Read the passage. Then explain the ways humans have influenced the traits in corn plants and the impacts each biotechnology has had.

Passage
Many of the types of corn found in grocery stores were originally bred for their taste and productivity. But these varieties are often threatened by pests. This makes it harder for farmers to produce enough corn.
Scientists have used genetic engineering to make GMO corn plants that are resistant to pests. In one type of GMO plant, they added genes from bacteria that live in soil. The genes let the GMO plants produce a bacterial protein that kills certain insects.

Answers

Answer:

It decreases cost of production on the crop as well as increase production.

Explanation:

It is a very efficient method to save a corn plant from the attack of bacteria. This method is used in almost each and every plant in order to make it resistance against harmful pests and microorganism. By using this technology, the cost of production on the growing of crop decreases which gives more profit to the farmers as well increase the overall productivity of that corn crop.

Answer:

One of the ways we have influenced the traits in corn is through selective breeding. We now have taller plants, and bigger ears of corn, that taste better. Another way we have influenced the traits is by modifying them to be pest resistant.

The botanist wanted to produce a generation of snapdragons that all had pink flowers.

State the phenotypes of the parent plants that the botanist would need to cross.
Explain your answer.​

Answers

Answer:

He would need to cross one homzygous red (RR) and homzygous white (rr)

Explanation:

Flower color in snapdragons is controlled by a gene whose alleles exhibits incomplete dominance. The allele for red coloration (R) is incompletely dominant over the allele for white coloration (r). The intermediate phenotype that is produced in an heterozygous state (Rr) is PINK.

According to this question, a botanist wanted to produce a generation of snapdragons that all had pink flowers (Rr). This means that in order to do this, the botanist would need to cross a red snapdragon plant (RR) and a white snapdragon plant (rr) to produce an 100% Pink (Rr) snapdragon in the F1 generation.
