Genetics+and+Variation+,+Evolution+(Bio+2.3)

Hi all,

For this Achievement Standard I will be putting up resources to accompany your text book for each Specific Learning Outcome (SLO).

Resource material containing the SLOs and their requirements:

=__**GENETICS AND VARIATION SLOS**__= 1 Describe the structure of DNA and its role in the cell. 2 Describe the structure of a chromosome. (See your txtbook or go to []) 3 Define the terms autosome and sex chromosome. (Student handout). (Answers)

4 Define the terms homologous, haploid / monoploidand diploid with respect to chromosomes 5.Describe the process of DNA replication.(Information sheet). (Worksheet) 6.Describe Mitosis and Meiosis and explain the importance of these processes. (Worksheet)

7.Describe independent assortment and segregation and explain the relevance of these to variation., 8. Describe the process of crossing over within meiosis and the impact of this on the production of recombinant chromosomes within the gametes., 9. Define the term mutation and identify ways in which mutations may affect an organism.,

10. Differentiate between the effect of gametic and somatic mutations.

11. Describe the principles of dihybrid inheritance patterns and use these to predict the outcome of dihybrid inheritance problems.

12. Use core knowledge to give reasons for genetic variation and change

13. Show understanding of genetic variation and change by using the core knowledge to link ideas e.g. in justifying, relating, evaluating, comparing and contrasting or analysing.
