Recessive gene
effect is masked out by the allele


Punnett square
use to work out genetics problems


Dominant gene
masks the effect of the contrasting gene


Mendel's conclusion
Double dose of factors(alleles).

P1
parental generation, the starting plants

Tall X Short
TT X tt


Diabetes
caused by a recessive allele


alleles
contrasting forms of the same gene


Heterozygous
one of each allele (e.g. Tt)


Homozygous
Two alleles that are the same (e.g. tt, TT)

F1
second generation, filial generation

Tall X Tall
Tt X Tt


carrier
when one has the recessive allele of a dominant trait.

F2
second Filial generation


3/4 tall
1/4 short
ratio of 3:1


Gregor Mendel
a monk
determined inheritence pattern
father of modern genetics
pea plants


Probability
The chance of something happening. P=m/n
P=probability, m=desirable outcome, n=total possible outcome
always between 0 and 1.


Genes
-on our chromosomes
-control traits


The smaller the sample size...


The bigger the variation


Genotype
the genes that create your appearance


Mendel's success due to:
-luck
-look at limited # of traits
-was good at statistics
-large sample size
-kept careful records
-used self-pollination, cross-pollination


Cross-pollination
Take plant A and removet he stamen leaving only the pistal. Take the stamen of plant B and put it to the pistal of A.


Phenotype
the appearance
