When Mating Two Heterozygotes for Alleles in Which One Is

question 41

Multiple Choice

When mating two heterozygotes for alleles in which one is dominant to the other, if the usual Mendelian segregation process is occurring, the ratio of the offspring phenotypes produced should be 3:1. The dominant phenotype would be more common than the recessive one. Imagine a situation in which two heterozygotes are mated and among their 200 offspring, 160 show the dominant phenotype while 40 show the recessive phenotype. What is the P-value of a two-sided binomial test using the normal distribution to approximate the binomial?

• A) 0.015
• B) 0.031
• C) 0.060
• D) 0.121
