Summary Introduction

Introduction: A gene can be referred to as a part of genetic material. They pass information from one generation to another. The genes contain DNA which decides the genotype of an individual. The genotype along with the geographical conditions determines the phenotype of an individual. The phenotype can be described as the physical appearance of an individual.

Answer to Problem 1TYU

Correct answer: Gene pool represents the genetic information of a population. Hence, the correct answer is option (b).

Explanation of Solution

Reason for the correct answer:

Gene pool of a population gives information about all the alleles for all the loci present in that population. It provides information about the genotypic description of the population by which phenotypic description of that population can be determined. The genetic variation among different populations can also be identified with the help of a gene pool. Therefore, gene pool gives the genetic description of a population.

Option (b) is given as “gene pool”.

Gene pool gives the information about all the alleles of all the loci in a population which represents the genetic description of a population. Hence, option (b) is correct.

Reasons for incorrect answers:

Option (a) is given as “phenotype”.

The phenotype of a population gives the information about the physical appearance of the individuals living in that population which does not represent the genetic description a population. Hence, option (a) is incorrect.

Option (c) is given as “genetic drift”.

Genetic drift can be described as a random change in the frequency of allele of a small population which does not represent the genetic description of the population. Hence, option (c) is incorrect.

Option (d) is given as “founder effect”.

The founder effect is also a genetic drift which occurs when a new area is colonized by a small population. Hence, option (d) is incorrect.

Option (e) is given as “changes in allele frequency”.

The change in allele frequency describes only about the genetic variation within the population, but do not give all the genetic description of a population. Hence, option (e) is incorrect.

Hence, options (a), (c), (d), and (e) are incorrect.

Conclusion

Gene pool represents the genetic description of a population.

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.)   Data Table 1Stage    Totals    PercentInterphase        Mitosis:        Prophase        Metaphase        Anaphase        Telophase        Cytokinesis        Totals    100    100% To find the length of time whitefish blastula cells spend in each stage, multiply the percent (recorded as a decimal, in other words take the percent number and divide by 100) by 24 hours.
