The two members of a gene pair (alleles) separate from each other in the formation of gametes. Half the gametes carry one allele, and the other half carry the other allele.
Genes for different traits assort independently of one another in the formation of gametes.
This law states an organism has two different alleles for a trait and the allele that is expressed in the phenotype, masking the expression of the other allele is said to be dominant.
This is a form of a gene that is hidden by another, dominant, form of the same gene.
A cross between organisms with two different phenotypes produces offspring with a third phenotype in which both of the parental traits appear together. Blood type AB.
This is a trait that is a blend of the dominant and recessive gene: tall X short = medium height

Here are the terms that match each statement, with short definitions/examples:

- The two members of a gene pair (alleles) separate from each other in the formation of gametes. Half the gametes carry one allele, and the other half carry the other allele.
- Term: Law (Principle) of Segregation — during meiosis allele pairs separate so each gamete gets one allele.

- Genes for different traits assort independently of one another in the formation of gametes.
- Term: Law (Principle) of Independent Assortment — alleles of different genes are distributed independently to gametes (when genes are on different chromosomes or far apart).

- This law states an organism has two different alleles for a trait and the allele that is expressed in the phenotype, masking the expression of the other allele is said to be dominant.
- Term: Principle (Law) of Dominance — one allele (dominant) masks the effect of the other (recessive) in a heterozygote.

- This is a form of a gene that is hidden by another, dominant, form of the same gene.
- Term: Recessive allele — an allele whose effect is masked in a heterozygote.

- A cross between organisms with two different phenotypes produces offspring with a third phenotype in which both of the parental traits appear together. Blood type AB.
- Term: Codominance — both alleles are fully expressed in the heterozygote (e.g., IA and IB → AB blood type).

- This is a trait that is a blend of the dominant and recessive gene: tall × short = medium height.
- Term: Incomplete dominance — heterozygote shows an intermediate phenotype (a blend) between the two homozygotes.
