Dear Past Jenni,

To help you learn about reproduction follow these pointers.

-- Punnett Squares; All the lower case letters are recessive and the capital letters are dominant. IF the combination is Yy, then it is a dominant trait.

-- Dihybrid Crossing; Dihybrid crossing is just a double punnett square. You have to do a combination of top row letters then side row letters.

-- Selective Breeding; Selective breeding is when you want certain traits from the parents to appear in the off-spring.

-- Incomplete; This is when two traits mix together to create a new species. A helpful example is flower colors.

Red + White= Pink

-- Co-Dominance; An example of co-dominance is camouflage or stripes. This is when there are two dominant traits present.

Two help you understand the last two terms, make a punnett square and try mentally breeding them. What happens if you breed dominant blue eyes with dominant Green eyes?

CO-DOMINANT

Hope these tips helped you out,

Jenni From the Future
