Consider a population of 425 diploid giant Sequoia trees. In this population, you observe the following genotypic counts: 100 ho
Lemur [1.5K]

Answer:

q = 0.42

Explanation:

This question is an example of Hardy-Weinberg question and there are two equations necessary to carry out this question;

p + q = 1

p² + 2pq + q²  = 1

where;

p = the frequency of the dominant allele

q =  the frequency of the recessive allele

p² = the frequency of individuals with homozygous dominant genotype

2pq  = the frequency of individuals with heterozygous genotype

q² = frequency of individuals with the homozygous recessive genotype

Since the total  population = 425

q² = \frac{individuals with recessive genotype}{Total Population}

= \frac{75}{425}

q² = 0.1765            

To find q; we need to square root both side to           eliminate the square from  q².

∴ \sqrt{q^2}=\sqrt{0.1765}

q = 0.4201

q = 0.42       (to two decimal places)

How many rounds of replication does it take for an incorporation error to be established as a base pair change?
iris [78.8K]

Answer:

Just one round without DNA repair

Explanation:

When an error occurs before or during replication, in a normal system, there is always proofreading and correction. If the error is not corrected during replication, it can then be corrected by the DNA damage repair system. But if not also corrected, the error becomes fixed and subsequent replication will produce this error
