<span>To have the disease, males need only one copy of the affected X.</span>

So, the frequency of affected males will be the frequency of the disease allele = 0.02

Females must inherit two copies and be homozygotes, so the frequency of affected females will be the double of frequency of the disease allele = (0.02)

Since the ratio between female and male is 50:50 that is half of the population is male and half female

<span>Then the overall frequency of the disease will be,</span>

(0.5) (0.02) + (0.5) (0.0004) = 0.01 + 0.0002

<span>Thus, the frequency of affected individuals in this population is <span>0.0102.</span></span>

The alkanes in petroleum can be partly separated by
Arte-miy333 [17]

Fractional distillation is the process in which the alkanes in petroleum can be partly separated. This is due to the petroleum having different boiling points. The process starts off with the heating of crude oil for it to vaporize. The vaporized crude oil is then fed into the bottom of the distillation tower. The resulting vapor rises through a vertical column. As the gases rises through the distillation tower, its temperature decreases. Thus, certain hydrocarbons begin to condense and run off at varying levels. Each level-specific condensed fraction contains hydrocarbon molecules that has a similar number of carbon atoms. These "cuts" of boiling point allow numerous hydrocarbons to be separated out in a single process. The cooling of the tower height allows for the separation. Subsequent to the refinement, individual fuels may undergo more refinement to remove existing contaminants or substances so as to improve the quality of the fuel through cracking.

aksik [14]

Answer:

The axial filament is located between the cell membrane and the outer membrane.

Explanation:

Axial filaments are structures used for motility too. They wraped around the cell body and are found in spyrochetes. The origin of the flagella is in the periplasmic space, the space between the inner membrane and the outer membrane they differ because other flagellum are near the cell surface, attached to the basal body enclosed in the cell envelope.
