Science 4.2


Probability Is a number that describes how likely it is that an event will occur
Punnet Square is a chart that shows all the possible combinations of alles that can result from a genetic cross
Phenotype An organism's phenotype is its physical appearance, or visible traits.
Genotype the genetic makeup, or allele combinations
Homozygous An organism that shows two identical trait
Heterozygous An organism that shows two different traits
codominance The alleles are neither dominant or recessive
What is probability and how does it help explain the results of genetic crosses? Probability is the number that describes how likely the event will occur. It helps explain because if there wasn't probability, it would be harder to guess at things. Like if someone's dad was a homozygous recessive blue eyed. And the mother was heterozy-
gous brown eyes. How would they know what color eyes the child would have it woud be 50%.
What is it meant by genotype and phenotype? Genotype is the genetic makeup and phenotype is the physical appearance
What is codominace? It is when one genotype isn't dominant over the other like AB.
