Genetics Smores Project
By:Ethan Sandy, Bella Nunu
Who discovered Genetics and how did he do this?
The person who discovered Gregor Mendell. He studied pea plants.
Contrast the following terms: dominant/recessive; hetrozygous/homozygous; genotype/phenotype
Dominant/Recessive
Dominant alleles are the traits that mask the recessiveReccessive alleles are the traits that are masked
Hetrozygous/Homozygous
Hetrozygous means that the 2 alleles are diffrent (ex:Tt)Homozygous means that the 2 alleles are the same (ex TT, tt)
Genotype/Phenotype
Genotype is the alleles stated ex: TtPhenotype is the physically seen trait ex:Tall
Example of a punnett square
Genotype: 25% AA 50%Aa 25% aa Phenotype: 75% Auburn fur 25% Violet fur
Describe incomplete dominance and provide an example.
Incomplete dominance is where two dominant alleles fuse together to create a new allele.
Describe codominance and provide an example
Codominance is where there is a pattern where phenotypes of both homozygotes parentes are produced in heterozygous offspring so that both alleles are equally expressed.
What are multiple alleles and what are they used to detremine
Precense of more that two alleles for a genetic trait.
Describe and provide examples of sex-linked traits
traits controlled by genes located on sex chromosomes
