Cats can have long tails (LL) or have no tail, which is called a bob tail cat (NN).  The intermediate tail length, medium, is a result of the heterozygous condition. Cross a long tail cat with a medium tail cat.  Give the genotype and phenotype percentages.

Explanation:

Fish are able to breathe underwater at birth because they have gills. The fish life cycle shows that the newly hatched larva is able to survive underwater. The fish also show paired fins, which is a characteristic of fish. The frog life cycle shows the organism going through metamorphosis, changing from an aquatic larva to a terrestrial adult. For this transition to happen, the larva needs to develop lungs. This metamorphosis is common in amphibians.
