PQ 3

Heredity parents pass genetic information to their offspring
Chromosome contains thousands of genes (big)
Gene carries ONE single unit of information (medium)
DNA molecule that makes up genes (small)
Asexual ONE parent, offspring have same EXACT genes as its ONE parent
Sexual TWO parents; offspring has half genes from one parent, half from the other parent, and is not identical to either parent. (mix of the two)
Genetics Study of how genes are passed from one generation to the next
Punnet Square 4 squares that show the probability of a trait (eye color, hair color, height) being passed down to an offspring.
Dominant trait overpowers/hides another trait; a single copy of the gene (from one parent) is needed and the trait will show up in the offspringq
Recessive trait can be hidden by a dominant trait, you need 2 copies of the gene for the trait to be expressed
CAPITAL LETTERS Dominant trait ie: B = brown eyes
lowercase letters recessive trait ie: b = blue eye
