being heterozygous resulting in some sort of blending
the allele that is always expressed
the allele that can be masked by a dominant allele
Codominance

being heterozygous resulting in some sort of blending
the allele that is always expressed

Dominance
One form or variation of a gene
being heterozygous resulting in some sort of blending
the allele that is always expressed
the allele that can be masked by a dominant allele
Recessive
One form or variation of a gene
being heterozygous resulting in some sort of blending
the allele that is always expressed
the allele that can be masked by a dominant allele
Genotype
the genes of an organism
the visible trait or genes that are expressed in an organism
if the gene is carried on the X or Y chromosome
an organism that has different alleles -one dominant and one recessive
Phenotype
the genes of an organism
the visible trait or genes that are expressed in an organism
if the gene is carried on the X or Y chromosome
an organism that has different alleles -one dominant and one recessive
Sex-Linked
the genes of an organism
the visible trait or genes that are expressed in an organism
if the gene is carried on the X or Y chromosome
an organism that has different alleles -one dominant and one recessive
Heterozygous
the genes of an organism
the visible trait or genes that are expressed in an organism
if the gene is carried on the X or Y chromosome
an organism that has different alleles -one dominant and one recessive
Homozygous
an organism that has two of the same allele
a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring
The first set of parents in a test cross
A tool used to figure out the probability that an offspring will express a certain trait.
