Aspecies of rodent can either have brown fur or white fur. brown fur is recessive and white fur is dominant.
which of the following would cause the rodent population to not be in hardy-weinberg equilibrium?
brown fur allows rodents to hide more easily.
white fur attracts mates better.
rodents cannot leave or enter their habitat.
the rodents mate randomly.
the rodents mutate a new allele for gray hair.

Answer : The correct answer is -

The rodents mutate a new allele for gray hair.

A population is said to be in the Hardy Weinberg equilibrium when it follows the following five conditions -

1) There should be no mutation.

2) No gene flow should be there in the population.

3) Population size should be large.

4) There should be random mating in the population.

5) No natural selection should operate on the population.

According to this information, we can conclude that last option in the question will cause the rodent population not to be in the Hardy Weinberg equilibrium.

its 42

i say its d?

i think a) betsy can donate only blood to mark is correct because, mark and betsy have the same blood type. whereas nobody else has b+ blood so betsy can't donate to them.
