Answer:
3
Explanation:
Heterozygous mice at both loci would be BbAa genotype.
B (black) is dominant over b (white) but the presence of A results in agouti.
Crossing two heterozygous:
BbAa x BbAa
Progeny
<em>9 B_A_ - Agouti</em>
<em>3 bbA_ - agouti</em>
<em>3 B_aa - Black</em>
<em>1 bbaa - white</em>
Hence, 3 out of 16 progeny will be black in color.
<em>See the attached image for the Punnet's square analysis of the cross.</em>
Answer:
if you mean environmental degradation it is where the environment deteriorates(gets worse).
Explanation:
this happens through lack of air,water and soil, destruction of ecosystems and habitat destruction
Answer: For three traits inherited in a dominant/recessive pattern, the probability of an offspring in a trihybrid cross between parents heterozygous for all three traits to be recessive at exactly two of the three loci is 23/64.
Explanation: Let A, B and C represent the dominant alleles and a, b and c represent the recessive alleles. The genotype of each of the parent will be AaBbCc since it has been said to be heterozygous for all the three traits. There are eight (8) possible different types of gametes from each of the genotype. This can be calculated using 2^n where n is the number of heterozygous loci.
The number of heterozygous loci in the genotype AaBbCc is three (3). 2^3 = 8. The gametes are;
ABC
ABc
AbC
Abc
aBC
aBc
abC and
abc.
Therefore, sixty-four possible offsprings are expected from the cross AaBbCc x AaBbCc.
Out of these offsprings, twenty-three (23) are expected to be heterozygous at two loci as boldly shown in the attached image.
Answer:
Option (A) is the correct answer to this question.
Explanation:
If the hypothesis is correct then we shall be higher than Fst in the rest of the genome in the area environment the cold-shock protein in the genomic region surrounding the cold-shock gene, except for the Fst.
- Cold shock components are those product uses that are produced in cold and defend against cold stress. Fst is a gene of ice, present offshore of proteins from cold shock. During cold stress, the fist gene expression increase by several folds to increase cold shock protein production.
- Other options are incorrect because they are not related to the given scenario.
The best answer is; False
Fresh water found in soil and rock layers below Earth’s surface is not called deep water. It is known as ground water. Groundwater is the water that exists below the earth's surface in the cracks and spaces in soil, rock and sand. Groundwater flows to the earth surface naturally and discharges to water bodies such as rivers, lakes and wetlands. Groundwater is usually extracted for municipal, industrial and agricultural uses by extraction wells.
