Last 12 Biology class for 2013

Team Excellence?

12 Biology revision

Dear Students

I hope your Biology revision is well underway and you are making good use of the long weekend. In class last week I mentioned two very good web pages that could help your preparation. They were No Brain too Small and Pass Biology.

Mr Edwards

Collaborative activity - Genetic Drift NZ Examples

Hi 12BIO students of Miss Meehan
Please find the link below to contribute your research idea (1 x Founder, 1 x Bottleneck) to the NZ examples list.
Click here and edit the table by adding your contribution. If table is fill, create a new row by clicking at the end.

What are linked genes?

Are you stuck on what is genetic linkage?

Normally when we talk about dihybrid crosses we are looking at two different traits where the genes responsible are on different chromosomes (i.e trait A on Chromosome 2 and trait B on Chromosome 7), but sometimes the two traits were are looking at are on the SAME chromosome. If this is the case then we will see a different inheritance pattern in the offspring - there will be less variation as the genes are inherited together as a pair.

The following page has some walk through videos that show meiosis of linked genes with and without crossing over. Click here.  (Sex linked traits are also discussed here, this may be interesting as an extension)

Population genetics simulation program

Use this simulation to see the effect of genetic drift. Try changing the features of the population and view the effect on the allele frequency.

Hi Students (and Caregivers)

We hope you are enjoying your holidays and are having a restful break. 

We also hope you are revising for the examinations and if you are interested in coming to a study class check out the following timetable.

These are open to all students regardless of your subject teacher and you are welcome to invite other HVHS students who might not have received this email. 

Classes will take place in B11/B12 (or check door for any room change on the day). 

It would be great if you could please reply by email to let us know which class/s you may attend so we have an idea of numbers.

The structure of these tutorials will be students working in small groups on model question/answers, completing workbook activities, plus come with any problems/questions you have on specific topics

Regards

Mr Edwards
