Father of genetics. Experimented with pea plants and discovered law of dominance
diagram showing the gene combinations that might result from a genetic cross
To breed two individuals
Specific characteristic that varies from one individual to another
Trait that is passed from parent to offspring
The different forms of a gene.
trait that will show up in an organism's phenotype if gene is present
trait of an organism that can be masked by the dominant form of a trait
The particular alleles at present in an organism
Having two identical alleles for a trait
for example: HH or hh
Having two different alleles for a trait
for example: Hh
A relationship in which one allele is completely dominant over another
creates a BLENDED phenotype; one allele is not completely dominant over the other
creates a phenotype in which BOTH alleles for a gene are fully expressed.
