Alleles
Different forms of a gene
Genetic Drift
Changes in gene within a population
Probability
The likelihood that a particular gene will occur
Heterozygous
Having two different alleles for a particular gene
Homozygous
Having the same alleles for a particular gene
Dominant
Is the gene that is dominant, and is expressed (always) by a capital letter.
Recessive
Is the gene that is recessive, and is expressed (always) by a lowercase letter.
Genotype
Your genetic makeup (you can't see your genotype).
Phenotype
Your physical traits (what you see on the outside)
Mendel's Principal Genetics
In independent assortment it helps account for the many genetic variations observed in plants, animals, and other organisms - even when they have the same parents.
Co-dominance
When two traits are expressed at the same time.
Incomplete Dominance
The mixing of two genes together.
Diploid Cell
Diploid cell would have 46 chromosomes. 2n= Diploid (somatic, body)
Haploid Cell
Haploid cell would have 23 chromosomes. n= Haploid (sex cell, sperm/egg).
