Which type of reproduction results in offspring that is IDENTICAL to the parent?
Asexual Reproduction
Sexual reproduction
When a new organism grows on the body of its parent. The bud, or offspring is identical to the parent. The bud can break off of the parent and live on its own.
Regeneration
Vegetative propagation
Fission
Budding
Why is an offspring from Asexual rep. identical to the parent but an offspring from Sexual rep. is not?
Because in Sexual there are 2 different sets of DNA from each parent. In Asexual there is only 1 parent.
Because in Asexual they choose to be identical
Because sexual reproduction has mutations
