CMB1005/BMN1004 Strand D - Genetics: Gene Linkage Practical - Aims
The primary aim of this pre-practical work is to get you familiar with the tools, genetic concepts and ideas that you will need to complete the 'Hairy Tree Rat' practical and the post-practical assessment on Canvas.
In this practical you will:
- Learn how to construct Punnett Squares
- Further explore inheritance and genetic distance
Inheritance is based on the passing of
genes![](gifs/yellow.gif)
from organism to organism. Understanding how this process occurs, and how it is regulated, helps with our understanding of genetic diseases.
Punnett Squares![](gifs/yellow.gif)
are a very useful tool for understanding inheritance of genetic traits. With a
Punnett Square![](gifs/yellow.gif)
, which is essentially a matrix, you can work out how
genes![](gifs/yellow.gif)
can be divided between the
gametes![](gifs/yellow.gif)
and how these can be combined to give you the final
genotypes![](gifs/yellow.gif)
(and the
phenotype
IF you know the dominance relationships).
