Question

give an example for a allosomal trisomy

Answer 1

Trisomies are sometimes characterised as "autosomal trisomies" (trisomies of the non-sex chromosomes) and "sex-chromosome trisomies." ... Thus, for example, the presence of an extra chromosome 21, which is found in Down syndrome, is called trisomy 21.

Answer 2

Trisomy 21 (Down syndrome)

Trisomy 18 (Edwards syndrome)

Trisomy 13 (Patau syndrome)

Trisomy 9

Trisomy 8 (Warkany syndrome 2)

Of these, Trisomy 21 and Trisomy 18 are the most common. In rare cases, a fetus with Trisomy 13 can survive, giving rise to Patau syndrome
