Question

In Which Organism sex is not determined genetically?

• A. Butterfly
• B. Moth
• C. Sparrow
• D. Snail

Answer 1

Answer:

D. Snail

In snails, sex determination can be influenced by environmental factors rather than genetic inheritance. In snails, the sex of an individual is not strictly determined by genetics alone. Instead, environmental conditions can influence whether an individual becomes male or female as it grows. This phenomenon is known as sequential hermaphroditism, where an organism can change its sex during its lifetime.
