The frequency of carriers for a rare autosomal recessive genetic condition is 0.04 in a population. Assuming this population is
sertanlavr [38]

Answer:

E

Explanation:

Hardy-Weinberg principle states that frequency of alelle and genotype will remain constant in the absence of genetic disturbances such as mutation, no change in the DNA sequence, the population must be large and others

the principle is defined by the equation

p² + 2pq + q² = 1

where the frequency of the dominant allele is p, and the frequency of the recessive allele is q. Going by the what is given which is for the carriers is 0.04 = 2pq

substitute the value into the expression

p² + 0.04  +  q² = 1;  The information is not enough to calculate either p or q going by the equation generated.

The endosymbiotic theory proposes that eukaryotic cells arose as a result of large cells engulfing smaller, aerobic bacteria. th
lina2011 [118]

The organelle that provides evidence for this theory is the mitochondria and the chloroplast.

<h3>What is the endosymbiotic theory?</h3>

The endosymbiotic theory is the theory which describes how the eukaryotic cells arose from simple prokaryotic cells.

In the endosymbiotic theory states that when two prokaryotic cells with several abilities came together, one engulfed the other and existed in a symbiotic relationship that enabled  the cells to meet their needs for survival an growth.

The mitochondria and the chloroplast provides evidence for the endosymbiotic theory.

In conclusion the endosymbiotic theory describes  how eukaryotic cells arose from simple prokaryotic cells.
