What would happen if homologous chromosomes did not pair in prophase 1?

if homologous chromosomes didn't pair up in Prophase 1 the DNA between the parents isn't distributed equally to the offspring, or variation would not occur.

What cell has homologous chromosomes?
A somatic cell (body cell) is a cell that would have homologous chromosomes.
How would you know if 2 chromosomes were homologous pairs?
Therefore when two chromosomes of the exact structure exist, they are able to pair together to form homologous chromosomes
What stage in mitosis does the chromosomes uncoil happen?
During the telophase phase, the chromosomes begin to uncoil. There are six phases with mitosis and telophase is number four.
How are genes aligned on homologous chromosomes?
The genes are aligned between the pole, since it's involving homologous chromosomes, where all characteristics of chromosomes are the same, it kind of makes sense that identical genes would be aligned between the poles.
How would the karyotype of an organism that reproduces asexualy differ from a human karyotype?
Characteristics. Also, another difference between karyotype and karyogram is that while karyotype describes the number and appearance of chromosomes and includes their length, banding pattern, and centromere position, karyogram contains chromosomes arranged in an appropriate order.Jul
What would happen if homologous chromosomes paired with non-homologous chromosomes in meiosis 1 instead of the matching homolog?
good question!
What is the exchange of a corresponding segment between homologous chromosomes?
It would appear you are speaking of crossing over which takes place in Prophase I of meiosis.
Why do homologous chromosomes cross over?
Homologous chromosomes cross over to start genetic differences. If this didn't happen, then the cells would be too similar to each other. (｡-_-｡) that is all
What cell has homologous chromosomes?
A somatic cell (body cell) is a cell that would have homologous chromosomes.
When do the homologous chromosomes form tetrads?
Bivalents or Tetrad of homologous chromosomes consisting of four synapsed chromatids that become visible during the Pachytene stage of meiotic prophase or A four-part structure that forms during the prophase of meiosis and consists of two homologous chromosomes, each composed of two sister chromatids.
What phase would you first see chromosomes?
prophase
How would you know if 2 chromosomes were homologous pairs?
Therefore when two chromosomes of the exact structure exist, they are able to pair together to form homologous chromosomes
What stage in mitosis does the chromosomes uncoil happen?
During the telophase phase, the chromosomes begin to uncoil. There are six phases with mitosis and telophase is number four.
How many chromatids are visible at prophase?
It depends on the organisms. In humans there are 46 double chromosome, which are called sister chromatids. There are a total of 92 sister chromatids, which will eventually separate into individual chromosomes during anaphase of mitosis.
Describe three events that occur during meiosis 1 but not during mitosis?
1.Synapsis and crossing over in prophase I: Homologous chromosomes physically connect and exchange genetic information 2.At the metaphase plate, there are paired homologous chromosomes (tetrads), instead of individual replicated chromosomes 3.At anaphase I, it is homologous chromosomes, instead of sister chromatids, that separate
During which phase of meiosis do spindle fibers move the sister chromitatdes to the center of cells?
That would be anaphase I of meiosis. We know the question is concerning meiosis and not mitosis because it involves homologous chromosomes. Anaphase I begins when the kinetochore fibers stemming from the centrioles "grab" the centromeres of homologous chromosomes and "pull" them towards opposite ends of the cell.The mechanisms are a little more complicated than "grabbing" and "pulling," but for this question the mechanisms are of little importance.
How are genes aligned on homologous chromosomes?
The genes are aligned between the pole, since it's involving homologous chromosomes, where all characteristics of chromosomes are the same, it kind of makes sense that identical genes would be aligned between the poles.
