Propose how crossing-over during meiosis might affect the segregation of genes that are on the same chromosomes?

Segregation is the separating of genes into different cells during meiosis. We have found that there are many more genes that display segregation than there are chromosomes. The explaination is crossing-over - where during prophase I chromosome arms of homologous chromosomes break off and attach to each other. This allows genes on the same chromosome to segregate.

What is unique to mitosis and not a part of meiosis?
homologous chromosomes behave independently Pairing of homologous chromosomes allowing independent segregation and crossing over is unique to meiosis. In mitosis, homologous chromosomes behave independently.
Do homologous chromosomes separate only in meiosis?
yes. in mitosis there is separation of sister chromatids
What can we observe in order to visualize Mendel's Law of Segregation?
homologous chromosomes separating during meiosis I
True or false reassortment of chromosomes can occur during meiosis by crossing over or by independent segregation of homologous chromosomes?
Independent assortment occurs when each pair of chromosomes segregates independently?
Segregation of alleles occurs during?
Segregation.
How genatic material can be rearnged during meiosis?
By crossingover.
Steps in meiosis that increase variability?
crossing over of chromosomes, indepependent segregation of chromosomes and mutations
What is random distribution of homologous chromosomes during meiosis called?
Segregation distortion, non-mendelian segregation.
When alleles on homologous chromosomes move into different gametes during meiosis this demonstrates?
Segregation

What happens to chromosomes during meiosis According to Mendel law of segregation?
According to mendel's law of segregation, what happens to chromosomes during meiosis is that, allele pairs do separate leaving each and every cell with a single allele for each trait.
What happens to chromosomes during meiosis according to mendels law of segregation?
According to mendel's law of segregation, what happens to chromosomes during meiosis is that, allele pairs do separate leaving each and every cell with a single allele for each trait.
According to Mendel’s law of segregation, what happens to chromosomes during meiosis?
According to mendel's law of segregation, what happens to chromosomes during meiosis is that, allele pairs do separate leaving each and every cell with a single allele for each trait.
Why meiosis gives 4 different gametes?
Because of the crossingover and independant assortment happens in metaphase1.
Do homologous chromosomes separate only in meiosis?

What can we observe in order to visualize Mendel's Law of Segregation?
homologous chromosomes separating during meiosis I
How does mitosis differ from meiosis in terms of chromosome segregation?
Meiosis results in four cells, each with half the chromosomes of the original cell. Mitosis results in two cells, each which has the same number of chromosomes as the original cell.
