Chromosomes are paired in cells during a process called meiosis, which is a type of cell division that produces sex cells (sperm and egg). In meiosis, the cell first duplicates its chromosomes, creating two identical copies called sister chromatids. These sister chromatids then pair up with their corresponding chromosome from the other parent, forming a homologous pair. This pairing is important for genetic diversity, as it allows for the exchange of genetic material between the homologous chromosomes through a process called crossing over. This exchange of genetic material results in new combinations of genes, leading to genetic variation in the offspring.
The paired chromosomes that determine an individual's gender are called sex chromosomes.
The paired chromosomes that are similar within an organism, including autosomes, are called homologous chromosomes.
The total number of paired chromosomes in a body cell is called the diploid number. In humans, the diploid number is 46, with 23 pairs of chromosomes.
The chromosomes that are paired, one from each parent, are called homologous chromosomes. These chromosomes carry genes for the same traits and are similar in size and shape. During meiosis, homologous chromosomes exchange genetic material through crossing over.
Tetrads are formed of 2 homologous chromosomes, which are crossing over so there is a total of 4 chromatids. :D
Except for the sex chromosomes paired chromosomes are homologs.
