<h3>Answer:</h3>

B) Variations that decrease reproductive success are more likely to be passed on.

<h3>Explanation:</h3>

Reproductive success (RS) of people in a society is the generation of the unconventional family per breeding effort or lifetime (LRS). LRS preferences need not speculate the health of a genotype. Longitudinal thoughts of LRS are superior to cross-sectional thoughts. Usually, a small symmetry of people produces the following generation.

<h2>Operational definition</h2>

Explanation:

An operational definition is used to define the terms of a process which is needed to determine the nature of an item such or its properties such as quantity, chemical composition, etc.
The degree of operationalization vary.

Operational definitions can be defined as labels and concepts in the way they are measured.

For example: The operational definition of weight can be like this:

How many pennies are needed to balance the weight of something.

When we hang something from a spring, how much a spring streches.

Answer: 16 different gametes

ABCd
ABcD

AbCD

aBCD
aBCd
aBcD
aBcd
abCD
abCd
abcD
abcd

Explanation:

Gamete formation involves the random and independent segregation of alleles. During anaphase 1 (meiosis), occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair.

The number of gametes with different combinations is 2ⁿ, where

n = number of homologous pairs.

In the exposed example there are 4 pairs of chromosomes, so

the number of possible combinations of chromosomes = 2ⁿ = 2⁴ = 16

Individual: AaBbCcDdEe

You can make use of the fork line method to easily figure out the possible gametes.
