Trait

Recessive Allele

An allele that is masked when a dominant allele is present

How many parents are needed for asexual reproduction?

alleles

Some traits exhibit a large number of phenotypes because the traits are controlled by genes with many different

Dominant Allele

An allele whose trait always shows up in the organism when the allele is present.

Genotype

An organism's genetic makeup or allele combinations

Phenotype

An organism's physical appearance, or visible traits.

Heterozygous

Describes an organism with two different alleles for a trait.

Allele

Different forms of the same gene. A variation of a gene's nucleotide sequence (an alternative form of a gene).

Inheritance

The process by which physical and biological characteristics are transmitted from the parent (or parents) to the offspring

clone

What is the offspring from asexual reproduction called?

Somatic Cell

the chromosome has two different copies of the gene that controls the trait

Homozygous

Describes an organism that has two identical alleles for a trait

homo dominant
