Product Description
This 67-slide powerpoint presentation covers 'Topic 3.4 - Inheritance' in the 2016 IB Biology curriculum. Each slide includes the specific learning objective as well as key vocabulary that students should note.

The topic has been divided into five sections:

     • A - Inheritance & Alleles
     • B - Monohybrid Crosses
     • C - Diseases & Sex-Linkage
     • D - Pedigrees
     • E - Genetic Mutations

The presentation itself contains minimal information as it is intended to be used with teacher guidance. There are sometimes 'Video' throughout which link to relevant and informative YouTube content. The slides are formatted to be visually pleasing and to also print well for handouts or revision. Please see the preview file (first 8 slides) for an idea of the aesthetic and level of detail in the presentation. The relevant 'Essential Knowledge' can be found below.

Suggested Use:

I have had success using these presentations to review topics after students have been exposed to the material at home. I typically have the class read relevant material (book, site, etc.) and then watch the videos the day before introducing a topic. During the class period, I use the slides to structure the discussion around the IB Bio Understandings. The remaining class time is spent reinforcing the knowledge or working on activities, written test practice, or nature of science.

**These presentations are based on the IB Biology Course Guide and do not follow any textbook

As always, please let me know if you have any suggestions for improvements. These are always a work in progress!

==============================

Learning Objectives:

U1: Mendel discovered the principles of inheritance with experiments in which large numbers of pea plants were crossed.
U2: Gametes are haploid so contain only one allele of each gene.
U3: The two alleles of each gene separate into different haploid daughter nuclei during meiosis.
U4: Fusion of gametes results in diploid zygotes with two alleles of each gene that may be the same allele or different alleles.
U5: Dominant alleles mask the effects of recessive alleles but co-dominant alleles have joint effects.
U6: Many genetic diseases in humans are due to recessive alleles of autosomal genes, although some genetic diseases are due to dominant or co-dominant alleles.
U7: Some genetic diseases are sex-linked. The pattern of inheritance is different with sex-linked genes due to their location on sex chromosomes.
U8: Many genetic diseases have been identified in humans but most are very rare.
U9: Radiation and mutagenic chemicals increase the mutation rate and can cause genetic diseases and cancer.
A1: Inheritance of ABO blood groups.
A2: Red-green colour blindness and hemophilia as examples of sexlinked inheritance.
A3: Inheritance of cystic fibrosis and Huntington’s disease.
A4: Consequences of radiation after nuclear bombing of Hiroshima and accident at Chernobyl.
S1: Construction of Punnett grids for predicting the outcomes of monohybrid genetic crosses.
S2: Comparison of predicted and actual outcomes of genetic crosses using real data. **
S3: Analysis of pedigree charts to deduce the pattern of inheritance of
genetic diseases.

**This learning objective is omitted from the presentation at is better explained using full data sets and chi-squared practice problems.
