The ozone layer protects life on Earth by absorbing harmful ultraviolet radiation. The ozone layer is located between 17 kilomet
Zolol [24]
The correct answer is (2) - Stratosphere. Ozone is found in the stratosphere , a layer beginning between 6 and 10 miles above the earth's surface and extends upward to about 30 mile above the surface of he earth. The ozone that is found in the stratosphere absorbs most of he harmful ultraviolet sunlight and is thus called the "good ozone" Ozone is also found in the lower region of the atmosphere known as the troposphere. But the ozone here strongly reacts with molecules causing toxicity in plants. The ozone is therefore termed as "bad ozone."

timofeeve [1]

Answer:

1 DDRR - Red, non-dexter

2 DDRr - Roan, non-dexter

2 DdRR - Red, dexter

4 DdRr - Roan, dexter

1 DDrr - white, non-dexter

2 Ddrr - white, dexter

Explanation:

Dexter is deleterious in homozygous condition, hence, phenotypes are heterozygous.

Roan are also heterozygous.

If dexter allele is represented by D, non dexter individuals will be DD dexter individuals will have the genotype Dd.

If colour in cattle is represented by R, red individuals will be RR, white will be rr, then roan colour will be Rr.

Hence, roan dexter cow and roan dexter bull will both have DdRr genotypes.

Crossing the two:    DdRr   x   DdRr

Progeny:

1 DDRR - Red, non-dexter

2 DDRr - Roan, non-dexter

2 DdRR - Red, dexter

4 DdRr - Roan, dexter

1 DDrr - white, non-dexter

2 Ddrr - white, dexter

<em>Others that are either aborted or stillbirths include:</em>

<em>1 ddRR </em>

<em>2 ddRr </em>

<em>1 ddrr</em>
