BIO.3B Students will analyze and interpret data collected from probability calculations to explain the variation of expressed traits within a population.
BIO.3B.1 Demonstrate Mendel’s law of dominance and segregation using mathematics to predict phenotypic and genotypic ratios by constructing Punnett squares with both homozygous and heterozygous allele pairs.
BIO.3B.2 Illustrate Mendel’s law of independent assortment using Punnett squares and/or the product rule of probability to analyze monohybrid crosses. BIO.3B.3 Investigate traits that follow non-Mendelian inheritance patterns (e.g., incomplete dominance, codominance, multiple alleles in human blood types, and sex-linkage).
BIO.3B.4 Analyze and interpret data (e.g., pedigrees, family, and population studies) regarding Mendelian and complex genetic traits (e.g., sickle-cell anemia, cystic fibrosis, muscular dystrophy, color-blindness, and hemophilia) to determine patterns of inheritance and disease risk.
