Chromosomes are copied during what stage of the cell cycle?

Figure 11.5   This illustration shows _________________.

In horses, black coat color is influenced by the dominant allele (B), and chestnut coat color is influenced by the recessive allele (b). Trotting gait is due to a dominant gene (T), pacing gait to the recessive allele (t). If a homozygous black trotter is crossed to a chestnut pacer, which phenotype will be the most common in the F2 generation? This is a dihybrid cross, use the 5 step method to solve the problem.

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 latest?

An organism’s phenotype is determined by the specific combination of inherited __________.

In a duplicated eukaryotic chromosome, sister chromatids are joined at a region called the:

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

In plant cells, cytokinesis includes:

The following genes in Ogres have been described and analyzed: T= allele for two-headedness (dominant) t= allele for one head (recessive) H= allele for hairy body (dominant) h= allele for non-hairy body (recessive) B= allele for brown eye color (dominant) b= allele for red eye color (recessive) A two-headed (homozygous), red–eyed ogre male marries a one-headed, brown-eyed (heterozygous) wife.  What is the expected phenotypic ratio of their offspring?

All are true about mitosis except:
