You are studying two genes in Loraxes - Gene A and Gene B
Subject:BiologyPrice: Bought3
You are studying two genes in Loraxes - Gene A and Gene B. Both genes have two alleles (A and a; B and b) in a dominant recessive relationship; phenotype A is dominant to a; phenotype B is dominant to b.
You cross two loraxes, both heterozygote for A and B, and find the following among their offspring:
- 347 phenotype A, B
- 22 phenotype a, B
- 21 phenotype A, b
- 97 phenotype a, b
Note: offspring with "phenotype A, B" means they have the dominant phenotype for A and the dominant phenotype for B, while "phenotype a, B" would mean they have the recessive phenotype for A and the dominant phenotype for B; and so on.
Perform a Chi-square test to determine if your observations match what you'd expect from typical mendelian inheritance.
What is your X2 value?
Do your results differ significantly from what you'd expect (assume a significance level of 0.05; in other words, p < 0.05 = significant)? In your answer make sure to indicate your p-value.
