Answer:

allows the recombination of genetic information

Explanation:

Crossing over is a process that occurs only in meiotic division in sexually reproducing organisms. It is the process whereby the segments of a gene are exchanged between the non-sister chromatids of homologous chromosomes.

Due to this crossing over process that occurs in prophase I of meiosis, the alleles of a chromosomes are recombined to ensure genetic diversity. Hence, according to this question, crossing over results in additional genetic variation during meiosis because it allows the recombination of genetic information.

Identify whether the following statements are true or false.
Advocard [28]

The True statements are.

Organisms in a population must compete for the resources as the resources are limited and the organism that compete and survives wins.

The best equipped organism survive which is known as the survival of the fittest.

Over the time due to challenges in the environment the beneficial variation takes place in the organisms and it spreads through the generations and then it gradually changes the whole population.

The false statement is Organism of the same species are equipped with the same survival skills.

The organism of the same species have some variation and because of this variation they compete and win against the other member of the same species.

Low pitched male voices (RR) and a high pitched male voice (rr). Heterozygotes have a baritone voice. This is an example of ____
Lemur [1.5K]

Answer: incomplete dominance

Explanation:

Incomplete dominance is also referred to as partial dominance or semi dominance. It occurs when the two forms of gene in a trait combine in such a way that one does not have a dominance over the other one. Therefore, there's a blend of both genes in the physical appearance of such organism.

Therefore, a low pitched male voices (RR) and a high pitched male voice (rr). Heterozygotes have a baritone voice is an example of incomplete dominance.

After allowing his F1 crosses to self-pollinate, Mendel observed that
frutty [35]

Answer:

Explanation:

First-generation (F1) progeny only showed the dominant traits, but recessive traits reappeared in the self-pollinated second-generation (F2) plants in a 3:1 ratio of dominant to recessive traits. Mendel then crossed these pure-breeding lines of plants and recorded the traits of the hybrid progeny
