Manx cats are distinctive because they do not have tails, their front legs are shorter than their rear legs and they often travel by hopping. These traits are controlled by a single gene. Manx cats are heterozygous for a dominant allele that causes these traits.
Explain what type of of cross is required to prove Manx cats are heterozygous for the gene?
How do I start?
So, if Manx cats are heterozygous for the tail trait - lets call the long tail "t" and the short tails "T" (they told you that the Manx gene is dominant and ...
Manx cats and issues related to the tail trait are studied.
