Which Best Describes How Meiosis Contributes to Genetic Variation

The gene for tallness T in a pea plant is dominant over the gene for shortness t. Which of the following BEST describes a way that meiosis generates genetic variation.

Genetic Variation In Meiosis Biology For Majors I

Combining genetic material in new ways in offspring.

. Homologues within tetrads line up randomly along either side of the metaphase plate in meiosis II. Meiosis reduces the number of chromosomes so that gametes are haploid or cells that contain only one set of chromosomes. You start with a diploid 2n cell and end with 4 n haploids.

Because genes will be in a new order on some chromosomes additional DNA will need to be made D. The independent orientation of the chromosomes during prophase I of meiosis. What would most likely happen if the rabbit population decreased as a result of another predator being introduced to the food web.

Which best describes the role of enzymes in a chemical reaction. There are two divisions that occur during the entire process of meiosis ending in haploid cells. Which best describes how meiosis contribute to genetic variation.

When combined with another gamete during fertilization there are over 64 trillion possible outcomes for any one offspring. Meiosis also allows genetic variation through a process of gene shuffling while the cells are dividing. Meiosis results in novel combinations of alleles in offspring.

Chromosomes in a eukaryotic cell are composed of DNA. Increase the reaction rate. Crossing over or recombination between chromatids of homologous chromosomes during meiosis.

Random mating between organisms. Meiosis I and II contributes to genetic variation by. What best describes how meiosis contributes to genetic variation.

Crossing over or recombination between chromatids of homologous chromosomes during meiosis. Mitosis and meiosis the two types of cell division. The end result includes chromosomes with genes from.

There are two ways meiosis causes genetic diversity. Meiosis also creates genetic variation through the process called crossing over where chromosome segments are exchanged. During Prophase I of Meiosis I a unique event occurs called crossing over.

Meiosis I and II are both processes of cell differentiation where two cells divide to produce four daughter cells which contain genetic information. In some cases these new combinations may make an organism more or less fit able to survive and reproduce thus providing the raw material for natural selection. Heres a brief overview.

Which events contribute to. Crossing over occurs during meiosis and contributes to the genetic variation in a population of organisms by. The genetic variation part.

What are the three ways meiosis increases genetic variation. The genetic variation part. What best describes how meiosis contributes to genetic variation.

Which of the following BEST describes a way that meiosis generates genetic variation. By recombining the genetic material in two ways with a third way furthering variation. Both fertilization and meiosis contribute to genetic variation.

Recombination in prophase meiosis I reducing the number of chromosomes to half. Meiosis and fertilization create genetic variation by making new combinations of gene variants alleles. Random mating between organisms.

There are two phases Meiosis I and Meiosis II. Produces a new individual different from either parent. What are three ways meiosis leads to genetic variation.

Meiosis I starts with one diploid parent cell and after its division. The end result includes chromosomes with. Alleles from egg and sperm separate during meiosis I.

How does crossing-over during meiosis contribute to genetic variation. Meiosis is recognized as a process that contributes to genetic variation. Crossing-over always causes loss of some genetic information C.

Group of answer choices Chromosomes replicate during S phase but do not replicate again after meiosis I. During Prophase I of Meiosis I a unique event occurs called crossing over. Each cell created has chromosomes only from a single parent B.

Which of the following characteristics of meiosis explains why this process contributes to genetic diversity within a population. Crossing over between. A Sister chromatids separate evenly into during melosis II B Homologues within tetrads line up randomly either side of the metaphase plate in meiosis II c Alleles.

Giving each daughter cell one chromosome from the chromatids which remains after Meiosis I.
