20+ Y Chromosome Definition Biology
Gif. Chromosomes are structures that bear dna but what is a homologous chromosome & interactions inside the cell during mitosis, meiosis what is a homologous chromosome? The y chromosome is one of the 46 (23 pairs) of chromosomes in humans, and also exists in many other mammals.
These cells contain half the number of chromosomes as body cells and are called haploid.
But now a team has discovered that x—the female chromosome—could also play a significant role in maleness. Each chromosome is made of protein and a single structure of chromosome. A chromosome is one of the threadlike packages of genes and other dna in the nucleus of a cell. The y chromosome is much smaller than the x chromosome and contains 50 million base pairs encoding.
