What is a Gene?
Segment of DNA that is the code to create a particular protein. These proteins help define are traits.
Different possible codings or varients of a particular gene.
An allele that can only be expressed when paired with the same reccesive allele.
Only the dominat allele is expressed as the phenotype.
What is an Allele?
A dominant allele paired with a reccesive allele.
Both alleles are dominant and expressed as a blended phenotype.
Different possible codings or varients of a particular gene.
A segment of DNA that is the code to create particular protein.
What does Homozygous mean?
Both alleles are different
Both alleles are the same
Genes in the DNA
Two mixed alleles
What is a Phenotype?
How the DNA is formed
Two paired alleles
A dominat gene overpowering a reccesive one
How the trait is expressed
What is a genotype?
Two of the same alleles
A specific combo of alleles.
A type of gene
Codings and varients of a gene
What does heterozygous mean?
Both alleles are different.
Both alleles are the same.
How a trait is expressed.
What a gene does.
What does dominant mean?
The dominant trait overpowers the reccesive one.
Both alleles are different
When a dominant allele is paired with a reccesive allele, the dominant trait is expressed
Both alleles are the same.
What does reccesive mean?
When a dominant allele is paired with a reccesive allele, the dominant trait is expressed
Both alleles are different
Both alleles are the same.
An allele trsit that can only be expressed when paired with the same reccesive allele.
What does a punnet square do?
It is a system for tracking possible offspring genotypes.
When a dominant allele is paired with a reccesive allele, the dominant trait is expressed
It is a box that you use to find ancestors genes.
It is a syatem for tracking possible offspring phenotypes.
What is a purebred?
It comes from a line of genes of the exact same origin.
When a dominant allele is paired with a reccesive allele, the dominant trait is expressed
It can be considered homozygous
A certain combo of alleles.
What is a hybrid?
When a dominant allele is paired with a reccesive allele, the dominant trait is expressed
It comes from a line of mized genes.
A certain combo of pure genes.
It can be considered heterozygous
What does complete dominance mean?
In a heterozygous genotype, only the dominant allele is expressed as the phenotype.
In a heterozygous genotype, only the reccesive alle is expressed as a phenotype.
Example: A reccesive white cat mates with a dominant black cat, and in their litter, their is only black cats.
Example: A reccesive white cat mates with a dominant black cat, and in their litter, their is only white cats.
What does co-dominance mean?
It´s not a blend, but a mix, of both parents in the child.
There is a blend of both parents in the child.
In a heterozygous gentype, both alleles are dominant and are expressed equally as the phenotype.
The opposite of dominance, menaing reccesive.
What does incomplete dominance mean?
Incomplete dominance means not fully domiant, so the opposite color of the dominant genptype.
There is a blend of both parents in the child.
There is a mix, not a blend, of the phenotype in the child.
In a heterozygous genotype both alleles are expressed as a phenotype that looks like a blend of both parents.
What is an environmentally influenced trait?
Example: If you had two bunnies, and put one in the desert to live and the other in the snow, they would grow up looking completley different from one another.
A trait that your environment influences, like your personlity.
Something influenced by the environment around them.
A pair of twins who look different from eachother.
What is a mutation?
An error in a reccesive gene
A mutant monster
An error in a dominant gene.
An offspring gene that has an allele that neither parent gave to them. This happens due to a mistake when copying DNA for new cells.
