Answer: Crossing-over allows the genes that come from each parent to recombine before they are passed on to future generations because chromatids of homologous chromosomes mate and exchange sections of their DNA.
Explanation:
Chromosome crossing-over is the process by which chromatids of homologous chromosomes mate and exchange sections of their DNA during prophase I of meiosis, when pairs of homologous chromosomes, or of the same type, are aligned. The chromatids of the homologous chromosomes break off in the chiasmas and rejoin to allow recombination of the linked genes. So it occurs when regions at chromosome breaks mate and then reconnect to the other chromosome. <u>The result of this process is an exchange of genes, called genetic recombination</u>.
This allows the genes that come from each parent to recombine before they are passed on to future generations. Then, <u>it is an important source of genetic variability</u>, since it involves an exchange of segments between homologous chromosomes during the development of gametes. <u>This process allows that the descendants of an individual are genetically very different</u>, since it is very unlikely that an individual produces two equal gametes, because all of them have different segments of the homologous chromosomes.
Ingesting a meal will increase your sugar levels, so you need more insulin released to combat that. There will be more insulin released in your body and less glucogon.
Answer:
Las células hijas de mitosis se denominan células diploides. Las células diploides tienen dos conjuntos completos de cromosomas. Puesto que las células hijas tienen copias exactas del ADN de la célula madre, no hay diversidad genética creado a través de la mitosis en las células sanas normales.
Answer:
The phrase that best describes the Osorno volcano is <u>DORMANT VOLCANO.</u>
Explanation:
Osorno volcano can be described as a stratovolcano that is covered in glacier. The Osorno volcano originates in a symmetrical manner. It has been known to cause eleven eruptions in the ancient times. Osorno volcano is claimed to be among the most active volcanoes occurring in the country of Chile. Osorno is a city in Chile present in the southern central region of Chile on a river termed as Rahue River.
Answer:
Known as the cell's “command center,” the nucleus is a large organelle that stores the cell's DNA (deoxyribonucleic acid). The nucleus controls all of the cell's activities, such as growth and metabolism, using the DNA's genetic information.
