Gregor Mendel
|
Father of Genetics
|
|
|
Genetics
|
study of hereditary information that is passed on to the offspring
|
|
|
Parent (P) Generation
|
the 1st Cross
|
|
|
First filial (F1) Generation
|
offspring from the P generation
|
|
|
Second filial (F2) Generation
|
offspring from F1 generation
|
|
|
Dominant
|
trait your are going to see
|
|
|
Recessive
|
trait you don't see
|
|
|
Law of Segregation
|
Genes accure in pairs-they separate from each other during gamete formation (meiosis) and recobine at fertilization (zygote formation)
|
|
|
Gene-Chromosome Theory
|
genes are located on the chrosomes
|
|
|
Law of Independent Assortment
|
during meiosis genes for different traits separate and distribute to gametes independently of one another
|
|
|
Gene
|
trait or factor that you see
|
|
|
alleles
|
marks that represent the traits
|
|
|
Homozygous
|
TT (dominant) or tt (recessive) two of the same traits
|
|
|
Heterozygous
|
Tt-different traits
|
|
|
Hybrid
|
the offspring of crosses between pure parents showing contrasting traits
|
|
|
genotype
|
genetic makeup
|
|
|
phenotype
|
physical characterics
|
|
|
test cross
|
whether its TT (homozygous) or (heterozygous)
|
|
|
monohybrid cross
|
only one test of alleles
|
|
|
dihybrid cross
|
a genetic cross in which two pairs of contrasting traits are studied
|
|
|
incomplete dominance
|
a type of inheritance in which two contrasting alleles contribute to the individual a trait not exactly like either parent; blending inheritance
|
|
|
Codominance
|
a type of inheritance in which two dominant alleles are expressed a the same time without blending of traits
|
|
|
multiple alleles
|
three or more different forms of a gene, each producing a different phenotype
|
|
|
law of dominance
|
when an organism is heterozygous (hybrid) for a pair of contrasting traits (alles) only the dominant trait will be seen
|
