Aheritable trait is one that a heritable trait is one that is determined at least in part by genes passed from parents to offspring. is dominant and hence is always inherited. is determined by genetic information encoded in proteins. an organism acquires during its lifetime and passes on to its offspring.

A heritable trait is one that is determined at least in part by genes passed from parents to offspring.

Explanation:

A heritable trait is the one which is passed from parents to offspring. While environmental factors can still have an effect on such traits, they are at least in part determined by the genes passed on from the parents. They are not always inherited specially if they are recessive.

Heritable traits are passed on through the genetic information stored in germ cells. If a trait is acquired during lifetime of an organism and was not present when the organism was born, such a trait wont be passed on to the next generation and wont come under heritable trait. For example if mice tails are cut for ten generations, the mice born in eleventh generation would still be born with tails.

the correct answer is sex-linked recessive.

i just took the test

in the year 2850, humans successfully colonized mars. the martian modules that were constructed could hold only a small population of people. it is now a century later, and the population on mars has grown to 600 people. of the current mars population, 45 people express the recessive phenotype for phenylketon- uria (pku) syndrome (pp genotype).
