it is true that to test the smell of a substance, partially fill your lungs with air and, while standing slightly back from the fumes, use your hand to waft the odors gently toward your nose.

<h3>What is the odor?</h3>

An odor basically caused by one or more volatilized chemical compounds, which are generally found in low concentrations and can be detected by humans and animals using their sense of smell.

An odor is also known as a "smell" or a "scent," and it can be either pleasant or unpleasant.

To test the aroma of an actual content, temporarily fill the lungs with air and, standing gently downward from the fumes, gently billow the odors toward the nasal passages with the hand.

Thus, the given statement is true.

Anestetic [448]
Crossing two true breeding parents with opposite parents is the key:

Assume W is straight wing and w is curly.
Then you are crossing WW with ww
This will result in ALL Ww as offspring - so all straight offspring

If you then cross Ww x Ww you end up with a mix of 
WW (1), Ww (2) and ww (1) - so a mix of straight and curly

Answer: 
P generation has straight wings and curly wings
F1 has all straight wings
F2 has straight wings and curly wings

In sheep, white vs yellow body fat is determined by a single pair of autosomal alleles. In a large, randomly mating flock, 23 pe
Drupady [299]

Answer:

Option A , The allele for yellow is dominant to white

Explanation:

It is given that 23 percent of the sheep have white fat and 77 percent have yellow fat.

Thus, it is clear that sheeps with yellow fat is a dominant characteristics.

Usually, the frequency of homozygous recessive allele in a given population is represented by  q^2

and here q^2 = 0.23

Frequency of allele for white fat = q = \sqrt{0.23} \\q= 0.479

While frequency of homozygous dominant allele and heterozygous dominant allele is represented by p^2+2pq\\

And here p^2+2pq = 0.77

Allele for yellow fat = 1-q\\= 1-0.479\\= 0.521

Hence, option A is correct.
