A chromosome contains numerous
genes and consists of 2 sister chromatids joined at the centromere.
Each homologous pair is composed of one chromosome from the maternal
set and one from the paternal set.
A cell that has a full set of chromosomes from both parents is
A karyotype is a display of condensed
mitotic chromosomes arranged in homologous pairs.
Human somatic cells have 22 pairs of homologous autosomes (each of the
pair inherited from one of the 2 parents), plus one pair of sex
chromosomes (X or Y).
XX individuals are female, while XY are male.
This karyotype shows the chromosomes from a male.
