A population of beetles was scored for color. The frequencies of the genotypes and their relative fitness values are given in the table below.

Genotype: BB Bb bb
Phenotype: Black Brown White
Frequency: .4 .25 .35
Fitness: .75 .85 1

a. This type of selection is best described as . (Pick the best answer)
Directional
Stabilizing
Disruptive

b. The average fitness for color in this population of beetles = .
Please round your answer correctly to 4 decimal digits.

c. You are studying skin color in a population of frogs at Lake Johnson. Your original population of 350 frogs had a green allele frequency of 0.4 and a brown allele frequency of 0.6. An animal rights student group "rescued" 50 lab frog that had a green allele frequency of 0.7 and released them into Lake Johnson where they mixed with your population. The frequency of the green skin allele in the population after migration is.

b is dominant over the allele for the white fur.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).

i wish i could with all of them i can barley see the first one so here's the answer to the first one b

answer: andy garner, a 17-year-old who decided to become a human guinea pig in 1965 and go without sleep for 11 days. by the second day his eyes had already stopped focusing, and he lost the ability to identify objects by touch. by day three he was moody and uncoordinated and by the end he had trouble with short term memory and had even started hallucinating.

and a rare genetic mutation called fatal familial insomnia, where people can’t sleep at all, gets progressively worse over months or years and leads to dementia and death.

a devoted soccer fan died after staying awake 48 hours to watch the world cup, she said. ‘while his untimely death was due to a stroke, studies show chronically sleeping fewer than six hours a night increases stroke risk by 4 1/2 times compared with those getting a consistent seven to eight hours.'
