A population of ground mice consist of 500 individuals. You are interested in the gene that codes for for a color and find out t
Lelechka [254]

Answer:

0,58

Explanation:

Mice are diploid (2n) organisms, which means that their cells contain two complete sets of homo-logous chromosomes (i.e., they have two copies of any given <em>locus</em>/gene). An allele can be defined as a variant of a gene, whereas diploid (2n) organisms have two alleles at each genetic <em>locus</em>, which are located on homo-logous chromosomes. In this case, we know that there are 580 dominant alleles in a population of 500 individuals, thereby the total number of alleles in this population is 1000 (2n >> 500 x 2 = 1000 alleles), and the frequency of the dominant allele is 0,58 (580/1000 = 0,58).

Carson divided 40 unripe bananas evenly among eight paper bags and sealed the bags. He poked 20 small holes in four of the bags
olga2289 [7]

Answer:

See the answer below

Explanation:

From the illustration of the experiment, the question that Carson can best answer  is that<em> "Do bananas develop more brown spots if they are kept in bags with holes  compared to bags without holes?"</em>

The independent variable in the experiment is the hole poked in the bags while the dependent variable is the number of brown spots on each banana. The difference between the subjects is the hole poked in the bags, hence, any difference in the number of brown spots between bananas in the bags with holes and those in the bags without holes can be attributed to the hole poked in the bags.

<u>Therefore, the question that can be answered from the experiment is to see if poking holes in bags make bananas to develop more brown spots compared to bags without holes. </u>
