Lab: Genetics of Canis murphius
In this lab, you will be investigating the genetic characteristics of a newly discovered animal -
Canis murphius.

You will need:  a coin to flip

Step #1 Legs:
Flip your coin and click on the appropriate genotype link below:
Heads: Shows dominant phenotype (L)

Genotype:  L_
Tails: Shows recessive phenotype (l)

Genotype:  ll
When the phenotype is dominant, we
know there is one dominant allele, but we
can't be certain there are two.  The other
allele might be a recessive.  So, we can't
write for sure what the second allele is in
this case.
When the phenotype is recessive, we know
that both alleles must be recessive so we
can write them both in this case.
