Virtual Genetics

[brett86]

Hi everybody, just having trouble figuring this virtual genetics stuff out. I have figured out the numbers and ratio's but i dont know how to work out what kind of inheritance it is for the mutation type(autosomal, sex-linked, dominant, recessive, lethal) The numbers are as below. Also is there an easy way to tell what kind of mutation it is, eg. by looking at the observed results. Thanks for you help.
