Two gene loci, A and B, are on separate chromosomes and alleles A and B are dominant over alleles a and b. A codes for long branches, a codes for short branches. B codes for green leaves and b codes for blue leaves. A branch diagram or a punnett square would be useful for you to work this problem. What percentage of the progeny will have short branches and blue leaves from a cross AaBb × Aabb? Group of answer choices 1/8 1/4 1/2 3/4

Imagine that you are performing a cross involving seed texture in garden pea plants. You cross true-breeding round and wrinkled parents to obtain F1 offspring. Which of the following experimental results in terms of numbers of plants are closest to what you expect in the F2 progeny? a. 8lOroundseeds b. 8lOwrinkledseeds c. 405:395 round seeds:wrinkled seeds d. 610:190 round seeds:wrinkled seeds
A cross was made between two pea plants, TtAa and Ttaa, whereT = tall, t = dwarf, A = axial, and a = terminal. What is the probability that the first three offspring will be tall with axial flowers or dwarf with terminal flowers and the fourth offspring will be tall with axial flowers? Discuss what operation(s) (e.g., product rule or binomial expansion equation) you used and in what order they were used
In corn plants, a dominant allele Z inhibits kernel color, while the recessive allele z permits color when homozygous. At a different locus, the dominant allele X causes purple kernel color, while the homozygous recessive genotype causes red kernel color. If corn plants heterozygous for both the Z and X genes are crossed, what are the chances that the offspring will have purple kernels? Enter your answer as a decimal fraction in the box (e.g. 0.25).
If a cross is made between two plants that are heterozygous for two traits (AaBb), then their offspring should follow the 9:3:3:1 ratio. In this case, A is the dominant allele for purple leaves, and B is the dominant allelle for curly roots. If the two parents were crossed to yield 320 progeny, approximately how many plants with purple leaves and curly roots would you expect? Group of answer choices a.180 b.225 c.25 d.50 As part of a lab experiment, you create a two-locus cross between two plants, and you expect to see a 8:4:2:2 ratio of offspring. You determine the phenotype for 160 offspring, and find the proportions 84:38:19:19. If you use a chi-square test to determine whether the offspring do indeed fit this pattern, how many degrees of freedom would the test have? Group of answer choices a.2 b.3 c.83 d.4
In pea plants, purple flowers (P) are dominant to white flowers (p) and yellow peas (Y) are dominant to green peas (y). What are the possible genotypes and phenotypes for a cross between PpYY and ppYy pea plants? How many squares do you need to do a Punnett square analysis of this cross?
Crossing two green corn plants results in 2/3 green progeny and 1/3 white progeny. If you cross 2 green progeny with each other, your expected phenotypic ratio is: The correct answer is 2 green and I white, but I don't know why.
You crossed two true-breeding lines of violet-flowered and white-flowered peas. Is it possible to establish a true-breeding line of the genotype found in the offspring of your cross? Why or why not?
In snapdragons, heterozygotes for one of the genes have pink flowers, whereas homozygotes have red (R) or white (r) flowers. When plants with red flowers are crossed with plants with white flowers, what proportion/probability of the offspring will have pink flowers? Create a Punnett square.
Suppose that goats have one gene that codes for color, where A is brown and a is white. The goats also have another gene that codes for height, where B is tall and b is short. If these two genes are unlinked, what is the probability that a cross between Aa Bb × Aa bb parents will produce three out of five offspring that are white and tall? Enter your answer as a decimal, rather than as a percentage

If in an F2 320 pumpkins are obtained, how many of them are expected to be...Yo. white-discordant.ii. white-spherical.iii. green-discoidiv. green-spherical.b. If you cross a BbDd plant with a double recessive one and you get 100 pumpkinsWhat proportions do you expect to obtain from each of the following phenotypes?1. white-discordant.2. white-spherical3. green-discoids4. green-sphericalc. Based on your answer, are the genes involved in fruit color and shape linked or independent? Because?
A cross between two red flower plants produces 2/3 progeny that are red and1/3 progeny that are yellow. What is the genotype of the red flower? Explain these unexpected ratios.
The crossing of two orange-flowering plants results in ~2/3 orange-flower progeny and ~1/3 white-flower progeny. The crossing of two orange-flowering F1 plants generates the same progeny ratios as observed for the parental cross, while the crossing of white-flowering F1 plants only produces white-flowering progeny. What is a likely explanation for these results?
