Biology
1 answer:
MatroZZZ [7]2 years ago
3 0

Answer:

Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.

In the table on the right, observe Krakauer's formula for benefit to dominant male. What is the benefit, B? calculate the value
Mashcka [7]

The table is an illustration of two-way table, and the value of the cost to net benefit to subordinate male is 0.1

<h3>The value of the benefit</h3>

From the table, the Krakauer's formula for benefit (B) is:

B = Offspring per dominant male - Offspring per solo male

The question has missing parameters, so we make use of the following assumed values:

  • Offspring per dominant male = 7
  • Offspring per solo male = 2

So, we have:

B = 7 - 2

B = 5

Using the assumed values, the value of the benefit is 5

<h3>The cost to subordinate male</h3>

The Krakauer's formula for cost (C) is:

C = Offspring per solo male - Offspring per subordinate male

Given that subordinate male never reproduce, the equation becomes

C = Offspring per solo male - 0

C = Offspring per solo male

Using the assumed value in (a), we have:

C = 2

Using the assumed values, the value of the cost to subordinate male is 2

<h3>The net benefit to subordinate male</h3>

The Krakauer's formula for this is:

Net Benefit = rB - C

Given that r = 0.42, the equation becomes

Net Benefit = 0.42 * 5 - 2

Evaluate

Net Benefit = 0.1

Using the assumed values, the value of the cost to net benefit to subordinate male is 0.1
