Answer:

The correct answer will be option C.

Explanation:

By studying the fossils it has been suggested that human teeth like other bones also evolved with time. These teeth evolved in humans as the food diet of the ancestors changed from eating plants to hunting and eating the meat of other animals.

Human teeth size has generally decreased in size during evolution which is easily observed in the molar teeth or wisdom teeth.  In modern human or <em>Homo sapiens,</em> the wisdom teeth are usually smaller as compared to ancient hominins like<em> Paranthropus boisei </em>or “Nutcracker” that lived 2.3 million years ago with the largest molars. This change developed due to use of the advanced tool by the genus Homo as with the use of tools humans did not have to spend much energy on developing teeth.

Thus, option C is the correct answer.

16. Why should the recessive phenotype be used first to determine the q squared value instead of the dominant phenotype to deter
podryga [215]

The recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.

<h3>What is a recessive phenotype?</h3>

A recessive phenotype is a phenotype which expresses the recessive trait of a gene.

The recessive phenotype is always h0m0zygous for that triat to be expressed.

In the Hardy-Weinberg equilibrium equation, the allele and phenotype frequencies are given as follows:

  • p^2 + 2pq + q^2 = 1

where;

  • p^2 is the h0m0zygous dominant phenotype frequency
  • 2pq is the heterozygous phenotype frequency
  • q^2 is the h0m0zygous recessive phenotype frequency

Therefore, the recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.

If bicoid mRNA is injected at the anterior end of an egg from a bicoid mutant mother, what would the phenotype of the resulting
JulijaS [17]

If the larva had one head at the posterior pole, it would be normal. The larva would have two heads, one at the front of its body and the other in the center.

What is bicoid mRNA?

When translated, bicoid protein forms a morphogen gradient that shapes the embryo's head and thorax if bicoid mRNA localizes to the anterior of the Drosophila egg.

How does the egg's bicoid RNA influence development?

According to recent research, Bicoid specifies the anterior of the Drosophila embryo in two different ways. It initially suppresses posterior development. It accomplishes this by attaching to and preventing caudal RNA, which is distributed throughout the egg and early embryo, from being translated.
