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 are haploid cells so N chromosomes.
Are homologous chromosomes normally found in gametes? yes
yes because there are then two chromosomes in the cell that line up (for example chromosome 17 to chromosome 17)
Yes they are.
Its really critical thinking.
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.

Chromosomes that have the same sequence of genes are called homologous chromosomes.
They have homologous chromosomes
The exceptions to the rule that every chromosome is part of a homologous pair are the gametes. Gametes are eggs and sperm, and each cell has only 23 chromosomes, which form pairs in the zygote after fertilization.
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.
Complicated.
nondisjunction
Segregation
homologous
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.

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.
