Question

A sample of 500 field mice contains 225 individuals that are D₁D₁, 175 that are D₁D₂, and 100 that are D₂D₂.

Is inbreeding a possible genetic explanation for the observed distribution of genotypes? Why or why not?

Accepted Answer

Hello, everyone and welcome to today's video. So straight whiskers are a dominant trait in rabbits where curly whiskers are a recessive trait in a small population of 200 rabbits, eight of them have curly whiskers. The term Q two for this population or Q square for this population. So answer choice A, we have 0.4 as answer choice B, we have 0.8 as answer choice C we have 0.2 and as answer choice D we have 0.4. Well, when they're asking this question to the term in Q two, they're asking for the genotype frequency of the Homo Sagas recessive traits, which in this case, is stated to be curly whiskers. Well, thankfully, we're going to be able to solve this problem without using the Hardy Weinberg equation because it is stated that eight out of 200 rabbits are going to have curly whiskers. So we only need to divide the number of rabbits with curly whiskers by their total number of rabbits or eight divided by 200. When we perform this division, we're going to obtain the correct answer choice or the result is going to be 0.4, which is represented by answer choice 80.4. That's or Q squared for this problem. I really hope this helped you and I hope to see you on the next one.
