How many chromosomes do primates have?
Humans have 46 chromosomes, whereas chimpanzee, gorilla, and orangutan have 48. This major karyotypic difference was caused by the fusion of two ancestral chromosomes to form human chromosome 2 and subsequent inactivation of one of the two original centromeres (Yunis and Prakash 1982).
Does milk contain DNA?

What is the difference between normal and abnormal karyotype?

What does each chromosome determine?
An organism has the same chromosomes for its entire life. The chromosomes are located within each cell nucleus.
