Answer:
The genotypes found in the F2 offspring will be An1An1, An1An2 and An2An2.
Explanation:
In the example given in the question, the color of the petals of snapdragon flowers are given with the An1 allele having full activity and the An2 allele being the null allele. For the F1 offspring, two snapdragon flowers are crossed, one with red petals which is An1An1 and one with ivory petals which is An2An2. All the genotypes for the F1 offspring will result in An1An2.
Then using this F1 offspring, the F2 offspring is found and the genotype of the F2 offspring will be An1An1 / An1An2 / An1An2 / An2An2.
So the genotypes found in the F2 offspring will be An1An1, An1An2 and An2An2. One red petal snapdragon, 1 ivory snapdragon and 2 pink snapdragons.
I hope this answer helps.

The right thing to do would be to plan housing and business developments that are within walking distance of businesses and parks.
<h3>Effects of urbanization</h3>
Urbanization often requires the removal of forests for construction. Urban areas are usually also characterized by a copious number of vehicles on the road
These impact the environment negatively through pollution.
When housings are planned such that they are at trekkable distances to businesses, there would be fewer vehicles on the road and the impact on the environment will reduce accordingly.

Physical resources that are extracted from the ocean and are useful to humans include petroleum and natural gas.
<h3>What are physical resources?</h3>
- Physical resources are tangible items such as raw materials which are required by the humans for their need.
- Water, air, soil, rocks are all physical resources of the terrestrial and aquatic ecosystems.
- Land, water and air are necessary for our survival.
- Geological features like volcanoes, caves and fossils are also a part of physical resources.
- The dead and decaying remains of plants and animals over thousands of years in the oceans (marine system) form petroleum and natural gas which are used as fuels to power vehicles.
- Coal is obtained from the remains of plants over hundreds of millions of years ago in terrestrial ecosystem.
- Petroleum and natural gas are non renewable so we must use them judiciously.
