Question

Is dwarfism a chromosome disorder or a gene disorder?

Answer 1

Dwarfism, or achondroplasia, is a chromosomal disorder.

Answer 2

I thought it was a gene disorder

Answer 3

Sorry, you're right. It's a genetic disorder.

Answer 4

It's definitely genetic... I'm sure this time. :)

Answer 5

It's genetic because you can only get it if both of your parents are heterozygous: Example:
Both parents are Aa, therefore, the only possibility that their offspring will be of dwarf genotype is if the alleles turn out to be aa, which is homozygous recessive :)
