The principle stating that during production of gametes, the two copies of each hereditary factors segregate so that offspring acquire one factor from each parent.

When an individual has 2 of the same allele whether it's dominant or recessive

Q.
A unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.

Q.
The set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
11

Q.
A form of dominance in which the alleles of a gene pair in a heterozygote are fully expressed thereby resulting in offspring with a phenotype that is neither dominant nor recessive.

Q.
When an individual has 2 different alleles-- one dominant, one recessive.

Q.
Someone who has two identical alleles for one gene trait
15

Q.
Males have one X chromosome and one Y chromosome while females have two X chromosomes. The X chromosome is much bigger than the Y chromosome so females can carry more genetic information.

Q.
When neither of the paired alleles completely dominates the other. The two alleles are combined. For example, a red flower combined with a white flower would make pink.
