In sweet peas, dominant alleles C and P are necessary for colored flowers. In the absence of either (__ pp or cc __) or both (cc pp), the flowers are white. What the phenotypic ratios be for the cross of Cc pp x cc Pp?

Which phase(s) of meiosis occur in a similar manner to mitosis?

Spindles are ___.

During ____, microtubules fasten the cell’s chromosomes to the spindle poles.

In both mitosis and meiosis II, ____________.

In garden peas, one pair of alleles controls the height of the plant, and a second pair of alleles controls flower color. The allele for tall (D) is dominant to the allele for dwarf (d), and the allele for purple (P) is dominant to the allele for white (p). A tall plant with purple flowers crossed with a tall plant with purple flowers produces 3/4 tall purple and 1/4 tall white. What is the genotype of the parents?
