Genetics

=Genetics and Mendelian Inheritance=

Textbook Alignment
Although it will not be taught in the sequence given by the text, Unit 4 is about genetics.

Objectives:
Section 10.1 Define the terms: //gene, trait, allele, and inheritance// Distinguish between a homozygote and a heterozygote. Contrast dominance and recessiveness. Explain incomplete dominance and co-dominance. Convert a gentoype to a phenotype. Convert a phenotype to a genotype. Complete a monohybrid cross. Complete a dihybrid cross. Calculate genotypic ratios of offspring given a monohybrid or dihybrid cross. Calculate phenotypic ratios of offspring given a monohybrid or dihyrbrid cross.













Objectives:
Section 12.1 Interpret a pedigree Identify human genetic disorders caused by inherited recessive alleles. Predict how a human trait can be determined by a simple dominant allele.

Section 12.2 Distinguish between alleles for incomplete dominance and codominance. Explain the patterns of multiple allelic and polygenetic inheritance. Analyze the pattern of sex-linked inheritance. Summarize how internal and external environments affect gene expression.

=Pedigree Analysis= The use of pedigrees is introduced and explored in Chapter 12. ==

Objectives:
Covered in par in Chapters 11, 12, and 13 tackled as a group project. =Genetic Disorders= We will be studying and presenting genetic disorders in groups. Students will be assigned a role (see below) and will be responsible for contributing their part. These disorders are presented in part in Chapter 12 and other chapters in the text.



Each group must submit a copy of their group paper (hand written or typed in MS Word - see below).

Each student will also be responsible for taking notes and recording the information presented in their notes. Page numbers were noted so students can reference their book to check for accuracy.



All members of the group will answer questions asked by classmates upon conclusion of their group's presentation.

The following notes covers pedigrees and genetic disorders together.
