Gametes are the male and female reproductive cells, sperm and eggs. These cells are produced by a cell that undergoes meiosis. That process creates 4 haploid cells, haploid meaning that there is only one set of chromosomes in each cell. A normal, or diploid, cell would have homologous pairs but because a gamete is haploid, it only has one half of the homologous chromosomes.
For instance a human has 46 chromosomes, so there are 23 pairs of chromosomes. Every diploid cell has all 46 but gametes only have 23 chromosomes in every cell.
Also when the cell is under going meiosis crossing over of the chromosomes during metaphase can occur, so the haploid cells that result from meiosis are not genetically identical.
Homologous genes which have the same genetic information on each of their chromosomes e.g XX. You can find 23 in a sperm and an egg and so when they fuse it forms 46 which is the number found in a human.
Gametes have 23 chromosomes each, consisting of one set of 23 chromosomes, with each chromosome being homologous to a corresponding chromosome in the other set.
yes because there are then two chromosomes in the cell that line up (for example chromosome 17 to chromosome 17)

Occurs when homologous chromosomes do not separate in meiosis?
Nondisjunction is the term used for when homologous chromosomes fail to separate during meiosis, resulting in an abnormal number of chromosomes in the resulting gametes. This can lead to genetic disorders in offspring due to an incorrect number of chromosomes.
How many homologous pairs of chromosomes does a diploid human cell have?
A diploid human cell has 23 pairs of homologous chromosomes, for a total of 46 chromosomes.
How is genetic variation among gamete produced during meiosis?
Genetic variation among gametes is produced during meiosis through processes such as crossing over (exchange of genetic material between homologous chromosomes), independent assortment (random orientation of homologous chromosomes), and random fertilization (combining of different gametes). These mechanisms shuffle and mix genetic material from the parents, leading to new combinations of alleles in the gametes and promoting genetic diversity.
How many pairs of homologous chromosomes do leopard frogs have?
Leopard frogs have 13 pairs of homologous chromosomes, for a total of 26 chromosomes.
The exceptions to the rule that every chromosome is part if a homologous pair are the?
The exceptions to the rule that every chromosome is part of a homologous pair are the sex chromosomes (X and Y chromosomes). In humans, females have two X chromosomes, while males have one X and one Y chromosome, which do not pair up fully during meiosis.
What does Gametes have?
Homologous chromosomes
Know whether or not gametes have homologous chromosomes?
Gametes are said to have homologous chromosomes, if they have same genes arranged in same order. During gamete formation meiosis precedes, therefore, individual gamete does not have its homologous counterpart. After fertilization, in diploid nucleus, homologous chromosomes are restored.
Where are homologous pairs of chromosomes not normally found in?
Homologous pairs of chromosomes are not normally found in gametes, which are reproductive cells such as eggs and sperm. This is because gametes are haploid, meaning they only contain one set of chromosomes, while homologous pairs consist of two sets of matching chromosomes.
What is it called when homologous chromosomes fail to separate properly causing to the gametes to have too many or too few chromosomes?
Complicated.
Failuare of homologous chromosomes to separate properly during meiosis result in gametes with too many or too few chromosomes?
nondisjunction
When alleles on homologous chromosomes move into different gametes during meiosis this demonstrates?
Segregation
Occurs when homologous chromosomes do not separate in meiosis?
Nondisjunction is the term used for when homologous chromosomes fail to separate during meiosis, resulting in an abnormal number of chromosomes in the resulting gametes. This can lead to genetic disorders in offspring due to an incorrect number of chromosomes.
The net result of meiosis is to reduce the number of chromosomes in gametes to only one from each?
homologous
Do you agree or disagree that homologous chromosomes are found in gametes?
Have to say Nay. Two chromosomes are 'homologous' , to my understanding, only if each is IDENTICAL with the other - this means a pair. Gametes are haploid, meaning that only one copy of each (normally diploid or paired) chromosome (s) is (are) present.

What human body cell consists of 22 homologous pairs?
Any human cell except for the gametes (sperm and egg cells) consists of 22 homologous pairs of autosomes. Gametes have one set of 22 autosomes but not homologous pairs, as they are haploid cells.
