2
The Father of Genetics

• Gregor Mendel

3
A segment of DNA on a chromosome that codes for a
specific trait.

• Genes

4
When genes in as gene pair are identical, the
organism is

• Purebred

5
The passing of traits from parent to offspring.

• Heredity

6
the product of reproduction, a new organism
produced by one or more parents.

• Offspring

7
The Gene makeup of an organism

• Genotype

8
What are the 4 parts of a genotype

• Number
• Letters
• Name
• Percent

9
The Physical appearance of an organisms

• Phenotype

10
Name the 3 parts of a Phenotype

• Number
• Physical appearance (what it looks like)
• Percent

11
Characteristic of an organism

• Trait

12
The different forms of a gene

• Alleles

13
Organism that has genes that are differenthint
Tt

• Hybrid or Heterozygote

14
A rod-shape structure

• Chromosome

15
Genes that mask other genes

• Homozygote Recessive

16
An allele whose trait always shows up in an
organism

• Homozygote Dominate
