Offspring produced by parents that differ in one or more traits are called

Hybrid

Explanation:

Two parents belonging to a species and having more than one varying traits are referred to as hybrids. For example –  

Let us suppose that two human beings vary in two different traits. One trait is skin color and the other trait is height.  

Let the allele for tall height be “T” and the allele for shot height be “t”

Similarly, let the allele for fair color be “F” and the allele for dark color be “f”  

Then the genotype of a true-breeding tall and fair person A would be TTFF

And the genotype of a true-breeding short and dark person B would be ttff

Since both the person A and B have two different traits, therefore they can be referred to as dihybrid

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
