What is an Allele?
What is the number of the chromosome that determines your sex?
23
Different forms of the same gene. A variation of a gene's nucleotide sequence (an alternative form of a gene).
Allele
An allele whose trait always shows up in the organism when the allele is present.
Dominant Allele
An organism's genetic makeup or allele combinations
Genotype
Describes an organism with two different alleles for a trait.
Heterozygous
Describes an organism that has two identical alleles for a trait
Homozygous
The process by which physical and biological characteristics are transmitted from the parent (or parents) to the offspring
Inheritance
An organism's physical appearance, or visible traits.
Phenotype
An allele that is masked when a dominant allele is present
Recessive Allele
the chromosome has two different copies of the gene that controls the trait
Somatic Cell
A characteristic that an organism can pass on to its offspring through its genes.
Trait
female coding
XX
male coding
XY
trait not determined by genes
acquired trait
Some traits exhibit a large number of phenotypes because the traits are controlled by genes with many different
