- phenotype
- physical characteristics
- punnet square
- a chart that show all the possible conbinations of alleles that can result from a genetic cross
- codominance
- neither alleles are dominant or recessive
- individual alleles control the inheritance of _________.
- traits
- heterozygous
-
different pair
(hybrid)
ex. Tt - purebred
- only breed the same type together
- homozygous
-
same pair
(purebred)
ex. TT
tt - alleles

- geneticists use punnett squares to show all the ______ ______ of genetic cross and to determine the ____________ of a particular outcome.
-
possible outcomes.....
probability - alleles can be _____ or _____
- dominant or recessive
- genotype
- pairs of alleles ( TT, tt, Tt)
- mendal was the first scientist to recognize that the principle of probability can be used to _______ the _______ of _________ __________.
- predict the results of genetic crosses
- trait
- different physical characteristics
- genetics
- scientific study of heredity
- dominant alleles
- whenever present, always has that characteristic
- heredity
-
the passing of traits from parents to offspring
- hybrid
- two different alleles for the trait
- recessive alleles
- trait only shows up when a dominant isn't there
- probability
- the likelyhood that a particular event will happen
-
Mendal is often called the
