He would say that Lamarck's theory is wrong. Lamarck's theory stated that traits that are used are passed on to the offspring. In other words, if an organism changes during its lifetime in order to adapt to its environment, then its changes will be passed on to its offspring. This is wrong because this means that organisms pass on traits based on genetic information and not based on the environment of the offspring.
Hope this helps.
You should use a Punnett Square for this question
The Punnett square predicts the offspring of two parents (two alleles). In this case you have brown eyes (Bb) and blue eyes (bb)
In the four boxes you should have Bb, Bb, bb and bb (50% chance of offspring with blue eyes and 50% chance of offspring with brown eyes).
The genotypes ratio will be 2Bb:2bb
And the phenotypic ratio will be 2 Brown : 2 Blue
