Question

some traits, such as heart disease, seem to skip generations from grandparent to grandchild. what is true about carriers of a trait? possible points: 1 their shapes are shaded on a pedigree they will show/display the trait they carry a hidden recessive allele they inherit two recessive alleles from their parents

Explanation:

Carriers of a recessive - trait carry a hidden recessive allele. They do not show the trait themselves because they also have a dominant allele that masks the recessive one. Inheritance of recessive traits can skip generations as seen in the case of heart disease mentioned. For an individual to display a recessive trait, they must inherit two recessive alleles (one from each parent).

Answer:

they carry a HIDDEN recessive allele
