Red-green color blindness is a sex-linked recessive trait in humans.  Two people with normal color vision have a color-blind son. What are the genotypes of the parents?

  A. Name the phase of Mitosis.   B. Plant or Animal?

The following questions are based on Figure 12.3.Figure 12.3Which number represents the genetic material of the cell going from diploid to haploid?

Which term describes centrioles beginning to move apart in animal cells?

In the cell cycle, what is the name given to the points at which the cell cycle is regulated before advancing to the next stage?

The following questions refer to Figure 17.2, a table of codons.Figure 17.2A possible sequence of nucleotides in the template strand of DNA that would code for the polypeptide sequence phe-leu-ile-val would be

For the following questions, match the key event of meiosis with the stages listed below. I. Prophase I V. Prophase II II. Metaphase I VI. Metaphase II III. Anaphase I VII. Anaphase II IV. Telophase I VIII. Telophase II Tetrads of chromosomes are formed; crossing over at the chiasmata occurs between sister chromatids.

Which of the following synthesizes short segments of RNA?

The following questions refer to the essential steps in meiosis described below.1. Separation of sister chromatids2. Alignment of tetrads at the metaphase plate3. Formation of four new nuclei, each with half the chromosomes present in the parental nucleus4. Separation of the homologues; no uncoupling of the centromere5. Synapsis; chromosomes moving to the middle of the cell in pairsFrom the descriptions above, which of the following is the order that most logically illustrates a sequence of meiosis?

After telophase II of meiosis, the chromosomal makeup of each daughter cell is
