The surviving children would be 66.7% female and 33.3% male. Of the female children, 50% would be expected to be carriers of this gene (like their mother)
| Xg | X
—————-
X | XXg | XX
—————-
Y | XgY | XY
Pretty ugly, but the best punnet square I can do without a link. The offspring with the “g” are those that carry the lethal gene. The male child that carries it will die, but since it is recessive, the female child will live but will be a carrier for this gene. I hope this helps.
Answer:
<h3>Genotype frequencies</h3>
25% DD
50% Dd
25% dd
or
1 DD: 2 Dd: 1 dd
<h3>Phenotype frequencies</h3>
75% Dark brown, 25% light brown
or 3 dark brown: 1 light brown
Explanation:
Two heterozygous parents have the genotypes Dd. Therefore, the cross is Dd x Dd.
D d
D DD Dd
d <em>Dd dd</em>
<em />
25% (1:4) of the organisms have the genotype DD, and therefore the phenotype is dark brown, since it has two copies of the dark brown fur allele (DD)
50% (1:2) of the organisms have the genotype Dd, and therefore, the phenotype is dark brown since dark brown fur (D) is dominant to light brown fur (d).
25% (1:4) of the organisms have the genotype dd, and therefore the phenotype is light brown, since it has two copies of the light brown fur allele (DD)
It's for sure not A because having thick fur will only make you hotter, and thus you will suffer a heat stroke. It's not C because small ears would not be long enough to provide you with cooling. That one does not make sense. It could be D, but the species would need to have alot of muscles in order to be consistently flapping there ears for the constant hear. Answer is B because it is the most logic, and the fewer amount of fur, the less hotter you will be, especially if your fur provides insulation.
Answer is B. Species B because fur would provide insulation.
About 9 of the eggs will be yellow. and the rest will be green.

<em>Given their unique regenerative abilities, stem cells offer new potentials for treating diseases such as diabetes, and heart disease. Research on stem cells continues to advance knowledge about how an organism develops from a single cell and how healthy cells replace damaged cells in adult organisms.</em>
