offspring?
6 o'clock - With your partner...
1. Explain the concept of mutations in a real life situation.
> What types of mutations are there?
> What if the difference between a mutation that happens in
a body cell vs a mutation that happens in a gamete?
2. Which mutations (sentence change) is more severe and
why? What happens as a result of this mutation?

How can we predict the genetic variability of
offspring?
In cattle, the hornless condition (H) is
and the horned condition (h) is
> A bull without horns is crossed with a cow with horns. –
Of the four offspring, one (1) is horned and three
(3) are hornless. Determine the genotype of the
bull and the cow.
