Mendelian Genetics
Mendel's First Experiment
F1 generation
The hybrid offspring of the P generation
F2 generation
The hybrid offspring of the F1 genration
P generation
True-breeding parent plants (parental generation)
Monohybrid Cross
A hybridization where only one characteristic is examined
Law of segregation
heritable factors are segregated during gamete formation
Theory of Heredity
Dominant & Recessive alleles
Dominant= green pods that are passed on
Recessive= yellow pods that are silenced
Theory of Inheritance
When two different alleles are inherited together one may be expressed but not the other
Meiosis
each male or female gamete receives one allele for a trait
gametes
formations of different alleles
Punnett Squares
homozygous
particular gene that has identical alleles on both homologous chromosomes
heterozygous
genes that carry two different alleles
Genotype & Phenotype
phenotypes in the offspring of this cross from their genotypes
genotypes may vary by chance from the expected percentages
Non-Mendellian Inheritance
codominance = when phenotypes are associated with each alleleinherited are expressed to a certain extent
environmental effects
polygenetic traits
Mendel's Second Experiment
He was very curious on whether or not his science was accurate so he went deeper in
Dihybrid cross= two charachteristics at a time
he crossed plants with yellow round seeds and plants with green wrinkled seeds
Test cross
type of breeding that reveals the genotype of one parent based on the ratio of offspring observed
