The physical expression of an organism’s genes is its:

In fruit flies, dominant gene “R” produces red eyes and recessive gene “r” produces white eyes.   Also, the R and r alleles are sex-linked (they are part of the X chromosome but not the Y chromosome or the autosomes).   Which mating below gives offspring that all have red eyes and all females are carriers of the white eyes gene?

In plant cells, cytokinesis includes:

Separation of the sister chromatids is a characteristic of this stage of mitosis:

Which is a phenotype?

Consider these events in mitotic cell division: Cleavage furrow forms. Nuclear envelope (membrane) breaks down. Sister chromatids separate. Chromatin condenses into chromosomes. Chromosomes align at the equator. Nuclear envelope (membrane) forms. Which event occurs the earliest?

Which about pluripotent stem cells is true?

The genetic makeup (or list of alleles) of an individual is the:

A true breeding dominant phenotype male and a true breeding recessive phenotype female mate in a simple Mendelian monohybrid cross. Which generation will have a genotypic ratio in which all the individuals are heterozygous?

The part of meiosis that is similar to mitosis is ________.
