What else can I help you with?
Where in the process of meiosis does nondisjunction occur?
Nondisjunction can occur during the separation of chromosomes in meiosis, specifically during the anaphase stage. This can lead to an abnormal number of chromosomes in the resulting gametes.
Does crossing over occur during prophase 2 of meiosis?
No, crossing over occurs during prophase 1 of meiosis, not prophase 2.
Is meiosis necessary before fertilization Can occur?
Yes, meiosis is necessary before fertilization can occur because meiosis is the process by which gametes (eggs and sperm) are formed. During meiosis, the cell's chromosome number is halved, so that when the egg and sperm fuse during fertilization, the resulting zygote will have the correct number of chromosomes.
In which stage of cell division, mitosis or meiosis, does crossing over occur?
Crossing over occurs during the prophase I stage of meiosis.
In mitosis and meiosis, does crossing over occur during the process of genetic recombination?
Yes, crossing over occurs during the process of genetic recombination in meiosis, but not in mitosis.
If a child is born with down syndrome when did the mutation occur?
During meiosis
When does replication occur during meiosis?
Interphase
Where in the process of meiosis does nondisjunction occur?
Nondisjunction can occur during the separation of chromosomes in meiosis, specifically during the anaphase stage. This can lead to an abnormal number of chromosomes in the resulting gametes.
When do homologus chromosomes occur short answer please thankss?
Homologous chromosomes occur during meiosis. Meiosis reduces the chromosome number by half.
What events occur in telophase?
Telophase occur in both mitosis and meiosis. During telophase nuclear membrane and nuclei reforms and in meiosis it further goes for meiosis 2 which is same as mitosis
During meiosis how many replications occur?
DNA replicates once during meiosis. This is why the end result is four haploid cells.
If child is born with trisomy when did the mutation occur?
during meiosis
What major events occur in telophase?
Telophase occur in both mitosis and meiosis. During telophase nuclear membrane and nuclei reforms and in meiosis it further goes for meiosis 2 which is same as mitosis
Does crossing over occur during prophase 2 of meiosis?
No, crossing over occurs during prophase 1 of meiosis, not prophase 2.
When a child is born with a chromosomal mutation when did mutation occur?
during meiosis
When a child is born chromosomal mutation when did the mutation occur?
During meiosis
