Question
In peas, Y produces yellow seeds and is dominant over y, which produces green seeds. R produces round seeds and is dominant over r, which produced wrinkled seeds.
If a YyRr individual mates with a yyRr individual, the expected progeny will be: 3/8 yellow, round; 3/8 green, round; 1/8 yellow, wrinkled; 1/8 yellow, wrinkled
In the above cross, you generate 100 offspring, and observe the following phenotypes: 25 yellow, round; 27 yellow, wrinkled; 22 green, round; 26 green, wrinkled
Perform a Chi-squared tet to determine whether the hypothesis of independent assortment can be rejected.
?(observed-expected)2 / expected
Be sure to indicate the chi-square value AND the p-value, and indicate whether the null hypothesis can be rejected.
Explanation / Answer
In peas, Y produces yellow seeds and is dominant over y, which produces green se
