An individual displays two dominant alleles but it is not known if that individual is homozygous dominant of heterozygous for those traits. that individual is crossed with another individual that is homozygous recessive for both traits. this genetic cross is referred to as a

test cross

Explanation:

To uncover the zygousity (whether homozygous or heterozygous) of the individual, apply test cross.

To do this: cross the individual (parent) with unknown trait with an individual with a known homozygous trait and observe the offspring.

A) If the unknown parent is homozygous dominant, all offspring will express the dominant phenotype.

B) However, if the unknown parent is heterozygous, half the offspring should be dominant and half recessive

answer: a) a compound microscope has a greater magnification ability than a simple microscope.

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.
