Introduction
Inheritance
Passage of hereditary traits from 1 gen to the next
Have a each pair, One chromosomes from father,
One chromosomes from mother
Homologous chromosomes
Paired chromosomes contain genes for same traits
Alleles gen - curly/straight hair
Mutation- permanent change in allele that produce different variant
Genetic
Branch of biology that deals with inherirtance
Type Inheritance
Genotype
Gene combination
Dominant gen
Recessive gen
Expression
Phenotype
Gene expression
Physical appearance
Complex Inheritance
Polygenic inheritance
Control by more than one gene
Other inheritance
combined effect from many genes
example : skin colour, hair colour, and height
Depends on environment condition
ex ; sun , nutrition
Sex Determination
Males
produced sperm X or Y
Baby's gender determine by father
