Explain in 3-4 sentences: How can a population's gene pool can change?​

Biology
1 answer:
avanturin [10]2 years ago
4 0

Answer:

The composition of a population's gene pool can change over time through evolution. This can occur by a variety of mechanisms, including mutations, natural selection, and genetic drift. The result is a gene pool that is altered to be attuned to the needs of the population's specific environment.

Select the correct answer from each drop-down menu. what are the four types of nitrogen bases of dna nucleotides? the four types
Hitman42 [59]

The four types of nitrogen bases of dna nucleotides are:

  1. Adenine (A)
  2. Cytosine (C)
  3. Ganine (G)
  4. Thymine (T).

These bases form specific pairs (A with T, and G with C).

<h3>What is DNA nucleotides?</h3>

Nucleotides can be defined as those organic substances consisting of a nucleoside and a phosphate.

They serve as monomeric units of the nucleic acid polymers –

  • Deoxyribonucleic acid
  • Ribonucleic acid,

So therefore, the four types of nitrogen bases of dna nucleotides are:

  • Adenine (A)
  • Cytosine (C)
  • Ganine (G)
  • Thymine (T).

Each genetic outcome of a genetic cross between the same parents is ______ all previous outcomes. multiple choice question.
tino4ka555 [31]

A genetic outcome of a genetic cross between the same parents is independent of previous outcomes.

<h3>What is genetic variation?</h3>

Genetic variation can be defined as the genetic poll of an organism, which is the raw material trough which evolution can occur by natural selection.

During sexual reproduction, the formation of gametes generates different genetic backgrounds which are independent of distinct gametes.

In conclusion, each genetic outcome of a genetic cross between the same parents is independent of all previous outcomes.
