Answer:
- Half (8/16) of the offspring will have gray fur and black eyes.
- Half (8/16) of the offspring will have gray fur and red eyes.
- None (0/16) of the offspring will have white fur.
Explanation:
For the purposes of this question, we will assume the following notation for the involved alleles:
G: gray fur (dominant), g: white fur (recessive).
B: black eyes (dominant), b: red eyes (recessive).
A GGbb rabbit may only produce one type of gametes, namely Gb.
A ggBb rabbit may produce either gB or gb gametes.
Since not all theoretical combinations are present, the resulting Punnett square may be simplified as follows:
| Gb
——-+-————
gB | GgBb
——-+-————
gb | Ggbb
As seen above, 100% of the offspring will have a Gg genotype (resulting in gray fur). As for eye color, half of them will have a Bb genotype (resulting in black eyes) whereas the other half will have a bb genotype (red eyes).
Answer: Genetic variation describes naturally occurring genetic differences among individuals of the same species. Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. New genetic variation can be created within generations in a population, so a population with rapid reproduction rates will probably have high genetic variation. And there are the reasons.
The answer is graded potential<span>. Its made of various action potentials that depolarise the neuron incrementaly, in short interspersed intervals that do not give time for the neurons to return to resting potential. Therefore, the actions potentials, of varying sizes, grade up in sum and when they cumulatively reach the threshold level, they invoke an impulse in the nerve</span>
The answer for this question would be B
