L10: Genetics
Introduction
What is genetic research?
Newer field of research
Study of heredity (how traits are passed on in generations)
Bio psych (10-14) 3
, Heredity also includes studying the biochemical mechanisms which
underpin it
☁️ Language clarity:
Of note; within genetics, biological organisms are frequently referred
to with regards to their genotype (their underlying biological makeup)
and phenotype (their observable traits).
Mendel
Gregor Mendel (1822-1884)
Credited as the first geneticist
Austrian monk and botanist
Bred/ crossbred peas
Findings
Noted dominant and recessive traits
Dominant traits expressed in an organisms phenotype
Recessive traits exoressed in absence of overshadowing dominant trait
Mendelian inheritance
Most phenotype traits depend on genes from parents
Receive an allele of each gene from each (aka. a ‘version’ of a trait)
Mendelian inheritance relies on two fundamental laws
Segregation - traits either dominant or recessive
