Question

We know that organisms pass traits onto their offspring through reproduction. So how is it

possible that a new trait could ever appear in a population? Wouldn't a trait have to already
exist in the population?

Answer 1

because of genetic variation.

Step-by-step explanation:

because of meiosis and a process called crossing over, there is genetic variation and diversity in the world, with humans and animals.

Answer 2

There are recessive traits and dominant traits

Step-by-step explanation:

recessive traits are always hidden

dominant traits are the ones that are present in an organism

some recessive traits can be passed on to offsprings to become dominant

and some dominant traits can be passed on to become recessive traits

that's life
