The Chromosomal Theory of Inheritance

Chromosomes carry WHAT - the units of WHAT

Chromosomes carry GENES - the units of HEREDITARY STRUCTURE

Paired chromosomes separate WHAT of each other during WHAT

Paired chromosomes separate INDEPENDENTLY of each other during MEIOSIS

Around 1902, scientists noted the parallels between the behaviour of WHAT and the behaviour Mendel described in WHAT

Around 1902, scientists noted the parallels between the behaviour of CHROMOSOMES and the behaviour Mendel described in PEA PLANTS

Each chromosome contains many different WHAT - so, unlike Mendel suggests, NOT all WHAT can WHAT independently

Each chromosome contains many different GENES - so, unlike Mendel suggests, NOT all GENES can SEGREGATE independently
