In sexual reproduction, an offspring is produced with genes from both parents. When the offspring has a new genetic variation that it got from neither of its parents, it is called
A.
an autosome.
B.
a phenotype.
C.
a recessive gene.
D.
a mutation.
This would be called a mutation because it stated above neither of it's parents have it so say for humans both parents have 2 arms which is normal. They have a child and he/she only has one arm thus mutation.
