Astorm washed five female and five male tiger beetles from the mainland to a small island that had no previous population of tiger beetles. in tiger beetles, having six spots (a) is dominant to having four spots (a). all ten beetles had six spots, but one male and one female were heterozygous for the four-spot trait. if six of the beetles died randomly without reproducing, the ratio of the genotypes could be quite different in subsequent generations. this change in allele frequencies would be an example of:

genetic drift

Explanation:

Genetic drift is one of the basic mechanisms of evolution, along with natural selection, migration and mutations. This mechanism, especially important in small populations, can be defined as a change in allelic frequencies that occurs entirely randomly. Although it also affects the genetic makeup of a population, it differs from natural selection by not producing adaptations.

We can see an example of genetic drift in the above question, since if six of the beetles died randomly without reproducing, the proportion of genotypes could be quite different in subsequent generations and it would be possible to see a change in the allelic frequencies of this beetle population.

c. would be the answer : )

explanation:

the right answer is a. skin cells forming from sunlight.

the liver is an organ endowed with a fantastic ability to regenerate

. thus, if a hepatectomy (ablation) of 70% of the hepatic mass is performed in the rat, there is complete recovery in 7 to 10 days.

prokaryotes are beings that have existed since the existence of life on earth, and do not come from another realm.

ribosomes are organelles that exist naturally in eukaryotes, either in free form or attached to the endoplasmic reticulum.
