What else can I help you with?
Is duplication of paired chromosomes in the first stage of meiosis?
Yes duplication of chromosomes occurs during the first stage of meiosis or during prophase.
When a child has Trisomy when does the mutation occur?
during meiosis
Which process occurs when chromosomes do no separate during meiosis?
nondijunction
How many times do chromosomes make copies of themselves during meiosis?
Chromosomes make copies of themselves once during meiosis. This occurs during the S phase of interphase, which happens before meiosis I.
When does replication happen during mitosis or meiosis?
Replication occurs during the S phase of the cell cycle before both mitosis and meiosis. In mitosis, the replicated DNA is separated into two identical daughter cells. In meiosis, the replicated DNA is separated into four haploid daughter cells with genetic variation.
What is it called when a change in the chromosome during meiosis occurs?
This change is know as polyploidy.
Is crossing over a process that occurs during mitosis or meiosis?
Crossing over is a process that occurs during meiosis.
When does crossing occurs in meiosis?
Crossing over occurs during Prophase I.
Physical process that occurs more than once during meiosis?
During the process known as meiosis, cytokinesis occurs twice. Meiosis is cell division and is associated with sexual reproduction.
Is crossing over a key process that occurs during both mitosis and meiosis?
Yes, crossing over is a key process that occurs during both mitosis and meiosis.
Is duplication of paired chromosomes in the first stage of meiosis?
Yes duplication of chromosomes occurs during the first stage of meiosis or during prophase.
When a child has Trisomy when does the mutation occur?
during meiosis
Crossing over occurs during which phase of meiosis?
Crossing over occurs during Prophase I of meiosis.
Recombination occurs during?
meiosis
During which stage of meiosis are the bivalents arranged along the equator?
During the metaphase I meiosis are the bivalents are arranged along the equator. During the prophase I of meiosis I the crossing over occurs.
Which process occurs when chromosomes do no separate during meiosis?
nondijunction
Does crossing over occur in meiosis?
Yes, crossing over occurs during meiosis. It is the process where homologous chromosomes exchange genetic material, increasing genetic variation among offspring. This occurs during prophase I of meiosis.
