The answer is C) 9:3:3:1
This looks like a dihybrid cross where the expected phenotypic ratio is 9:3:3:1. However, in nature, the numbers cannot be absolut. Let's check it out:
242 purple wrinkled
84 purple smooth
70 yellow wrinkled
24 yellow smooth
Divide all by the smallest number:
242 purple wrinkled / 24
84 purple smooth / 24
70 yellow wrinkled / 24
24 yellow smooth / 24
We have
10.1 purple wrinkled which is near to 9
3.5 purple smooth which is near to 3
2.9 yellow wrinkled which is near to 3
1 yellow smooth
The seed offers the embryo protection, nourishment, and a mechanism to maintain dormancy for tens or even thousands of years, ensuring germination can occur when growth conditions are optimal. Seeds therefore allow plants to disperse the next generation through both space and time.

The following describe the relation of smoking with lung cancer
- Cancer is caused by oncogenes activating substances [OAS] some of them causes mutation in the body
- These oncogenic substances in the smoke produced while smoking contains nicotine, hydrocarbons, cyclohydrocarbons and various other factors which converts normal cells into cancerous cells
- Hence,
- smoking
- causes
- oral
- and
- lung
- cancer
