NGSS.HS-LS3-1

When an organism has two of the same alleles - two dominant or two recessive alleles - its genotype is said to be this.

• Homozygous

• Phenotype

• Heterozygous

• Recessive Trait

When an organism has this type of genotype, it has two different alleles - one dominant allele and one recessive allele.

• Heterozygous

• Recessive Trait

• Dominant Trait

• Homozygous

This mathematical term is the likelihood/chance that a possible future event will occur.

NGSS.MS-LS4-4

When parents with two different traits have an offspring, this trait reappears in the second generation (i.e. their grandchildren) after disappearing in the first generation (i.e., their children).
