 * Investigation 54: Investigating Human Traits ||  Collect and present individual and group data about human traits.

Inquire about whether or not human traits are inherited from parents or acquired by other means. ||  7.1.10. A dominant trait will be expressed if the organism is heterozygous or homozygous for the trait. A recessive trait will only be expressed if the organism is homozygous for the trait. ** (E) ** ||  C  || 50 minutes ||
 * Investigation 55: Plants Have Genes Too! ||  Prepare seeds resulting from a genetic cross to germinate for a later activity.

Predict the outcome of the colors of the offspring seedlings. ||  7.1.9. Alternative versions of genes (different alleles) account for variations in inherited characteristics (i.e., flower color). Pairs of chromosomes that have the same allele present on both chromosomes are homozygous. Pairs of chromosomes with different alleles are heterozygous. ** (E) ** 7.1.10. A dominant trait will be expressed if the organism is heterozygous or homozygous for the trait.

 * Investigation 56: Joe's Dilemma ||  Learn about a hereditary condition that may not show symptoms until later in life.
