“Genes have specific loci along chromosomes & undergo segregation and independent assortment” Chromosomal inheritance generates genetic variation in sexual reproduction. Evidence: parallels between genes during meiosis and behavior of chromosomes Autosomal...

Chromosomal Inheritance and Environment Effects on Phenotype
Multifactorial characters: many factors, such as genes and environment affect phenotype Pedigree Analysis: Square is male, circle is female, painted in means they have that trait X-linked dom → father passes to all daughters; X-linked recessive → mother passes to all...
Rules of Probability
Rules of probability can be applied to analyze passage of single-gene traits from the parent to the offspring. For harder problems, where there are 2 alleles (AaBb) Mutually exclusive (can’t happen at...
Mendel’s Crosses
P generation: Parental generation, Mendel crossed a purebred purple with a purebred white plant People used to believe in blending inheritance: traits are mixed Ex: a tall person mates with short person = medium height baby F1 generation: created only purple plants,...
