Answer:  C. Capillaries.

When one allele is dominant to another, what is the most common biological mechanism for this dominance?
MAVERICK [17]

Answer:

A. Dominant alleles often encode functional products, whereas recessive alleles often do not encode functional products

Explanation:

One gene can have it's variant forms called allele but in one individual only two allele form of a gene can be present. These two allele form can be the same(homozygous) or different(heterozygous). A dominant allele often encode a function protein of product while recessive allele often code for non- functional product.

Therefore when the dominant allele is present in the chromosome then function products are formed which can be seen in the phenotype and even a single dominant allele produce the functional product like in heterozygous condition so phenotype in heterozygous and homozygous dominant condition appears same. So the correct answer is A.

Lena [83]

Answer:

No, observed and expected frequencies are different.

Observed frequencies: p2 = 0.56 , 2pq = 0.375, q2 = 0.062

Expected frequencies: p2 = 0.774 , 2pq = 0.211, q2 = 0.014

Explanation:

Given frequency of recessive genotype (q2)= 14/ 1006 = 0.0139

Frequency of recessive allele s (q) = square root of 0.0139 = 0.12

Frequency of dominant allele S (p) = 1-q = 1-0.12 = 0.88

Expected frequency of homozygous recessive genotype = 0.12 x 0.12 = 0.014

Expected frequency of homozygous dominant genotype = 0.88 x 0.88 = 0.774

Expected frequency of heterozygous dominant genotype = 2pq = 2 x 0.88 x 0.12 = 0.211

Observed frequencies in population 2

Observed frequency of homozygous dominant genotype = 308 / 549 =0.56

Observed frequency of heterozygous dominant genotype = 206 / 549 =0.375

Observed frequency of homozygous recessive genotype = 34 / 549 =0.062

Observed frequencies do not match with expected frequencies.
