For four o'clock flowers, flower color is a case of incomplete dominance. The gene for flower color has two alleles: red (R) and white (r). What is the percent probability that one offspring from a parent with red flowers a second parent with white flowers will have pink flowers?

0%

Explanation:

According to the question, the inheritance pattern of flower colour in four o'clock plants follow incomplete dominance i.e. one allele is not completely dominant over the other, and instead they form a heterozygous plant with a third intermediate phenotype (flower colour).

In this case, a four o'clock plant with genotype RR will have red flowers while a plant with genotype rr will have white flowers, Hence, they cross to form an all Rr genotype offsprings with pink flowers (since the red allele is incompletely dominant). Therefore, the percentage chance of having a red flower offspring from this cross is 0%, as it cannot occur.

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
