Yes, some gametes can be identical to each other after crossing over occurs during meiosis. Crossing over involves the exchange of genetic material between homologous chromosomes, which can create new combinations of alleles. However, if crossing over does not occur between two homologous chromosomes or if the alleles on the chromosomes are identical, the resulting gametes can be genetically identical.
What else can I help you with?
When somatic cells reproduce by mitosis does crossing over take place?
Yes. However, crossing over occurs much less frequently in somatic cells than in meiotic cells. Evidence of mitotic crossing over is the occurence of twin spots in Drosophila and other organisms.
Which phrase of meiosis occurs right after crossing over takes place?
After crossing over takes place during prophase I of meiosis, the next phase is metaphase I. During metaphase I, homologous chromosomes align at the metaphase plate, preparing for segregation. This alignment is crucial for the reduction of chromosome number and the promotion of genetic diversity in the resulting gametes.
What is meant by '' crossing over'' in terms of cells in your body?
it basically a chromosome that exchange parts and this leads to genetic variation. For example say 2 people where wearing bracelets and one wants what the other one has the, its just an exchange.
Phrase used to describe chromatids after crossing over takes place and the homologous chromosomes separate?
After crossing over occurs and homologous chromosomes separate, the resulting chromatids are referred to as "recombinant chromatids." This process involves the exchange of genetic material between non-sister chromatids, leading to increased genetic diversity in the resulting gametes. The recombinant chromatids carry a mix of alleles from both parents, contributing to variation in offspring.
Are gametes produced in the testes?
Yes, gametes are produced in the testes. In males, the testes generate sperm, which are the male gametes, through a process called spermatogenesis. This process takes place in the seminiferous tubules within the testes and involves the maturation of germ cells into functional sperm cells.
How many genetically distinct gametes are produced if crossing over does not take place during meiosis?
If crossing over does not occur during meiosis, two genetically distinct gametes are produced.
When somatic cells reproduce by mitosis does crossing over take place?
Yes. However, crossing over occurs much less frequently in somatic cells than in meiotic cells. Evidence of mitotic crossing over is the occurence of twin spots in Drosophila and other organisms.
What is meant to be segregation when sex cells are produces?
Freedom of genetic characters to move independently from parents to the gametes by the process of crossing over which takes place during meiosis.
Which phrase of meiosis occurs right after crossing over takes place?
After crossing over takes place during prophase I of meiosis, the next phase is metaphase I. During metaphase I, homologous chromosomes align at the metaphase plate, preparing for segregation. This alignment is crucial for the reduction of chromosome number and the promotion of genetic diversity in the resulting gametes.
When chromosome pairs separate into different sex cells does the alleles genes stay together?
During meiosis exchange of chromatid takes place by crossing over among the homologous chromosomes and chromatids of two chromosomes facing each other are involved in crossing over. Thus 50% of the gametes formed have new arrangement of alleles and rest 50% remain like those of parent cells.
Why did they build the Sydney harbor Brudge in the first place?
They needed a crossing from one side of the harbour to the other.
Where does the production of motile gametes takes place?
male gonads
Why does meiosis take place where does it take place?
It takes place in the sex organs. So it can produce 4 gametes.
Why do you use non-sister chromatids to demonstrate crossing over?
Crossing over occurs between homologous chromosomes, which are not identical, as one member of each pair of homologous chromosomes comes from the mother, and one member comes from the father. Sister chromatids are identical and crossing over would have no effect.
How do you get people to bid on your items in the auction for Animal Crossing City Folk for Wii?
Other residents place bids on it!
What is meant by '' crossing over'' in terms of cells in your body?

Where in the humans would you expect to find meiosis take place?
Gametes
