How can prophase I and metaphase I in meiosis cause genetic variation in offerspring?
by being cheesy
Edited answer:
During prophase I of meiosis pairing among homologous chrosomes takes place. This is followed by crossing over. The recessive and dominant genes get interchanged during chiasma formation and such interchanged genetic material get separated in to different cells during mtaphase I. Hence, prophase I and metaphase I cause genetic variations in the male and female gametes. On randum mating among these gametes, genetic variation in the offsring are caused.
What else can I help you with?
What increases genetic variations?
A large population increases genetics variation. Mutation will also increase genetics variation.
Genetic variation is a necessary condition of which process?
Genetic variation is one of the conditions required for Natural Selection to occur.
Breeders can increase the genetic variation by inducing what?
The introduction of animals into a breeding population that are unrelated will increase genetic variation.
Which procedure can not be used to increase genetic variation?
If a population dwindles, there is low genetic variation and a species may risk extinction.
Which is responsible for genetic variation mitosis or meiosis?
Meiosis is responsible for genetic variation
Homologous chromosomes pair and undergo crossing over during?
prophase I of meiosis. This process involves the exchange of genetic material between non-sister chromatids, resulting in genetic variation among gametes.
What two factors introduce genetic variation during the process of meiosis?
The two factors that introduce genetic variation during the process of meiosis are independent assortment and chromosomal crossover. These occur during prophase 1 and anaphase 1 of meiosis.
What are the steps of meiosos?
Meiosis is a type of cell division that produces gametes, such as eggs and sperm. The steps of meiosis include meiosis I (prophase I, metaphase I, anaphase I, telophase I) and meiosis II (prophase II, metaphase II, anaphase II, telophase II). During meiosis I, homologous chromosomes pair up and exchange genetic material, leading to genetic variation. In meiosis II, sister chromatids separate to form haploid daughter cells.
What are the four parts of mitosis?
The four parts of mitosis are prophase, metaphase, anaphase, and telophase. In prophase, the genetic material condenses into chromosomes. During metaphase, the chromosomes line up along the metaphase plate. Anaphase involves the separation of sister chromatids, and in telophase, the nuclear membrane reforms and the chromosomes decondense.
What are the similar basic steps between mitosis and meiosis?
The similar basic steps between mitosis and meiosis include the stages of prophase, metaphase, anaphase, and telophase. Both processes involve the division of genetic material and the formation of new cells. However, meiosis includes an additional step called crossing over during prophase I, which results in genetic variation.
What process is responsible for genetic variation?
The process responsible for genetic variation is genetic recombination, which occurs during meiosis when genetic material is exchanged between homologous chromosomes. Mutations, which are changes in the DNA sequence, also contribute to genetic variation.
The process of cell division that creates genetic variety in cells is what?
The process of cell division that creates genetic variety in cells is called meiosis. Meiosis involves two rounds of cell division, resulting in the formation of four daughter cells with unique combinations of genetic material. This process is important for sexual reproduction and contributes to genetic diversity.
What are the different stages of meiosis and clever I be it's event?
Meiosis consists of two main stages: meiosis I and meiosis II. In meiosis I, homologous chromosomes pair up and exchange genetic material through crossing over in prophase I, leading to genetic variation. This is followed by the separation of homologous chromosomes during anaphase I. Meiosis II is similar to mitosis but involves the separation of sister chromatids, resulting in haploid daughter cells.
What process during meiosis leads to genetic variation?
DNA organizes into chromosomes within the nucleus
How does meiosis introduce genetic variation into offspring?
1 by crossing over in prophase I , 2 by independent assoartment and 3 by mutations in s phase .1 by crossing over in prophase I , 2 by independent assoartment and 3 by mutations in s phase .Meiosis produces variation in gametes by crossing over & independent assortment also called reshuffling of genetic material . Such gametes after fertilization produce offspring with different characters .
What increases genetic variations?
A large population increases genetics variation. Mutation will also increase genetics variation.
What order does the mitosis stage occur in?
ProphaseMetaphaseAnaphaseTelophaseSometimes, people will include a fifth event, called prometaphse, where the nuclear envelope disappears and the spindles form. Generally, this phase is classified with prophase.
