In peas, yellow seed pod (Y) is dominant to green seed pod (y), and inflated seed pod (N) is dominant to constricted seed pod (n). These two loci are NOT linked.

A true-breeding pea plant with yellow, inflated pods is crossed to a true-breeding plant with green, constricted pods. The F1 progeny are self-fertilized.

What is the probability of obtaining a plant that produces yellow, constricted seed pods in the F2?

In garden peas, inflated pod shape (I) is dominant to pinched pod shape (i) and yellow pea colour (Y) is dominant to green (y) pea colour. Plants heterozygous for these characteristics were selfed (note that this is not a test cross), and the following numbers of phenotypes were seen in the progeny: 556 inflated, yellow; 193 inflated green; 184 pinched, yellow; 61 pinched green Test the data for the involvement of two independently assorting genes using the Chi-square test (don’t...

In peas, tall (T) is dominant to short (t), yellow (Y) is dominant to green (y) and round (R) is dominant to wrinkled (r). A purebreeding plant with tall, green and wrinkled pea phenotypes is crossed to a purebreeding plant that is short and makes yellow, round peas. When peas from this F1 generation are crossed, what is the probability of obtaining a short plant that makes yellow, wrinkled peas in the F2?

Pod characteristics are effected by a number if genes. Pod color (green dominant to yellow), pod surface (rough is recessive to smooth), and pod width (wide is dominant to narrow). Pod color and pod surface are 10 map units away. True breeding plants with green, wide, and smooth were mated with yellow, narrow, and rough. This plant was test crossed. If 1000 testcross progeny were examined, how many are expected to have yellow, wide, and rough pods?

Question 1 Yellow seed color is dominant to green seed color. A green seeded plant is crossed with a heterozygous plant. What phenotypic and genotypic ratios would you predict in the offspring? If I planted 200 of these offspring, how many would be green? How many would be yellow? Explain how you solved the problem.

A genetic experiment involving peas yielded one sample of offspring consisting of 409 green peas and 140 yellow peas. Use a 0.05 significance level to test the claim that under the same circumstances, 23% of offspring peas will be yellow. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method and the normal distribution as an approximation to the binomial distributionWhat are the null...
