What is the importance of crossing-over?

Biology
1 answer:
nikklg [1K]3 years ago
3 0

Answer:

b.It increases the likelihood that daughter cells contain different genetic material.

Explanation:

Morgan and Cattell for the first time used the term ‘crossing over’.  Crossing over takes place during prophase I of meiosis. During crossing over, chromosome segments of non-sister chromatids of homologous chromosomes get exchanged. As a result, the daughter cells acquire different genetic materials. Thus, it provides genetic variation by creating a new combination of genes or get recombination and produces hybrids.

Answer:

OH LOL I DID THIS IN 7TH GRADE

Explanation:

so if i remember when the trees where white the pepper moths that where white survived more often that the black ones, then when the industrial war came the trees where covered in ash, so the white moths survived

MY SENTENCE

It shows how a change in an environment can effect a species natural selection, for example the white moths survived more than the black moths so the reproduced while the black moths where eaten by predator's, then when the environment changed and favored the black moths they survived and reproduced while the white moth got picked off by predators.

Hope this helped mate :>

Phenotype determines genotype. If false, make it a correct statement.<br> A. True<br> B. False
Gnoma [55]

Answer:

The correct answer is <em>B. False</em>

Explanation:

<em>The genotype of an organism determines its phenotype</em>. Phenotype is constituted by observable characteristics of an organism. These characteristics are codified by genes, and the combination of the differents variants of a gene which codify a phenotipic characteristic constitutes the genotype. For example: eyes color is a characteristic. Its is codified by variants of a gene. The combination of two variants of a gene gives a genotype, which codifies for the phenotype 'blue eyes'.

This interprets an RNA message into a string of amino acids called a polypeptide. Either single polypeptide or many polypeptides
vovangra [49]

Answer:

The correct answer is - translation

Explanation:

The translation is the second process involved in the protein synthesis in which mRNA that was encoded the genetic information from the DNA code during the transcription process, produces the amino acid sequence with the help of ribosome and tRNA.

These RNA messages or codes are decoded by the ribosome that produces a specific sequence of codes that form specific amino acid decided by the triplet code they produces. These amino acids together form polypeptides chain and single polypeptide or many polypeptides working together make up a protein.
