Mendel concluded that...
two factors- one from each parent- controls each trait
one factor controls each trait
pea plants are quick
two factors- one from each parent- controls each gene
(a) contain genetic information that controls traits
chromosomes exist in _________- one from each ______________.
pairs (1)
parent (2)
offspring (2)
triplets (1)
What did Mendel study?
pea plants
corn
potatoes
flowers
Mendel used peas to study because :
They reproduce quickly
Could control which pairs of plants reproduce
Easily observable traits
They are big
Could control their colors
