1

______________   - a population that breeds true for a particular trait.

1

Phenotype - literally means "the form that is shown"; it is the outward, _______  _______  of a particular trait

1

Dominant - the allele that _______  itself at the expense of an _______  allele.

1

Recessive - an allele whose _______  is _______  in the presence of a dominant allele.

1

Allele - one _______ _______ of a given allelic pair; tall and dwarf are the alleles for the height of a pea plant; more than two alleles can exist for any specific gene, but only two of them will be found within any individual.

1

Allelic pair - the combination of _______ _______  which comprise the gene pair

1

Homozygote - an individual which contains only one allele at the allelic pair; for example DD is homozygous _______  and dd is homozygous _______ ; pure lines are homozygous for the gene of interest

1

Heterozygote - an individual which contains one of _______ _______  of the gene pair; for example the Dd heterozygote

1

_______  - the specific allelic combination for a certain gene or set of genes

Mendel discovered that the traits we inherit, like eye color or height, are determined by something he called genes. He found that each parent has a pair of genes for each trait in every cell. When two parents have a baby, the baby gets one gene for a trait from each parent. Each gene can be a dominant or a recessive type. When the parents' genes combine to make a baby, they mix together randomly, so it's like flipping a coin to see which gene the baby gets for each trait. How is this concept presented on the webpage: Sequence order below

Each parent has a gene pair in each cell for each trait studied. The F1 from a cross of two pure lines contains one allele for the dominant phenotype and one for the recessive phenotype. These two alleles comprise the gene pair.
One member of the gene pair segregates into a gamete, thus each gamete only carries one member of the gene pair.
The hereditary determinants are of a particulate nature. These determinants are called genes.
Gametes unite at random and irrespective of the other gene pairs involved
