But we also know that because no variations

occurred in the population that both parents

where homozygous for that trait. However ALL

the offspring are heterozygous.

Now here is where we can take a big short cut

in manipulating the gene pool for that

population.

By cloning the parent plant MM, we can use this

clone in our cross with the Mm offspring. This

is known as a BACKCROSS. Obviously if our

parent is female then we will have to use males

from the Mm selection in out backcross.

Now out first backcross will result in 50%

being homozygous for that trait (MM) and 50% of

the offspring being heterozygous (Mm) for that

trait!

If we did not backcross but just used the

heterozygous offspring for the breeding

programme we would have ended up with:

(^) M m
M MM Mm
M MM Mm
