Genetics: study of how traits get passed from one generation to another
Mendelian Genetics
Gregor Mendal made the rules of genes
Mathematically figured out
figured out how genes were past on
Mendal studied common pea plants to derive the principles of heredity
pea plants were useful for the studying of heredity because
they are self pollinating
they grow fast
easy to develop pure-bred populations
Vocabulary
Genetic Traits
Any characteristic passed on by the parents to the offspring
Gene
a unit of genetic information for a particular trait that occupies specific position
Allele
Alternate version of a gene
Genotype
the genetic composition of an organism
Phenotype
how the genetic composition of an organism is physically expressed
Homozygous
when the two copies of a particular gene are the same allele (pure-bred)
Heterozygous
when two copies of a particular gene are different alleles
Dominant allele
when a particular allele , dominates other allele of that gene
Recessive allele
when particular allele can only be expressed
Test ran
Dominate trait will always be capitalized and the lowercase is recessive
