The following phenotypic classes reflect offspring that were generated as a result of a crossover event
- miniature wings
- garnet eyes
Explanation:
When the miniature wings and garnet eyes links up with the 8 map unit that are present between them. After that the presence of two recombinant classes must complement together and make 8% of total i.e. they contribute 4% each. together the parental classes make up to 92% by contributing 46% one.
This can be understood through a phenotypic ratio calculation, which can be expected from it.
wild type: 4% x 800 = 32
miniature wings: 46% x 800 = 368
garnet eyes: 46% x 800 = 368
miniature wings, garnet eyes: 4% x 800 = 368
Answer:
The cell is in a hypertonic solution.
Explanation:
The solution is hypertonic because the amount of solute(s) is higher outside of the cell than it is inside the cell, so the solvent (e.g. water) would move from the cell to the solution in order to obtain equilibrium between the two.
Contraction is the answer
Answer: It shows the distribution of the population with respect to a characteristic, quantitative and continuous, such as the weight or height of a population. It is used to determine the degree of homogeneity of the values studied, or to see the degree of variability, and therefore, the dispersion of all the values taken by the parts.
Explanation:
A histogram is a graphical representation of a variable using bars. In such a bar, <u>its area is proportional to the frequency of the values represented</u>. Thus, it shows the distribution of the population, or of the sample, with respect to a characteristic, quantitative and continuous, such as the weight or height of a population. It is used to determine the degree of homogeneity of the values studied, or to see the degree of variability, and therefore, the dispersion of all the values taken by the parts.
In order to construct a histogram first we need to have a frequency table with all the information. On the abscissa axis (horizontal axis) the intervals are placed from smallest to largest. On the ordinate axis (vertical axis), the absolute frequencies of each of the intervals are represented. Then, the rectangular bars of equal width are drawn, and the height represents the absolute frequency. All bars touch the bars next to each other, unless an interval has zero frequency (the height of the bar will also be zero).
<u>Thus, histograms are used to describe populations since they represent a variable and in what proportion of the population it is found.</u>
Complete question:
Thinking creatively about evolutionary mechanisms, identify at least
two schemes that could generate allelic polymorphism in a population except natural selection that favors heterozygotes.
<u>Select the two correct answers.</u>
-inbreeding among individuals in the population
-purifying selection against mutational variants of alleles in the population
-continuous migration of individuals with new alleles into the population
-mutations that do not severely affect viability and reproductivity
-genetic drift of alleles common in the population
-events leading to genetic bottleneck effect
Answer:
The two events that might favor heterozygotes among the options are
- The Continuous migration of individuals with new alleles into the population
- Mutations that do not severely affect viability and reproductivity. These might favor heterozygous frequencies.
