Mistakes such as nondisjunction can occur during meiosis. This is the result of chromosomes failing to separate equally during either anaphase. Therefore each resulting cell will not get an equal number of chromosomes. This can result in diseases such as Down syndrome (Trisomy 21, where there are 3 copies of the 21st chromosome present instead of the normal 2), or gender complications such as Klinefelter's (XXY) or Turner's (XO) syndromes.
What else can I help you with?
If a child is born with down syndrome when did the mutation occur?
During meiosis
When does replication occur during meiosis?
Interphase
Is it common for mistakes to occur during DNA replication?
Yes, it is common for mistakes to occur during DNA replication. These mistakes are known as mutations and can lead to genetic variations.
Occurs during prophase 1 of meiosis?
Crossing over between homologous chromosomes occurs during prophase 1 of meiosis. This process involves the exchange of genetic material between homologous chromosomes, leading to genetic diversity among the offspring.
Which does not occur during meiosis?
DNA replication does not occur during meiosis. Meiosis is a specialized cell division process that involves two rounds of division to produce gametes with half the number of chromosomes as the parent cell. DNA replication happens during the interphase preceding meiosis.
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.
During meiosis how many replications occur?
DNA replicates once during meiosis. This is why the end result is four haploid cells.
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
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.
