Answer:
40 individuals
Explanation:
The homozygous recessive percentage is equal to q2.
Recessive genotype frequency, q 2 is 1/1000000 = 0.000001
therefore, q = 
= 
= 0.001 = allele "a" frequency
and p + q = 1, thus, p = 1 – q = 1 – 0.001 = 0.999
thus, the frequency of allele a = q = 0.001 and the frequency of allele A = p = 0.999
Carriers are heterozygous and are equal to 2pq.
So, 2pq = 2 x 0.999 x 0.001 x 20,000 = 39.96 (round of to 40)
Hence, 40 individuals will be expected to carry the recessive allele.
Answer:
Here is some background information...
Explanation:
Leeuwenhoek (1633-1723) used melted glass balls to form lenses for apparently crude simple microscopes that nevertheless magnified up to 275 times! Modern tests have concluded that he could have achieved a resolution of two micrometres.
Answer:
Mark thinks Karen is trying to represent the democratic type of parent.
Explanation:
Karen did not impose that Daniel keep playing tennis, which indicates that she is not trying the authoritarian style of parenting. Furthermore, she is not failing to care whether or not Daniel will stop playing tennis, which indicates that she is not trying the negligent parenting style.
However, Karen preferred to explain to Daniel that playing tennis is a beneficial activity and that she is helping him to stay on the team, which made Daniel reason and realize that she was right. This is an example of the democratic type of parentability, where countries explain their opinions on a particular topic, but allow their children to make their own decisions, without imposing reprisals, and without acting as if they don't care.
Not rounded:
0.005% of 100 = 0.005
Rounded to maximum 2 decimals:
0.005% of 100 ≈ 0.01
0.004% of 100 = ? ... 0.006% of 100 = ?
1% of 100 = ?
The answer that makes the most sense is number one or two. Number 3 and number four both makes no sense in that context. Most of the time an animal will not die or mutate due to a parasite in its body.
