Unit 4 – Inheritance Schedule
Learning Targets
1. I will compare asexual and sexual reproduction.
2. I will interpret and predict patterns of inheritance including the following: dominant, and recessive traits,
multiple alleles, polygenic inheritance, sex-linked traits, independent assortment, test cross, pedigrees, and
Punnett Squares.
Factual Knowledge – Recognize and Recall the definition of the following terms.
1. Chromosome – threadlike structure within the cell nucleus that contains the genetic material (DNA) that is passed
from one generation to the next
2. Diploid – two of each kind of chromosome; one from each parent (2n)
3. Haploid – one of each kind of chromosome; gametes (1n)
4. Karyotype – picture of a person’s chromosomes used to determine sex and if disorders are present
5. Asexual reproduction - the production of offspring in which only one parent is required and the offspring are
genetically identical to the parent (draw budding or binary fission)
6. Interphase - time during which a cell grows in size, makes more organelles, and replicates chromosomes
7. Mitosis - process through which the nucleus divides in two; each new cell receives a complete set of chromosomes
8. Sexual Reproduction – reproduction in which two parent cells join together to form a new individual with a genetic
makeup that is different from either parent
9. Meiosis – a process of cell division in a sexually reproducing organisms that divides half the number of
chromosomes in reproductive cells; creates haploid cells
10. Crossing over/genetic recombination - homologous chromosomes become so close that they exchange genetic
information
11. Gene – a segment of DNA that codes for a protein and that determines a single trait
12. Allele – two forms of a gene
13. Dominant – stronger of the two genes expressed as a hybrid; represented by a capital letter
14. Recessive – gene that shows up less often in a cross; represented by a lower case letter
15. Genotype – gene combination for a trait
16. Phenotype – the physical feature resulting from a genotype
17. Homozygous – gene combination involving 2 dominant or 2 recessive genes
18. Heterozygous – gene combination of one dominant and one recessive allele
19. Pedigree – a chart used to trace the inheritance of a specific trait through several generations in a family
20. Incomplete dominance – blending of traits; one allele is not completely dominant over another
21. Codominance – both alleles contribute to the phenotype
22. Multiple alleles – three or more alleles code for a trait
23. Polygenic traits – trait controlled by two or more genes
24. Sex linked trait – a trait carried by an allele on a sex chromosome

Analyze how cells grow, perform their jobs, and reproduce in terms of interphase, mitosis, and cytokinesis.
Summarize the steps of mitosis and how this creates two (2) identical daughter cells.
Describe how animal cells use specialized organelles (centrioles) to aid in cell division.
Differentiate between the multi-factorial causations of cancer including the roles of genetics and environment.
Describe how the process of meiosis promotes genetic diversity for sexually reproducing organisms.
Sequence the steps of meiosis and understand the importance of crossing over, reduction and division.
Describe the patterns of basic Mendelian inheritance including dominant and recessive traits.
Analyze the possible outcomes of a given genetic cross using phenotypic and genotypic ratios.
Determine how to perform a test cross to determine an unknown recessive genotype.
Summarize Mendel’s Principles / Laws of Inheritance for 1 factor (Monohybrid) cross.
Differentiate between and solve for various types of complex inheritance including incomplete, codominance,
multiple alleles, and polygenic traits.
12. Describe how non-disjunction, failure of chromosomes to separate properly, promotes chromosomal disorders.
13. Identify and describe the inheritance pattern of human genetic and chromosomal disorders.

Interpret Human Karyotypes to verify the sex and possible disorders of an individual.
Correctly sequence pictures of mitotic & meiotic phases and describe the events occurring in each of the stages.
Perform various Punnett Square crosses to calculate phenotypic and genotypic ratios.
Complete Pedigrees of various individuals over generations to determine the inheritance of a trait or disorder.
