GENETICS (CHAPTERS 11 +14) At the end of this unit, you should be able to give thorough answers to the following questions: How does biological information pass from one generation to the next? How does genetics affect all other fields of biology? How is meiosis an essential component for maintaining life? Learning Targets 1. I know when a dominant or recessive allele will be expressed. (Section 11.1) o I can distinguish between a gene, allele and trait. o I can identify when a dominant or recessive allele will be expressed. o I know how the terms P, F1 and F2 are used to show different generations 2. I know that Punnett squares can be used to predict offspring. (Page 268) o I can predict the probability of a particular outcome, based on a Punnett square. o I can construct a Punnett square of a one-factor cross (monohybrid), given parental information. o I can interpret the results of a monohybrid Punnett square. o I know the rules of probability and how these rules relate to a phenotype of an offspring 3. I know how to determine the phenotype of an organism given its genotype. (Section 11.2) o I can identify a homozygous genotype. o I can identify a heterozygous genotype. o I can explain the difference between a homozygous and heterozygous genotype. o I can distinguish between a male and female genotype.

(Page 268) o I can complete a Punnett square of a two-factor cross (dihybrid), given parental information. o I can interpret the results of a Punnett square. o I know how the rule of independent assortment applies to the formation of gametes. (Section 11.2) o I can list the gametes produced by an individual, when given their genotype 5. I know the inheritance patterns of sex-linked disorders, codominance, incomplete dominance, and multiple alleles. (Section 11.3) o I can explain how sex-linked disorders are inherited. o I can identify other types of inheritance such as codominance, incomplete dominance, multiple alleles, and polygenic traits. o I can identify other types of inheritance such as codominance, incomplete dominance, multiple alleles, and polygenic traits.

I know how to analyze a karyotype. (Section 14.1) o I can identify a karyotype. o I can write the genetic notation for an individual, based on a karyotype. o I can determine the disorder of an individual, based on a karyotype. o I can describe the difference between autosomes and sex chromosomes. o I can analyze a karyotype to determine sex. 7. I know humans have different blood types due to multiple alleles o I can determine possible blood donors for each blood type o I can predict a baby’s blood type if I know the parent’s blood type o I know which blood types are dominant, recessive, and codominant o I can determine a person’s blood type if I know their genotype 8. I know how to analyze a pedigree. (Section 14.1) o I can state the genotype of an individual based on their information on a pedigree. o I can predict the probability that a particular individual will have a disorder, using my knowledge of sex-linked traits. o I can identify males and females in a pedigree. o I can determine whether an individual has a disorder, does not have a disorder or is a carrier for a disorder, based on a pedigree.

[Assessment Boundary: Assessment does not include the phases of meiosis or the biochemical mechanism of specific steps in the process.] LS3-3 Apply concepts of statistics and probability to explain the variation and distribution of expressed traits in a population. [Clarification Statement: Emphasis is on the use of mathematics to describe the probability of traits as it relates to genetic and environmental factors in the expression of traits.] [Assessment Boundary: Assessment does not include Hardy-Weinberg calculations.]
