cross and then answer the following questions. What percentage of offspring will have the FF phenotype?What percentage of offspring will have the ff phenotype?What percentage of offspring will have the Ff phenotype?
You decide to breed a pair of guinea pigs, one black and one white. In guinea pigs, black fur is caused by a dominant allele (B) and white is due to homozygosity for a recessive allele (b) at the same locus. Your guinea pigs have seven offspring, four black and three white. What are the genotypes of the parents? Why is there a 1:1 ratio in this cross?
Imagine that you are performing a cross involving seed color in garden pea plants. What traits would you expect to observe in the F1 offspring if you cross true-breeding parents with green seeds and yellow seeds? Yellow seed color is dominant over green. a. only yellow-green seeds b. only yellow seeds c. 1:1 yellow seeds:green seeds d. 1:3 green seeds:yellow seeds
A walnut comb rooster is mated to three hens. Hen A, which has a walnut comb, has offspring in the ratio of 3 walnut to 1 rose. Hen B, which has a pea comb, has offspring in the ratio of 3 walnut to 3 pea to 1 rose to 1 single. Hen C, which has a walnut comb, has only walnut comb offspring. What are the genotypes of the rooster and the three hens?
Figure 8.10 In pea plants, purple flowers (P) are dominant to white (p), and yellow peas (Y) are dominant to green (y). What are the possible genotypes and phenotypes for a cross between PpYY and ppYy pea plants? How many squares would you need to complete a Punnett square analysis of this cross?
Gregor Mendel discovered the basis of heredity with his sweet pea plant experiments. In his studies, he determined that certain traits, such as pod color and pea shape, express complete dominance. A cross occurs between a plant with heterozygous yellow pods and wrinkled peas and a plant with green pods and heterozygous round peas. What is the probability that the offspring will exhibit recessive genes for both traits? A - 1/2B - 1/4C - 1/8D - 1/16
