Human Mitochondrial DNA has a mere 16,569 base pairs or approximately 37 genes. It has a circular structure not a chromosome.
A fruit fly, specifically Drosophila melanogaster, has a total of 8 chromosomes, which are organized into 4 homologous pairs. This means that there are four pairs of chromosomes that are similar in shape, size, and genetic content, one inherited from each parent.

One person has 46 chromosomes or 23 pairs.
2n= 24 therefore one set consists of 12 chromosomes.
All 23 pairs of chromosomes are in the shape of an X, except for the Y chromosome, of which one is found in the nucleus of each male cell. This one is (surprise, surprise) in the shape of a Y. If you look at a human female cell, all 23 pairs are comprised entirely of X-shaped chromosomes.
Chromosomes that have the same size and shape are called homologous chromosomes. These chromosomes carry the same genes, although they may have different versions of those genes. Homologous chromosomes are typically found in pairs, one inherited from each parent.
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.
38 chromosomes in one cell.

The matching pairs of chromosomes in a diploid cell are called homologous chromosomes. These chromosomes are similar in size, shape, and genetic content, with one chromosome inherited from each parent. Homologous chromosomes undergo genetic recombination during meiosis.
