Job specialization can most likely result in _____.
Snezhnost [94]

Answer:

Employee boredom

Explanation:

When an employee specializes in a specific part of job, and it tends to be repetitive each day, it leads to Employee boredom . Therefore, there should always be novel challenges and tasks in work place which do not make an employee feel boring about same monotonous work each day in which they are already specialized.

This never intends to mean that Job specialization is a bad thing, but there should be versatility in work because the work of repetitive nature tends to create a sense of boredom in person and makes his mind less creative as he is doing something daily on which he is expert and do not needs more learning.

Hope it helps!

If an organism is homozygous for a particular trait, the organism A. has extra alleles on both chromosomes in a chromosome pair.
inysia [295]

<em>B. Has the same allele on both chromosomes in a chromosome pair. </em>

<u>Here is why:</u>

Homozygous means the same, while heterozygous means different. If both of the same alleles are on both chromosomes, then it will be a homozygous.

There can be two types of homozygous alleles.

~

<em>Homozygous Dominant</em>: BB

<em>Homozygous Recessive</em>: bb

<u>Notice in both of these they were the same alleles.</u>

~

<em>Heterozygous</em>: Bb

<u>Notice how both are different alleles.</u>

~

Below I have attached a diagram of a Punnett square I have made.

On the left is a homozygous recessive allele pair.

On the top is a heterozygous allele pair.
