Question

What did H. Henking originally call the nuclear structure he discovered during his 1891 study of squash bug spermatogenesis?

Options

• X body

• Sex body

• Y body

• Nuclear body

Answer 1

Henking named the nuclear structure he observed the 'X body,' though he could not initially explain its significance. Later scientists confirmed that this X body was a chromosome and renamed it the X chromosome, establishing the first cytological evidence for a sex-determining factor in organisms.
