Genetic variation Chapter 8 ESA
In this section, you will be focusing on Genetic biodiversity, Mutations as sources of new alleles, and mutations that can occur during meiosis.
Please read chapter 8 and then watch the following videos that will support your learning.
Ameoba sisters Revision ( From year 11 science)
Genetic variation and mutations.
Crossing over, Independent assortment and segregation
Please complete the questions at the end of chapter 8.
Monohybrid inheritance.
Essentially this is a continuation of year 11 genetics. Read and complete chapter 9, although this should be pretty familiar to you if you have done genetics in level one science.
Long Version ( for those who have not done genetics before) Monohybrid inheritance
Short version ( for those familiar with monohybrid genetics) Monohybrid genetics
Dihybrid crosses
Dihybrid crosses are when more that one gene in involved. There are 16 possible outcomes for a dyhybrid cross as opposed to 4 outcomes for a monohybrid cross. Please what the video showing a dyhrid cross and then complete chapter 9 and 10 in the ESA book.
