Genetics
Dihybrid crosses
Genes on separation chromosomes Independent assortment
One genes move independent of the alleles of the other
Cross-over
Rate is directly proportional physical spacing between genes
4 types not equal
First 2 Parental type chromosomes
Last 2 are recombinant chromosomes
Genes on the same chromosomes linkage
No independent assortment
Multiple Genes for one characteristic
Each with it's own Enzyme
Multiple genes for one trait Epistasis
Quantitative Trait loci
Multiple phenotype effects of one mutation
Pleiotropic effects
Other Aspects of Inheritance
Maternal Inheritance
Biparental inhertiance
sperm cell loses most of it's cytoplasm
Lethal Alleles
can be difficult to detect
Multiples Sets of Chromosomes and gene families
Achlorophyllous Plant
Pollen parent
Ovule parent
Plastid inheritance
Variegation in plants
More than 2 sets chromosomes call polyploid
Polyploid
Nondisjunction
paralogs. similar to wild type alleles
Multiple copies make up GENE FAMILY
Replication of DNA
Material Inheritance
Replicon
Primer RNA
DNA Polymerase
Forked appearance
Ligated
Sexual reproduction between two individuals called a cross
Zygote has two complete sets of genes
Single character is analyzed
Mendal
Homozyous/ Heterozyous
Monohybrid Crosses
Multiple Alleles
Altered protein structure
Test Crosses
Complete dominance
Pure blood lines
Monohybrid crosses with complete dominance
Dominate
Recessive
Crossing Heterozygotes with themselves
