Chromosome 5

Answer 1

The three most common autosomal trisomies in humans are trisomy 21 (Down syndrome), trisomy 18 (Edwards syndrome), and trisomy 13 (Patau syndrome).

Step-by-step explanation:

The three most common autosomal trisomies in humans involve chromosomes 21, 18, and 13. Trisomy 21, also known as Down syndrome, is due to an extra copy of chromosome 21 and is the most common trisomy among viable births. It can lead to certain physical and intellectual impairments. Trisomy 18, known as Edwards syndrome, and trisomy 13, known as Patau syndrome, can also result in live births, but affected individuals often have severe medical and developmental issues and a reduced lifespan.
