Answer: to predict the probability of offspring genotypes
Explanation: Punnett squares are developed to predict the probability of offspring genotype. Punnett square is a square shaped diagram used for predicting the possible genotypes of a cross between two organisms. Punnett square is named after Reginald C. Punnett, who invented the approach. In punnett squares, the genotypes of the parents are written on the top and left hand side of the square while the possible genotypes of their offsprings are written in the boxes.
Answer:
Paul has natural active immunity, while Nicholas has artificial active immunity.
Explanation:
Natural active immunity is an immunity that occurs when an individual is exposed to a disease causing organism, gets infected, and also become immune to the disease due to the primary immune response. From the question, Paul has natural active immunity because he had chicken pox before, and the virus that causes chicken pox has interacted with his immune response, hence, making him to develop natural immunity to the disease.
Artificial active immunity is an immunity that an individual acquires when small amount of immunity to a disease is deliberately exposed to his body. Artificial active immunity is usually produced in the form of vaccinations. From the question, Nicholas has artificial active immunity because chicken pox vaccines were intentionally introduced to his body.
Answer:
mitochondrion / mitochondria coming from the apex.
Answer:
The correct answer is: c) usually produces offspring that cannot reproduce.
Explanation:
Hybridization, also knowns as selective breeding, is an <u>artificial process</u><u> that involves selecting parents with specific characteristics in order to obtain an offspring with the same traits</u>.
Hybridization is very common and has been performed by humans for thousands of years: from selective breeding crop plants, to do so with dogs in order to create more desirable breeds.
Option A is incorrect because hybridation does not occur in nature, it is an artificial process.
Option B is incorrect because hybridation often happens when the selected parents are chosen to reproduce (by a human).
Option D is correct because an important amount of hybrids are sterile (for example: mules).
Option D is incorrect as well because the offspring is not identical: it shares a combination of genes from both parents.
