Yes, the different frequencies of evolutionary change could affect allele frequency in a population.

<h3>What are the agents of evolutionary change? </h3>

All populations are usual in a constant state of evolution. This means that all the species are continuously changing their genetic makeup over different generations. These changes can be subtle or they can be spontaneous.

If a population is not evolving, it is said to be in Hardy - Weinberg state. In this state, the allele frequency and the genetic makeup of the population will remain the same across generations.

The agents of evolutionary change defy the Hardy - Weinberg state. These are mutation, gene flow, non-random mating, natural selection and genetic drift.

Answer:

Zero (0)

Explanation:

According to the given information the genotype of the woman with blood type "AB" would by I^AI^B. The genotype of the man with blood type O would be "ii". Here, the alleles I^A and I^B are dominant over the allele "i".

A cross between parents with genotype I^AI^B and ii would give 50% of children with I^Ai genotype and 50% of children with I^Bi genotype. The children with "I^Ai genotype" would have blood type "A" and the children with I^Bi genotype would have blood type "B". This couple is never likely to have any child with blood type "O" since the mother does not carry allele "i".

Cross: I^AI^B x ii = 1/2 I^Ai : 1/2 I^Bi

Chloroplasts and mitochondria are both involved in energy conversion in cells. Select the other similarity they share. Question

Afina-wow [57]

Chloroplasts and mitochondria are similar in the sense that they both contain DNA.

MITOCHONDRIA AND CHLOROPLAST:

Mitochondria is a membrane bound organelle found in eukaryotic cells. Mitochondria is the energy production site of cells because it is where cellular respiration takes place.

Chloroplast is another membrane-bound organelle in eukaryotic cells. They are the site of photosynthesis in plants.

Mitochondria and chloroplast are both involved in energy conversion in cells because electron transport chain occurs in both organelles.

However, another similarity between these two organelles is that they contain extra-chromosomal DNA.

The production of hcl is encoded into our dna. using the functions of activators and repressors, explain how hcl is only produce

sashaice [31]

Activators and repressors are transcription-control elements that are found in eukaryotic organisms. These elements function during the process of transcription, where a DNA molecule is coded onto a RNA molecule for it to be sent to ribosomes outside of the nucleus and then polypeptide chains are produced from it.

The activators and repressors control which proteins are made, which means that they can either hinder or promote certain functions in the cells of the body. Therefore, even though all of the cells have the same set of DNA, some are able to produce HCl, while others produce other substances such as insulin.
