What might modern scientists learn from examining evidence collected by earlier investigators

1 answer:

3 0

Earlier investigators collect and note as much information about the artifacts. The idea is that based on the results previously obtained 1) you should be able to reproduce the same results if a modern scientist does the experiment again. 2) The results obtained can be used to develop new ideas or concepts and even better technology. Moreover, modern scientists are able to take on the idea that sometimes we don't need to rely on fancy equipment to get answers.

e) The allele for small size is recessive, and the allele for normal size is dominant. The frequency for the normal-size allele

ki77a [65]

Answer:

51.84%

Explanation:

p² + 2pq + q² = 1 and p + q = 1

p = frequency of the dominant allele in the population

q = frequency of the recessive allele in the population

p² = percentage of homozygous dominant individuals

q² = percentage of homozygous recessive individuals

2pq = percentage of heterozygous individuals

p = 0.72 => p² = 0.72² = 0.5184

=> Percentage of the rats are normal sized: 51.84%
