Father of genetics. Studied traits in pea plants.
2
Gregor Mendel
3
Any characteristic that can be passed be inherited from
parent to offspring.
4
Trait
5
Alternative forms of a trait.
6
Alleles
7
Section of chromosome (DNA) that codes for a specific trait.
8
Gene
9
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)
10
Pedigree
11
Genotype of an individual with two different alleles for a given
trait.
12
Heterozygous
13
Genotype of an individual with two of the same alleles for a
given trait.
14
Homozygous
15
Alleles for a trait seperate randomly and independently of
each other.
16
Law of Independent Assortment
17
Each pair of alleles segregates (seperates)during gamete formation. Each gamete
contains one allele from each pair.
18
The Law of Segregation
19
Occurs when neither allele is dominant. They both have an
affect on the heterozygous individual which shows a
phenotype between the two homozygous phenotypes.
20
Incomplete Dominance
21
The genetic make-up of an organism.
22
Genotype
23
The external appearance of an individual determined by it’s
genotype.
24
Phenotype
