Flower color in snapdragons results from the amount of the pigment anthocyanin in the petals. Red flowers are produced by plants
USPshnik [31]

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.

In capturing essential resources, humans often modify their environments. Have you seen any examples of landscapes radically tra
Rina8888 [55]

Answer:

Humans have destroyed and modified various locations, such as forests, jungles, oceans. They begin to modify an environment in order to build new infrastructures, like buildings, factories, or even communities.

Explanation:

The reason for this is because they want to get as much resources for economic purposes, like for example mines, touristic places, factories. At first, this interaction affects the environment more, because of the loss of species or resources due to the human activity. Then, after this, it will affect the human, because of the lack of resources and global contamination caused by the environment being destroyed or modified.
