Answer: Codominance.

Explanation:

Codominance is a relationship between two parts of a gene. Offspring get one part of a gene, known as an allele from each parent. When the alleles are different, a dominant allele is usually expressed and the effect of the allele is usually covered or masked which is recessive. However, when Codominance occurs, neither of the alleles is recessive and phenotypes of both alleles are expressed.

In the above case, mating the yellow and white corn by the farmer resulted in offsprings that have nearly an even mix of both white and yellow corn. This is known as Codominance because no allele appeared to be recessive. The phenotype of both the alleles for yellow and white corn are expressed in the offsprings.

A mistake happens during mitosis g where all of the mitochondria are pulled to one pole of the cell and none are pulled to the o
LuckyWell [14K]

Answer: Daughter cell that does not receive mitochondria, will not be able to produce the energy needed to carry out cell functions. The cell that receives all the mitochondria, will be able to carry out cellular respiration and thus produce energy.

Explanation:

The mitochondrion is a cellular organelle found in eukaryotic cells, and provides the energy needed to carry out cellular activity. They are characterized by their large size, compared to other cell organelles, and their globular shape. <u>Mitochondria generate most of the chemical energy needed to activate the biochemical reactions in the cell</u>,<u> through a process called cellular respiration</u>. It irefers to a set of biochemical reactions by which certain organic compounds are degraded by oxidation into inorganic substances. The chemical energy produced by mitochondria is stored in an energized molecule called adenosine triphosphate (ATP).

Then, if during cell division, one of the daughter cells does not receive mitochondria, it will not have the necessary organelles to carry out cell respiration and will not be able to produce the energy needed to carry out cell functions. The cell that receives all the mitochondria will have no major problems, it will be able to carry out cellular respiration and thus produce energy.

o-na [289]

Answer:

A) It uses less energy to make something from recycled materials than from new materials.

Explanation:

When a recycled material is used to make a new product, it conserves energy because the recycled materials have already been processed once; so making something from it for the second time uses less energy-intensive than the first. For example: Making new aluminium from old products uses 95% less energy than making it from scratch.

Hence, the correct answer is "A)"

Is dog breeding an art???
Law Incorporation [45]

Answer:Just because two dogs complement each other in physical appearance does not mean they will complement each other when comparing pedigrees. As spoken so well by my mentor, breeding is an art. When doing a breeding, stick to the breed standard, and strive for perfection

Two heterozygous dominant parents for attached earlobes are crossed to predict the traits of their offspring. What is the ratio
photoshop1234 [79]

Answer:

A - 3:1

Explanation:

In order to determine what number of offspring will have attached earlobes, we must make a Punnett table. We know that attached earlobes are the dominant gene, and we know unattached earlobes are recessive.

| P | p

——————-

P | PP | Pp |

——————-

p | Pp | pp |

As we can see, only one out of the four squares has two recessive genes. Therefore, our answer would be A - 3:1.
