|
Diploid |
Two copies of every chromosome (2n)
|
Di = 2 |
|
|
Haploid |
One copy of each chromosome (n) |
There is only ONE a |
|
|
Meiosis |
cell division that only produces gametes (Haploid cells) |
There is no T! |
|
|
Meiosis 1 |
1st Stage of meiosis |
|
|
|
Prophase 1 |
Homologous chromosomes pair up |
|
|
|
Metaphase 1 |
The pairs line up, and pair randomly |
|
|
|
Anaphase 1 |
Homologous chromosomes are pulled to opposite poles of the cell |
|
|
|
Telophase 1 |
Chromosomes reach poles |
|
|
|
Cytokinesis 1 |
Cell divides |
|
|
|
Meiosis 2 |
Just like Mitosis |
2nd Part of the last part |
|
|
Prophase 2 |
fibers attach |
|
|
|
Metaphase |
line up in middle |
|
|
|
Anaphase 2 |
pull apart |
|
|
|
Telophase 2 |
Reach poles, nuclear envelope re-forms.
|
|
|
|
Cytokinesis 2 |
cells split. |
|
|
|
Genotype |
homozygous dominant/recessive heterozygous |
How many different letters are in gene, and how many different genotypes are there? |
|
|
Phenotype |
The actual physical trait the organism has (Dominant/Recessive) |
How many letters makes the "f" sound, and how many phenotypes are there? |
|
|
Punnet Square |
Tool to predict the phenotype of offspring |
So*v* **r Pr*di*****s |
|
|
Simple Recessive Heredity |
Most genetic disorders Most rare vary by ethnicity need 2 recessive alleles to have disease heterozygoes for trait = carrier |
Is recissive rare or common |
|
|
Simple Dominant Trait |
Allele causes trait |
What is more op, dominant, or recissive |
|
|
Complex Patterns of Inheritance |
Incomplete Dominance/Co-Domincance/Multiple Alleles/Polygenic Inheritance/ Sex-Linked |
There are multiple types of patterns |
|
|
Incomplete Dominance |
Heterozygous phenotype is a blend between the two alleles Red Carnation + White Carnation = Pink Carnation |
Mix two things |
|
|
Co-Dominance |
Heterozygous causes both to show up. Black Chicken + White Chicken = Black and White Chicken |
Both show, seperately |
|
|
Multiple alleles |
Some traits have more than two possible alleles. Rabbits: Black White Grey Dark Grey Albino |
Many alleles |
|
|
Polygenic Inheritance |
Some traits are controlles by many different genes - Each gene is expressed by "turning on or off" Melonine - more melonine darker skin is. |
Poly needs to "turn on" there money saving tips on there Iphones. |
|
|
Sex Determination |
Depends on gender, on if you are more or less likely to get a disease. X-Linked Traits Y-Linked Traits |
Genes. |
