The correct answer is allele.
I hope I helped!
Answer:
True
Explanation:
The study of the formation and development of the embryo is very useful in evolutionary biology in order to determine similarities derived from a common ancestor (i.e. homologies). In consequence, embryology is a discipline used to establish relationships between species and higher taxa. For example, vestigial organs and/or tissues (e.g., tails in humans) can be observed in the embryos during the first stages of development. In this regard, embryology has been an important aspect of the evolutionary theory proposed by Darwin (1859) by evidencing the process of species radiation from their ancient ancestors.
<h2>Answer:</h2>
The one condition that must be met for a population to be in genetic equilibrium:
A Large Breeding Population.
<h3>Explanation:</h3>
- A large breeding population helps to ensure that chance alone does not disrupt genetic equilibrium.
- In a small population, only a few copies of a certain allele may exist.
- If for some chance reason the organisms with that allele do not reproduce successfully, the allelic frequency will change.
Answer: The correct answer is- Polymerase chain reaction.
Polymerase chain reaction is a technique in molecular biology that is used to produce multiple copies of a piece of DNA molecule through multiple cycles of three stages that are-
1) Denaturation- The two DNA strands are separated ( so that template DNA are exposed) at higher temperature.
2) Annealing- Primers ( forward and reverse) are attached to the template DNA.
3) Extension- New DNA strand is synthesized using enzyme Taq polymerase that adds dNTPs ( deoxyribonucleoside triphosphate) according to the complementary sequences in the template.
