1. Two homozygous strains of white-flowered bluebonnets are mated, the F1 offspring all have white flowers. The F1 plants are crossed to each other, 126 white-flowered and 33 blue-flowered plants were produced. Which of the following best describes the genotype of a homozygous blue-flowered plant?

A/A; B/B

A/A; b/b

a/a; b/b

A/A; b/b or a/a; b/b

there are not enough data to tell

2. From the F2 offspring in Question1, you cross two white flowered plants to each other. Half of their offspring have white flowers and half have blue flowers. What are the genotypes of the two white-flowered F2 plants?

A/A; B/B and a/a; b/b

A/A; b/b and a/a; B/b

a/a; b/b and A/A; B/b

A/A; b/b and A/a; b/b

Two pea plants are crossed. One is homozygous for white flowers and the other is heterozygous for purple flowers. Both are heterozygous for being tall plants. In pea plants, tall is dominant to short, and purple flowers are dominant to white. Fill out the table below for the probability of each possible phenotype. Report probability as a decimal rounded to four places (e.g. 0.1250, not 1/8 or 12.5%). Phenotype Probability tall purple __________ short purple __________ tall white __________ short...

In a breeding experiment, chicken with white feathers, small comb were mated and the 192 offspring belonged to four categories are (i) white feathers, small comb (WS) – 100 offspring, (ii) white feathers, large comb (WL) – 32 offspring, (iii) dark feathers, small comb and (DS) – 40 offspring, (iv) dark feathers, large comb (DL) – 20 offspring. Use an appropriate test to check if the offspring categories follow the expected ratio 9:3:3:1 (level of significance = 0.05).

Two purple sea slugs are mated with each other. Among their numerous offspring, 428 have a purple integument and 152 have orange integuments. With a chi-square test, compare the observed numbers with a 3:1 ratio and determine if the difference between observed and expected could be a result of chance.

Two pink-flowered azaleas are crossed. The cross produces are 25 pink, 13 white, and 10 lavender-flowered plants. The color trait could be monogenic with incomplete dominance (1:2:1) or digenic with epistasis (9:4:3). What statistical test could you perform to test this hypothesis? Does this test actually allow you to distinguish between these hypotheses? Explain and show your calculations. Note: A p-value of 0.05 equals 5.99 equals for two degrees of freedom.
