Answer:

a. bottleneck effect.

Explanation:

A bottleneck effect occurs when some adverse environmental conditions such as typhoons and famine reduce the population size considerably. The allele frequencies of the population are changed. As the population grows again, the gene pool has different allele frequencies than the original population. During population growth, some harmful alleles may become more abundant resulting in a rare disease such as achromatopsia. Therefore, the given population represents the bottleneck effect.

1. Why does the Elodea cell have chloroplasts but the onion cell does not, even though both are plant cells? Please answer quick
Oksanka [162]
Chloroplasts contain chlorophyll which is what makes plants green. Onions are not green because they do not contain chloroplasts. The reason they do not have chloroplasts is because in the chloroplast, photosynthesis takes place. A key player in the process of photosynthesis is the sun. The onion itself grows underground which means while they grow they do not come into contact with the sun so chloroplasts in an onion is pointless since they can’t undergo photosynthesis. Hope I helped!
