If a single mutation turns off the growth of some pairs of legs within an organism, what's most likely affected?

Answer is A. A Hox gene

Hox genes are a series of genes that controls the differentiation of cells and tissues in an embryo by turn on and off other genes. If Hox genes express incorrectly, a major changes in the morphology of the individual can be seen.

Let’s understand this with an example: The Ultrabithorax, a Hox gene determines the Third thoracic segment in <em>Drosophila melanogaster</em>. Third thoracic segment displays a pair of legs and a pair of reduced wings used for balancing. In the mutant<em> Drosophila</em> the functional Ultrabithorax protein is absent. Due to this mutation, the third thoracic segment now expresses the same structures found on the second thoracic segment, which contains a pair of legs and a pair of wings which are fully developed .

evablogger [386]

Answer:

3) 0.75m/s

Explanation:

The wavelength of a wave is calculated using the formula;

λ = v/f

Where!

λ = wavelength of wave (m)

v = velocity or speed (m/s)

f = frequency of wave (Hz)

According to this question, one end of a rope is vibrated to produce a wave with a wavelength (λ) of 0.25 m and frequency (f) of 3.0 Hz.

Using λ = v/f

v = λ × f

v = 0.25 × 3

v = 0.75m/s.

A population of Drosophila simulans carries three alleles at the white locus: the wild-type allele at 86 percent, w1 at 9 percen
vladimir1956 [14]

Answer:

the population is polymorphic.

Explanation:

Polymorphism is the discontinuous genetic variation that leads to the production of varying unique kinds or forms of individuals within the population of an individual species.

Take for instance, allelic polymorphism is seen in the presence of multiple alleles that is produced within the members of an individual species as in peppered moths, human blood groups, and two-spotted ladybugs.

We have different causes of polymorphism: polymorphism can be sustained by an equity among variation developed by new mutations and natural selection. Genetic variation might be due to frequency-dependent selection.

Which of the following is true about the inheritance pattern of a sex-linked trait?
bonufazy [111]
D. One sex has a higher chance to inherit it than the other (male).

These can be either recessive or dominant. We usually think more of the recessive traits like color blindness and hemophilia but dominant sex-linked traits also exist (fragile X).

What would happen if cytokinesis did not occur?
12345 [234]

Answer:

Cytokinesis takes place in both meiosis and mitosis and performs the separation of he cell in half and form one nucleus into each daughter cell.

If cytokinesis did not happen, it will from multinucleated cells which means that their will be multiple nuclei in single cell and cell will not get separate in half, and no new daughter cells will form.
