Following the fusion of an egg cell and sperm cell, the resulting diploid cell divides by mitosis to create two new daughter cells. Each daughter cell contains pairs of chromosomes, with one set inherited from each parent.
Which of the following best describes the pairs of chromosomes that are present in each newly formed daughter cell?
Choose 1 answer:
A) The pairs are homologous chromosomes that have the same set of genes, but likely different variations of those genes.
B) The pairs are non-homologous chromosomes that contain different sets of genes.
C) The pairs are homologous chromosomes that have identical copies of every gene.
Answer: A
i have no idea why
The pairs are homologous chromosomes that have the same set of genes, but likely different variations of those genes. The correct option is A.
What are homologous chromosomes?Among a pair of chromosomes with the very same gene sequence, loci, chromosomal size, and centromere location is referred to as a homologous chromosome.
One paternal and one maternal chromosome make up a homologous pair. In humans, the nucleus of a somatic cell contains 46 chromosomes.
Homologous chromosomes differ from sister chromatids because they are not identical and do not emanates from the same organism.
Sister chromatids are identical, side-by-side duplicates of each other that form as a result of DNA replication.
Homologous chromosomes do not pair together during mitosis. Homologous chromosomes line up end-to-end in mitosis so that when the cells divide, each daughter cell receives a sister chromatid from both members of the homologous pair.
Thus, the correct option is A.

What are some examples of non-native species that have been Introduced to and thrive in Los Angeles increasing the overall "biodiversity" because of human activity?
The House Sparrow was introduced to North America from Europe. It is not really a sparrow but a European weaver-finch. It is highly successful, tends to follow human habitation, thrives in agricultural areas, and does not damage the local ecosystem. I would rate it a neutral. Bird of the Day: A Sparrow that's not a Sparrow, and a Successful Immigrant
The reintroduction of wolves into Yellowstone has had a positive effect on the ecosystem there. Wolf Reintroduction Changes Ecosystem
Horses were also introduced from Europe to North America and seem to have been neutral toward the ecosystem (unless you are a cattle rancher). They could be considered a reintroduction since they did evolve in North America also but just died out in the past.
Wild turkeys were introduced to the Western states from its native location in the Eastern US. They have been successful and effect on the ecosystem seems at worst neutral.
Two introductions that we regard as very beneficial animals, the earthworm and the European honeybee had negative effects on the native North American ecosystem, but very positive effects on those plants that the settling Europeans were trying to grow. The earthworm had been killed off the ice age in the Northeast and was introduced via the ballast from ships. Earthworms ground through leaf litter that the trees depended on and resulted in sparser forests. Honeybees were deliberate introductions. The native bees were few and favored only a few plants. The European honeybee was enormously fertile and liked pretty much all flowering plants making it a major league pollinator.

Explanation:
A normal process through which cells mature. This process of specialization for the cell comes at the expense of its breadth of potential.

In wolves, gray coat color (G) is dominant to black (g) and brown eyes (B) are dominant to blue (b). The genes that control these traits are located on different chromosomes. The alpha male of the pack has the dominant phenotype for both traits and is heterozygous for both traits. The alpha female has brown eyes and a black coat; she is heterozygous for eye color. Which option represents gametes that would be made by the alpha female
The combination of gametes that will be produced by the Alpha female is Bg, Bg, bg and bg.
According to this question, two genes coding for eye color and coat color in wolves are involved. Gray coat color (G) is dominant to black coat color (g) while brown eyes (B) are dominant to blue eyes (b). The alpha female of the pack is said to have a brown eyes and a black coat (gg) but she is heterozygous for eye color (Bb). This means that she posseses the following genotype: Bbgg. According to Mendel in his law of independent assortment, alleles of a gene will segregate into gametes independently of one another. This means that the alpha female with genotype (Bbgg) will segregate into the following combinations of gametes: Bg, Bg, bg and bg.Learn more about gamete formation at: https://brainly.com/question/11523490?referrer=searchResults
