Answer:

Gametes that will be produced are:

YST, YSt, YsT, Yst, yST, ySt, ysT, yst

Explanation:

From YySsTt, it is obvious that as there 3 type of genes.

The number of gametes = 2^{3} = 8

5 genes = 2^{5} = 32 genotypes

10 genes = 2^{10} = 1024 genotypes

20 genes = 2^{20} = 1048576 genotypes

cell organelles In this lab, you will try to view as many cell organelles as you can at different magnification levels. Write an
CaHeK987 [17]

Answer:

What is the effect of power/magnification on the frequency and size of organelles under a microscope?

Explanation:

Organelles within the cell are responsible for carrying out various functions. Some cells are more specialized than others, and may have particular organelles at a higher frequency, or showing a variation in size; sub-cellular structures become more visible at higher magnifications under the microscope.

Hypotheses:

  • organelle A's frequency decreases while B's frequency increases at higher magnifications
  • organelle A's size increases while B's size decreases at higher magnifications

<em />

<em>Dependent variables: size and frequency cell organelles</em>

<em>Independent variable:  power/magnification at low (x4), medium(x10) and high  (x40)</em>

<em>Controlled variables: Type of organelles, microscope used, cell examined, </em>

Method:

1. Examine the organelles A and B in a cell mounted on a slide; use the fine adjustment to focus on the cell.

  • Frequency:  What is the average number of organelle A versus B, seen at low (x4), medium (x10) and high (x40) magnifications?
  • Size: Measure the average diameter of organelle A versus B using an ocular micrometer at low, medium and high magnification.

2. Record and tabulate observations.
