plant species A has two alleles for leaf color. if plant species B has four alleles for leaf color, how will the two species dif
Yanka [14]

Plant A would have one allele from each parent, so the leaf color will be the dominant one.

Plant B would have a more complex percentage for traits. And it'll probably "cancel-out" some alleles only showing the info given in one of them.



Hope it helped,

In one generation, the frequency of the A allele is 70 percent and the frequency of the a allele is 30 percent. What are the cha
Fynjy0 [20]
The answer is 9%.

To calculate this we will use some <span>formulas of the Hardy-Weinberg principle:
</span><span>p² + 2pq + q² = 1 and <span>p + q = 1
where:
</span></span>

<span>p - the frequency of the A allele.
q - the frequency of the a allele.</span>

p² - the frequency of dominant homozygote (with AA genotype)

2pq - the frequency of heterozygote (with Aa genotype)

<span>q² - the frequency of recessive homozygote (with aa genotype)</span>

<span>We know:</span>

p = 70% = 70/100 = 0.7

q = 30% = 30/100 = 0.3

We need to calculate the frequency of the genotype aa:

q² = ?

Since we know the frequency of allele q, it is easy to calculate the frequency of the genotype aa:

q² = 0.3² = 0.09 = 0.09 · 100% = 9%

When a drug is discontinued, what percentage of that drug will remain in the body after three half-lives?
777dan777 [17]

Answer:

About 12.5%

Explanation:

Every half life usually eliminates about half or 50% of drugs that is stored in the body system.

Therefore, after one half life, the percentage of drug stored in the body will be 50%, after two half lives it will be reduced by 50% which is 25%.

After three half lives, the percentage of drug stored in the body will also be eliminated by 50% which will be half of 25% and it will be 12.5%.

Therefore, the answer is 12.5%.
