|
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
|
