Cell Cycle |
2 Stages Interphase-Phase b/t divisions,90% of the time G1-Gap 1/ prepare for s S-Dna Synthesis(replication) G2-Gap 2, prepare for M Mitotic Phase-includes mitosis and cytokinesis |
|
|
Chromosomes |
Prokaryotic-Single cell Ex:Bacteria
Eukaryotic-condensed DNA Long, Linear DNA Models 46 chromosomes/ 23 pairs |
|
|
Eukaryotic chromosome |
chromatids joined at centromere |
|
|
Cell Division |
reproductive signal replication of DNA segregation of DNA Cytokenesis
|
|
|
Mitosis |
identical cells produced 2 cells produced somatic cells 1 major divison
|
|
|
Meiosis |
not identical cells 4 cells gametes 2 major divisions |
|
|
Mitosis and Cytokenesis |
production of 2 daughter cells replicates the mother cell 4 gametes are produced cuts chromosomes in half in eukaryotes |
|
|
GENE |
unit of inheritance/part of DNA on chromosome that encodes a particular character locus-specific location on chromosome allele-different gene forms dominant vs. recessive |
|
|
phenotype vs genotype |
Phenotype:physical appearance
Genotype:Genetic Makeup |
|
|
Homozygous vs. Heterozygous |
Homo=2 identical alleles
Hetero=2 different alleles |
|
|
Law of independent assortment |
alleles of 2 or more pairs of different characters segregate independently of one another during gamete formation
|
|
|
Dihybrid cross |
both parents are double heterozygotes in F1 generation FOIL |
|
|
Incomplete dominance |
heterozygous phenotype is intermediate between 2 homozygous phenotypes. EX: Red+White=Pink |
|
|
Codominance |
2 alleles, 1 is dominant EX:AB blood |
|
|
Pleiotropy |
Single allele produced many phenotypic effects |
|
|
allele |
gene received from a parent |
