The answer is 0.43
To calculate p we will use one of two formulas of the Hardy-Weinberg principle:
p² + 2pq + q² = 1 and p
+ q = 1
where:
p - the frequency of the allele for long legs which is a dominant trait.
q - the frequency of the allele for short legs which is a recessive trait.
p² - the frequency of dominant homozygote (with long legs)
2pq - the frequency of heterozygote (with long legs)
q² - the frequency of recessive homozygote (with short legs)
So, 33 of 100 organisms have short legs. The frequency of recessive homozygote is represented by q²:
q² = 33/100 = 0.33
⇒ q = √0.33 = 0.57
Using the formula:
p + q = 1
p = 1 - q = 1 - 0.57 = 0.43
Therefore, p = 0.43
substance formed by the chemical combination of two or more elements in definite proportions (a thing that is composed of two or more separate elements; a mixture.)
Answer: the xylem and phloem
Explanation:
During this lining up, DNA sequences can be exchanged between the homologous chromosomes. This type of genetic recombination is called crossing over, and allows the daughter cells of meiosis to be genetically unique from one another. Crossing over can only occur between homologous chromosomes.
