5 Human Chromosomes and Chromosome Behavior. 2 Human Chromosomes Humans contain 46 chromosomes, including 22 pairs of homologous autosomes and two sex.
What is a Karyotype? Karyotype: picture of an individuals chromosomes arranged in homologous pairs. Chromosomes are usually extracted during METAPHASE.

Karyotypes. Karyotypes are pictures of homologous chromosomes lined up together during metaphase I of meiosis. There are 44 autosomes and 2 sex chromosomes.
Sex Linked Traits Sex chromsomes: 1 pair female = XXmale = XY X chromosome: Y chromosome: larger, more genesmale traits female traitsdistribution of body.
Human Sex Chromosomes & linked Genes Human chromosome condition: diploid(2n) = 46. 44 (22 pair) = autosomes 2 (1 pair) = sex chromosomes (Y chromosome.
