You are studying a cell line in in which one cell cycle takes approximately 24 hours. You perform FACS analysis on a population

of your dividing cells. Your cells are growing asynchronously meaning different cells are in different stages of the cell cycle. Your FACS analysis indicates that 1/3 of your cells have a DNA content of 2n. How long is the G1 phase in these cells?

Answer: 8hrs

Explanation:

G1 phase is the intermediate phase between the end if cell division and the beginning of DNA replication.

Thus to get the duration of the G1 phase = 1/3 × 24hrs = 8hrs

Do male and female offspring possess the same likelihood of carrying the colorblindness trait in their genotype
Katen [24]

Complete question:

Punnet squares for genes found in sex chromosomes are unique in that the pattern of inheritance of these traits is gender-specific. For example, examine the following Punnet square for color blindness, a trait found in the X chromosome (Y chromosome carry only a few genes but they do not possess enough coded information to initiate the development of the male).

Xcb represents the X chromosome carrying the color blindness trait. The allele for color blindness is recessive to the normal form of the gene (X).

Punnet square:

                                      Mother

                                Xcb             X

Father         X          X Xcb        X X

                  Y          Xcb Y        X Y

Do male and female offspring possess the same likelihood of carrying the colorblindness trait in their genotype?

Answer:

<em>YES. Male and female offspring </em><u><em>will have the same likelihood</em></u><em> of carrying the colorblindness trait in their genotype. </em>

Explanation:

Due to technical problems, you will find the complete explanation in the artached files.
