Around 40% of cats with white fur and blue eyes are deaf.

The gene responsible is pleiotropic means that one gene responsible for their deafness controls and affects multiple unrelated characteristics.

Pleiotropic gene action is what occurs when one gene affects two or more unrelated phenotypic characteristics or traits. An example of pleiotropic gene action occurs in Marfan syndrome (a human hereditary disorder). Marfan syndrome is caused as a result of a mutation in one gene which affects multiple features in the growth and development aspects such as height and the heart function.

Waves are folds of water cause by the gravitational pull of the moon.

AL has a pet cat. one day he observes that it is scratching and urinating on tree trunks in his yard. what behavior is al's cat

Leokris [45]

The answer is C=territoriality
This is so because Al's cat may have seen another cat in his 'home'. Cats don't like it when other cats trespass into their territory, so this is a way of marking it.
