You are studying 5 genes: a, b, c, d, and e. In an attempt to map them, you perform a series of two-point crosses with the resul

ts listed below. Select the appropriate gene order based on the results of your experiment.
a-b = 15 map units;

a-c = 21 map units;

a-d = 1 map unit;

b-c = 6 map units;

b-e = 2 map units;

c-d = 20 map units;

c-e = 8 map units;

d-e = 12 map units.

Answer:

Gene order will be- a,d,e,b,c

Explanation:

Gene mapping refers to the arrangement of genes on the chromosomes. The genes can be mapped on the chromosome by calculation the recombination frequency in the hybrid crosses.

The recombination frequency can be represented on the chromosomes to show the distance between the genes which is measured as centimorgan. 1 percent recombination is considered 1 cM.

In the given question, since the distance between the gene has been provided therefore the genes can be mapped on the chromosome.

This could be done in the following manner-

1. Take the highest value of distance- 21 m. u between a and c.

2. Now take c as a reference point and arrange the other distance measuring distance from the c.

3. On this basis- c-d, c-e and b-c can be plotted.

4. Now, plot other values taking an as a reference point and plot the values b-e, a-b, a-d.

5. the genes will be arranged in the order a,d,e,b,c.

Thus, a,d,e,b,c is the correct answer.

You need to start an experiment and the instructions are to mix 2 g of sodium bicarbonate with 50 ml of distilled water and then
Elodia [21]

You need a weighing balance to weigh out 2g of solid sodium bicarbonate and a measuring cylinder to measure out 50 mL of water. You need to ensure that you use a facemask during the experiment.

<h3>How do we carry out the experiment?</h3>

We know that we require apparatus to carry out a scientific experiment. The apparatus are those things that would help us to carry out the experiment that we want to do.

In this case, the activity is to  mix 2 g of sodium bicarbonate with 50 ml of distilled water and then mix the solution. You need a weighing balance to weigh out 2g of solid sodium bicarbonate and a measuring cylinder to measure out 50 mL of water.

Mutation is an important mechanism for evolutionary change. Which type of mutations contribute to evolution?
rodikova [14]
Adaptations are the result of evolution in different living organisms. This process occurs amazingly through gene mutation but it takes a very long period in time. Adaptation processes occur to help species survive and thrive in the ecological balance of life. Structural adaptations are physical features of an organism that adapted through time. An example of this are the bills of a bird and the fur of bears that they generally need for their survival; birds for hunting, and bears to protect them from low climate areas.
<span>
Functional or Behavioral adaptations refer to particular things that an organism or organisms do to survive. In the example above, behavioral adaptations that birds do is through certain bird calls and migration, while bears hunt during warmer seasons and hibernate during winter season. </span>
