if there were no suppression of dna replication between meiotic divisions but cytokinesis proceeded normally, what is the most likely outcome of meiosis?

Answers

Answer 1
Answer: The answer is 4 diploid cells.

Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces two haploid cells. Meiosis II is analogous to mitosis, so in total, meiosis results in four haploid cells. This is achieved through suppression of DNA replication between two meiotic divisions.
If there were no suppression of DNA replication, then meiosis I would produce two diploid cells, and after meiosis II there will be four diploid cells.

Dr. Wilson is analyzing the similarities between the wing of a bat and the arm of a monkey. He is using _____.

Answers

The correct answer for the question that is being presented above is this one: "comparative morphology." Dr. Wilson is analyzing the similarities between the wing of a bat and the arm of a monkey. He is using comparative morphology. Comparative morphology refers to the analysis of the patterns of the locus of structures within the body plan of an organism, and forms the basis of taxonomical categorization.

B) comparative morphology is correct

Over years of selective breeding, French bulldogs have developed extremely short snouts and flat faces. These traits, although attractive to the dog owners, can make it difficult for the dogs to breathe.Which of the following processes led to the presence of these traits?(Choice A)
A
Artificial selection

(Choice B)
B
Natural selection

(Choice C)
C
Environmental selection

(Choice D)
D
Sexual selection

Answers

Choice A, artificial selection, led to the presence of these traits in French bulldogs.

What is Artificial selection?

Artificial selection, also known as selective breeding, is the process of breeding organisms with desirable traits in order to produce offspring with those traits. In the case of French bulldogs, humans selectively bred dogs with shorter snouts and flatter faces in order to create a breed that was aesthetically pleasing. However, these traits also led to health problems such as difficulty breathing.

Natural selection, on the other hand, is the process by which organisms with advantageous traits are more likely to survive and reproduce, leading to the evolution of those traits in a population.

Environmental selection refers to the process by which the environment favors certain traits over others. Sexual selection is a type of natural selection that occurs when individuals with certain traits are more likely to attract mates and reproduce.

In the case of French bulldogs, these traits were not naturally selected for based on survival advantages, nor were they the result of environmental or sexual selection. Rather, they were artificially selected for by humans, leading to unintended consequences for the dogs' health.

Answer:

Artificial selection

Explanation:

The Pennsylvania Dutch Amish have historically been a small, isolated population in the United States. Within this population, there is a different frequency of alleles than there is throughout the population of southern Germany and Switzerland from which they came. Given this information, how is it possible that polydactyly, or the condition where people have extra fingers and toes, is more common within this group? Please choose the correct answer from the following choices, and then select the submit answer button.

Answers

Answer:

Polydactyly is a genetic condition where formation of extra finger or toe takes place.The extra finger or toe is called as supernumerary.

Explanation:

Polydactyly is associated with mutation in genes in their cis position Mutation in Hoxa gene also results in polydactyly.

It is associated with autosomal dominant mutation that occur in single gene.

This condition appears 1 in every 500.This is a common disorder in African black children and is more frequently found in Africans that are living in Eastern and central part.

Polydactyly is mainly affects the right toe or finger.

It is common in men.

The extra digit may be functional or not,partly formed with some bone.
