Chromosomes normally occur as homologous pairs in a diploid cell. These refers to matching pairs of chromosomes which are found in the cell.
They are called homologous chromosomes (but can also be referred to as homologues or homologs).
A human gamete does not have any pairs of homologous chromosomes. A single human gamete contains 23 chromosomes, or a half set. None of these chromosomes are homologous with each other.
Human cells have 23 homologous pairs. They also must go through meiosis before that. Females have 2 X chromosomes, while Males have an X and a Y chromosome. That's why the males cells decide the gender of the child.
there are 23 pairs of matching chromosomes 46 chromosomes altogether.
During meiosis, the homologous chromosomes come together during prophase I. Pairs of homologous chromosomes align during a process called synapsis and form a tetrad (four sister chromatids, two from each pair of homologous chromosomes). During synapsis, crossing over may occur, during which homologous chromosomes exchange genetic material.
Homologous pairs of chromosomes are not normally found in a zygote.
It has pairs of matching chromosomes.
