Heredity Vocab

Recessive

• trait of an organism that cannot be masked

• trait of an organism that can be masked by the dominant form of a trait

• physical appearance, visible traits

• any difference between individuals of the same species

Offspring of crosses between parents with different traits

• variation

• phenotype

• hybrid

• dominant

dominant allele

• These are inside the nucleus of your cells and hold your genetic material.

• The passing of traits from parent to offspring (children)

• If this type of allele is present, the trait it codes for will ALWAYS be seen

heredity

• This is when two dominant alleles are present in a gene.

• The physical appearance of a genotype (example: blue eyes, brown eyes)

• the passing of traits from parent to offspring

heterozygous

• This is when two recessive alleles are present in a gene.

• This is when a dominant allele and a recessive allele are present.

• This is when two dominant alleles are present in a gene.

When a child has a new genetic variation that it got from neither of its parents, it is called a ________________.
