Father of genetics. Studied
traits in pea plants.

Gregor Mendel
2
Any characteristic that can be
passed be inherited from
parent to offspring.
3
Trait
4
Alternative forms of a trait.
5
Alleles
6
Section of chromosome (DNA)
that codes for a specific trait.
7
Gene
8
A diagram of the genetic
history of an individual: can
show how a trait is inherited
over several generations of a
family. (a genetic family tree)
9
Pedigree
10
Genotype of an individual with
two different alleles for a given
trait.
11
Heterozygous
12
Genotype of an individual with
two of the same alleles for a
given trait.
13
Homozygous
14
Alleles for a trait seperate
randomly and independently of
each other.
15
Law of Independent
Assortment
16
Each pair of alleles segregates
(seperates)during gamete
formation. Each gamete
contains one allele from each
pair.
17
The Law of Segregation
18
Occurs when neither allele is
dominant. They both have an
affect on the heterozygous
individual which shows a
phenotype between the two
homozygous phenotypes.
19
Incomplete Dominance
20
The genetic make-up of an
organism.
21
Genotype
22
The external appearance of an
individual determined by it’s
genotype.
