Although in reality the inheritance of cleft chin (e. g., the deep chin dimple seen in Ben Affleck) is slightly more complicated, for now let's assume that the presence or absence of a cleft chin is determined by one gene. By studying pedigrees, we know that no child possesses a cleft chin unless at least one parent does (either the mom or the dad). Hint: Based on that last statement, you should now know the mode of inheritance! What is it? (Remember Recessive traits can hide, but dominant traits never do!) (1) Cleft chin is a dominant trait. (2) Cleft chin is a recessive trait.

Cleft chin is a dominant trait

Explanation:

Single gene inheritance: From the description, cleft chin is a dominant trait if at least one parent has it. For a trait to be inherited in the recessive condition, both parents must have a copy each of that trait. But for this trait to be inherited from at least one parent, it has to be a dominant trait.

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
