How does the genetic makeup of the skin cells differ from the genetic makeup of the of the gametes?
igor_vitrenko [27]

The cells of skin are somatic cells undergo mitosis while gametes are germ cells are and undergo meiosis.

Explanation:

The cells of the skin are somatic cells while the gametes are the germ cells which become haploid.

The cells of the skin undergo mitosis for the growth and repair process.

The germ cells or gamete undergo meiosis to produce haploid cells.

The skin cell when undergoes mitosis forms 2 diploid cells and gametes undergoes meiosis to form haploid cell.

The haploid cell on fusing with sperm or ovum becomes diploid by making a zygote.

The number of chromosomes in skin cell or somatic cell have complete set of chromosomes i.e. 46 in human while the cells of gamete will be half the chromosome as 23.

The half information of the individual is present in gamete whereas skin cell have full information.

a mammalian stem cell line has a doubling time of 24 hours. if you start with 350,000 of these cells, approximately how many cel
dedylja [7]

After 60 hours of growth, there is approximately 2 million cells.

Let y represent the number of cell after x hours.

The bacteria doubles every 24 hours, also there are initially 350000 cells hence:

y=350000(2)^\frac{x}{24}

The number of cells after 60 hours is:

y=350000(2)^\frac{x}{24}\\\\y=350000(2)^\frac{60}{24}\\\\y = 1979899

Therefore after 60 hours of growth, there is approximately 2 million cells.

A man with homzy type A blood and a woman with heterozygous type B blood want to know the probability of having a child with typ
Viktor [21]

Answer:

\frac{1}{2}

Explanation:

Homzy. type A blood = AA

Heterozygous type B blood = Bb

Punnett square

<u>      |  B   |  b  </u>

<u>   A | AB | Ab</u>

<u>   A | AB | Ab </u>

The ratio is = 2:2 = 1 : 1

The total number of outcomes are 4

The number of AB are 2

Thus the probability is \frac{2}{4} = \frac{1}{2}
