Modern Biology
Unit 6 Genetics Learning Targets
1. Genotype & Phenotype Relationships
a. I can explain how a multicellular organism develops from a zygote.
b. I can explain how phenotype and genotype are related.
c. I can explain how DNA and proteins relate to genetics.
Vocabulary: genotype, phenotype, zygote, fertilization, homozygous, heterozygous
2. Mendel’s Laws of Genetics
a. I can summarize and apply Mendel’s law of dominance.
b. I can summarize Mendel’s law of segregation and state when segregation occurs during meiosis.
c. I can summarize Mendel’s law of independent assortment and state when independent assortment occurs in meiosis.
Vocabulary: gene, allele, dominant allele, recessive allele,
law of independent assortment, law of segregation, law of dominance
3. Mendel’s Laws & Punnet Squares
a. I can use Punnett squares to perform monohybrid and dihybrid crosses.
b. I can calculate phenotypic and genotypic ratios from Punnet squares.
c. I can determine the genotype of a dominant organism of unknown parentage using a test cross.
Vocabulary: Punnett square, monohybrid cross, dihybrid cross, true-breeding,
P generation, F1 generation, F2 generation, testcross
4. Punnet Squares & Probability
a. I can explain why half of my DNA comes from each parent.
b. I can use the laws of probability to predict if offspring will be homozygous or heterozygous.
Vocabulary: probability
5. Beyond Mendelian Genetics
a. I can state why linked genes and sex-linked genes don’t follow Mendel’s laws.
b. I can use a Punnett Square to determine genotypes and phenotypes of traits following other inheritance patterns
(incomplete dominance, codominance, multiple alleles, and sex-linked)
c. I can explain the inheritance of ABO blood groups.
Vocabulary: polygenetic traits, multiple alleles, incomplete dominance, codominance, sex-linked traits
6. Pedigrees & Probability
a. I can analyze a pedigree and determine which inheritance pattern it shows: autosomal dominant, autosomal recessive,
sex-linked dominant, or sex-linked recessive.
b. I can use a pedigree to determine the phenotypes and genotypes of individuals in the pedigree.
c. I can use a pedigree to determine the probability of genotypes and phenotypes of individuals in the pedigree.
Vocabulary: pedigree
7. Summary
a. I can explain how segregation and probability determine which alleles will be in a gamete.
