Can I statements for Biology

This is something we always do in our school, as preparation for our exams and to be honest they seem to help me a lot, so I thought I might as well share them to see how helpful they are, so I would be grateful to hear any comments negative or positive and would like you to rate on how useful it as because if it is a positive outcome I can upload more for biology, physics and chemistry.

Thank you, hope they are useful.

B1: You and your genes
The inheritance of detailed information from each generation to the next is a important story
in science. For each of us, inheritance also raises questions about our own development. In this
module, you will learn the basic concepts of inheritance: genes as units of inheritance,…

8. can I explain that an allele can be dominant or recessive, and that: Y

a. an individual with one or both dominant alleles (in a pair of alleles) will
show the associated dominant characteristic

b. an individual with one recessive allele (in a pair of alleles) will not show…

1. Can I explain that a small number of disorders are caused by faulty Y
alleles of a single gene including Huntington's disease and cystic fibrosis?

2. Can I remember that disorders may be caused by dominant alleles (eg Y
Huntington's disease) or recessive alleles (eg cystic fibrosis)?

3. Can…

7. Can I explain how testing adults and fetuses for alleles that cause genetic
disorders hasimplications that need to be considered, including:

a. risk of miscarriage as a result of cell sampling for the genetic test

b. using results that may not be accurate, including false positives and false

4. Can I explain how clones of animals occur:

a. naturally, when cells of an embryo separate (identical twins)

b. artificially, when the nucleus from an adult body cell is transferred
to an empty unfertilised egg cell?

5. Can I describe that there are different types of stem cells:…
