Answer:

In biological system, cell is known as the basic unit of all organisms. Unicellular organism consist of one cell only but that single cell helps them to perform all the functional activity.

Levels of organization in biological systems is defined as the hierarchy of several components from smallest to complex in biological system.

Cell is one of the important part of Levels of organization in biological systems, as in multicellular organisms group of cells form tissue that create an organ and many organs together form organ system within an organism. The cell is basic unit in all organisms and without a cell, an organism can not develop.

The group of these organism formed from a small cell then form complex component of Levels of organization such as population, community, ecosystem and Biosphere (in sequential order).

If the parent genotypes are Aa and Aa, the offspring are expected to be _____. 1/2 AA and 1/2 aa all Aa 1/4 AA, 1/2 Aa, 1/4 aa 3

Punnet squares are your friend with these kinds of questions :)

 A | a |
A | AA | Aa |
a | Aa | aa |

Now we can easily see that 1/4 of the offspring will be AA, 1/2 will be Aa, and 1/4 will be aa. Therefore, it is the third answer that's correct (1/4 AA, 1/2 Aa, 1/4 aa). Hope this helps! :)

A genetic locus has two alleles. One has a frequency of 0.12; the other has a frequency of _______.

saw5 [17]

Answer:

Option A

Explanation:

As per the first equation of equilibrium of Hardy Weinberg, the sum of frequencies of alleles at the locus is equal to unity.

Thus,

If "p" represents the frequency of dominant allele, "q" represents the frequency of recessive allele and at equilibrium

$p + q = 1\\$
