Answer:
Since albinism is an autosomal recessive trait, it means that both parents must possess the gene for it, for the albinism to occur.
Thus, David could be the father if both Rose and David are carriers(heterozygotes) for the albino allele.
<span>Let the equation be : at^2 + bt + c = P,
where t = time (hrs),
P = population (1000's).
When t = 1, P = 3.03.
When t = 2, P = 1.72.
When t = 3, P = 1.17.
Substitute these into the equation to obtain these 3 simultaneous equations :
a + b + c = 3.03
4a + 2b + c = 1.72
9a + 3b = c = 1.17
Solving gives :
a = 0.38,
b = -2.45,
c = 5.1.
The equation is therefore,
P = 0.38t^2 - 2.45t + 5.1
Testing with t = 0 to 6 gives the population values as provided,
so it seems to be a valid model.
At t = 9 hrs,
P = 0.38*9^2 - 2.45*9 + 5.1
= 13.83.</span>
Answer:
The population with the greatest genetic variation may have:
- The greatest number of alleles per gene
- The largest gene pool
Explanation:
A higher number of alleles will produce a higher total number of protein forms per gene. Moreover, the largest gene pool will synthesize the largest content of proteins, thereby increasing variation
Answer:
The discussion allows all group members to share their points of view.
and
The discussion encourages group members with conflicting views to speak up.
Explanation:
A good discussion always clears up everyone's point of view, letting everyone voice their opinion.
