Random chromosome assortment vs random chromatid assortment
Answers
Answer:
Explanation:
Random assortment of chromosomes refers to the way chromosomes get organized into daughter cells during gamete (sperm and egg) formation. It means that each sperm and each egg will have different combinations of chromosomes, some of which will have come from the person's mother and others from the father.
There are three mechanisms responsible for this: random assortment of chromosomes (chromosomes are sorted into daughter cells randomly), crossing over (chromosomes switch chunks of DNA) and random fertilization (chance alone is responsible for which sperm meets which egg).
Answer:
Crossing-over is the exchange of genetic material between non-sister chromatids of homologous chromosomes. ... When cells divide during meiosis, homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other. This is called independent assortment.
