In wheat plants, the feature of having colored kernels is dominant to having white kernels that lack pigment. A true-breeding pl
Lynna [10]

Answer: It occurred a dihybrid cross and epistasis.

Explanation: In dihybrid cross, two different genes controlled two different traits. When they interact with each other is called Epistasis. However, in wheat plants, the genes related to color kernels don't act opposedly to each other. In other words, the genes have the same role in producing protein, so they can substitute for each other.

In the color determination mechanism, a biochemical reaction is necessary to convert a precursor substance into a pigment and that reaction happens with the product of either genes. That's why having a dominant allele makes the wheat colorful. So, crossing colored kernels with white ones will produce a heterozygous F1 generation. Crossing this generation will produce a F2 generation with modified ratio of 15 colored: 1 non colored because, every individual who has  dominant alleles will produce the substance and thus the biochemical reaction will happen. Only recessive homozygous ones won't have the substance and so won't have color.

Explain why dead or cliseased trees can serve as a food source for some<br> birds.
lianna [129]

Answer:

Dead or diseased trees can serve as a food source for some birds because there are some insects which feed on these dead trees and these insects are eaten by some birds. The body of insects is made of protein so it is a good food for birds. The insects which lived in the dead and diseased trees and feed on it are termites and bugs. Termites are also known as white ants. They feed on dead bodies of plants.

Otrada [13]

Answer:

Recombinant DNA can replace a gene in an animal’s genome.

Explanation:

The molecular cloning process involves in creating Recombinant DNA. This DNA is used to replace or replicate any specific gene. This is done by the process of PCR to replicate it directly.

This formation is done in the presence of a vector. This method is used in the field of veterinary office, pharmacy and many more.  It has the ability to replace the gene of an animal’s genome.
