Homologous chromosomes (also called homologs or homologues) are chromosome pairs of approximately the same length, centromere position, staining pattern, with genes for the same characteristics at corresponding loci.
In meiosis I, the chromosomes are duplicated first then the homologous pairs separate together. Sections of the DNA can sometimes cross over between homologous pairs.
Later, during Meiosis II, these pairs are separated into the gametes with only one of each pair.
If you said there was only one chromosome, you are thinking of the final result of meiosis.
A chromosome is a structure within a cell that contains genetic information. Damage to a chromosome may lead to a mutation in the daughter cells.
Sexual reproduction took me a while 2 figure it out 2
A chromatid is one half of a chromosome at a stage of the cell cycle when the chromosome contains two molecules of DNA.A chromatid is like a twin; you can only use the term when there are two of them!Before DNA replicates, each chromosome has only one molecule of DNA. After replication of the DNA, there are two DNA molecules in each chromosome. These become visible under a light microscope when the chromosomes condense during prophase of the next division.Each chromosome then looks like an X. The left side of the X contains one DNA molecule (together with proteins) and the right side contains the other. Each half of the chromosome is a chromatid. At anaphase of the division, the two chromatids are pulled apart. From then on they are no longer referred to as chromatids, but as daughter-chromosomes.
Gametes are haploid.EDIT:Meiosis produces four haploid cells after Telophase II and cytokinesis.But he/she is right. Gametes are haploid cells.

The chromosome number for daughter cells resulting from mitosis is the same as the parent cell.

The process by which a daughter cell accidentally get two copies of a chromosome is called "nondisjuction".
Mitosis
That happens in Ana phase.When a chromosome is not split in centromere,a chromosome fully moves to a daughter cell.
the daughter cells are similar to the mother cell and they have the same chromosome no.

Sex-linked disorders are passed on the X chromosome. The man supplies the Y chromosome to his sons so the disorder cannot be passed on to the sons. But the man gives his daughter an X chromosome so the disorder can be passed on to her.
