D - The organisms on the island are slightly different than those on the mainland.

The reason why this is the correct answer is because each successive generation on the mainland as well as the island both develop and continue adapting to their specific ecological niche and environment. They are, howerer, both still part of the same species.

True or false? The absence of a trait cannot be used as a synapomorphy in phylogenetic analysis, only shared derived traits that

Cerrena [4.2K]

Answer:

This statement is False.

Explanation:

A shared apo-morphy which differentiate a clade from other organisms is called synapomorphy. In simple words, members of monophyletic group shares an apomorphy which indicate the presence or absence of certain organs from clade.

For example, loss of legs in snakes is an important synapomorphy.

In a population of Mendel's garden peas, the frequency of the dominant A (yellow flower) allele is 80%. Let p represent the freq

DENIUS [597]

Answer:

If the frequency of the dominant allele in the pea population is 0.8, the genotype frequencies in the population would be 0.64 AA, 0.32 Aa, and 0.04 aa.

Explanation:

Hardy-Weinberg equation tells us that:

p2 + 2pq + q2

p2 is the frequency of AA plants

2pq is the frequency of Aa plants, and

q2 the frequency of aa individuals.

A allele in the population is 80%, the frequency is 0.8.

p represent the frequency of A allele. p is 0.8

Therefore calculating for q ( frequency of a allele).

p + q = 1.0

q = 1.0 − p

q = 1.0 − 0.8

q = 0.2

p = 0.8, q = 0.2.

Now we can calculate the predicted frequencies of the different genotypes, remembering that p2 is the frequency of the AA genotype, 2pq is the frequency of the Aa genotype, and q2 the frequency of aa genotype.

p2 = 0.8 x 0.8 = 0.64

2pq = 2 x 0.8 x 0.2 = 0.32

q2 = 0.2 x 0.2 = 0.04.

Thus, we would expect to see genotype frequencies of 0.64 AA, 0.32 Aa, and 0.04 aa in the pea plants.
