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.
If According to Mendel's law of segregation what happens to chromosomes during meiosis?
According to Mendel's law of segregation, during meiosis, homologous chromosomes separate so that each gamete receives only one allele for each gene. This process occurs during the first meiotic division (meiosis I), where homologous chromosome pairs are pulled apart into different daughter cells. As a result, each gamete produced contains a single set of chromosomes, ensuring genetic variation in the offspring when fertilization occurs.
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 is the similarities and difference between the segregation of genes and of chromosomes?
Both gene segregation and chromosome segregation involve the separation of genetic material during cell division. In gene segregation, alleles of a gene separate during meiosis, whereas chromosome segregation involves the separation of entire chromosomes. The key difference is that gene segregation refers to specific alleles segregating to daughter cells, while chromosome segregation refers to the distribution of entire chromosomes to daughter cells.

Steps in meiosis that increase variability?
crossing over of chromosomes, indepependent segregation of chromosomes and mutations
What happens to chromosomes for meiosis to start?
The chromosomes divide.
What is random distribution of homologous chromosomes during meiosis called?

What happens in meiosis one that does not occur in meiosis?
the synapsis and crossing over of homologous chromosomes
What are two functions of chiasmata?
Chiasmata are important for holding homologous chromosomes together during meiosis, facilitating genetic recombination between the chromosomes. They also help ensure proper segregation of chromosomes during meiosis by maintaining tension between homologous chromosomes.
Segregation of alleles occurs during?
Segregation of alleles occurs during meiosis, specifically during the separation of homologous chromosomes in anaphase I. This process ensures that each gamete receives only one copy of each gene, leading to genetic diversity in offspring.
True or false reassortment of chromosomes can occur during meiosis by crossing over or by independent segregation of homologous chromosomes?
True. Reassortment of chromosomes can occur during meiosis through both crossing over (where chromatids exchange genetic material) and the independent segregation of homologous chromosomes (where chromosomes separate randomly into daughter cells).
