Description
•
Students will be able to complete a monohybrid cross using a punnett
square for the following types of inheritance patterns: multiple allelic
and sex-linked, analyzing the cross to determine the phenotypes and
genotypes of the offspring (20%).
•
Students will be able to complete a dihybrid cross using a punnett
square for a simple dominance inheritance problem, analyzing the
punnett square to determine the traits of the offspring and producing
the correct genotypic and phenotypic ratios (5%).
•
Students will be able to identify/define the following terms: genetics,
heredity, homologous, heterozygous, pure, hybrid, trait, allele,
dominant, recessive, genotype, phenotype, autosome, sex-linked,
multiple allelic, Codominant and incomplete dominance.
•
Students will be able to complete a monohybrid cross using a punnett
square for the following types of inheritance patterns: simple
dominance, Codominant and incomplete dominance and analyze the
punnett square to determine the traits of the offspring—using the
genotypic and phenotypic ratio’s where appropriate.
•
Students will be able to analyze a pedigree to determine if the trait
being studied is dominant or recessive, sex-lined or Autosomal and be
able to determine the possible genotypes of the individuals
represented in the pedigree.
