Explain the specific mechanisms that have allowed for diversity in organisms
kirill115 [55]

There are five mechanisms involve in diversity of organisms:

genetic drift, mutation, natural selection, gene flow and non random mating.

Explanation:

Genetic drift: It is a mechanism in which frequency of the allele changes within a population due to random sampling. It causes decrease in diversity in organism and can result in new species.

Mutation: Mutation in the genes is the most important reason of diversity.the change in DNA causes introduction of new alleles. Harmful mutations do not le species evolve by delimiting them from reaching sexual maturity.

Gene flow: The allele flow happens when a new gene is introduced into a population either by immigration or random mating. when two populations of same species share genes, variation occurs.

Natural selection: The favourable traits for survival are transferred to the offspring. It allows them to adapt better to the environment.  It allows maintenance diversity of organism.

Non random mating: The mating between the individual with varied genotype will result in genetic variation.

topjm [15]

The fraction of offspring that the Punnett square predict will be tall is ¾ (option C).

<h3>What is the punnet square?</h3>

The punnet square is a graphical representation used to determine the probability of an offspring expressing a particular genotype.

The punnet square is used to predict the percentage or proportion of offsprings of a cross that possess a specific genotype.

According to this question, a punnet square shows a cross between two tall pea plants. The allele for tall height (T) is said to be dominant while the allele for short height (t) is recessive.

If two heterozygous genotype crosses i.e. Tt × Tt, the percentage of offsprings that will be tall is 75% or ¾.

Therefore, the fraction of offspring that the Punnett square predict will be tall is ¾.
