Genetics

Definition

 

 

 

 

Branch of biology that studies heredity

Term

 

 

 

 

Heredity

Definition

 

 

 

 

Passing on of characteristics from parents to offspring

Term

 

 

 

 

Allele

Definition

 

 

 

 

Available forms of a gene - you get one from your mom and one from your dad for a total of 2 per gene.EX for the gene eye color the available alleles are:brown,blue,green,red,gray,black 

Alleles can be dominant or recessive



Term

 

 



Dominant

Definition

 

 

 

 

This form always appears-represented by a capital letter

 

Term

 

 

 

 

Recessive 

Definition

 

 

 

 

This form will not show up if paired with a dominant allele- this form will only show up if paired with another recessive allele- represented by a lower case letter

Term

 

 

 

 

Geneotype

Definition

 

 

 

 

The two letters representing which alleles are present- can only be RR,Rr and rr

Term

 

 

 

 

Homozygous

Definition

 

 

 

 

Refers to the RR and rr genotypes meaning the same 2 alleles are presented also called purebred,homozygous dominant-RR-means 2 dominant alleles are present homozygous recessive-rr- means 2 recessive alleles are present

Term

 

 

 

 

Heterozygous

Definition

 

 

 

 

refers to the Rr genotype meaning one of each type of allele is present- also called hybrid

Term

 

 

 

 

Phenotype

Definition

 

 

 

What the genotype looks like,the physical apperence of a gene

 

Brown eyes are dominant (R) and blue eyes are recessive (r)

 

Term
