Reproductive system infection

The biological process through which parents produce new children is called reproduction. A reproductive system is a group of internal and external organs that collaborate to allow males and females to reproduce. Many experts believe that the reproductive system is one of the most important systems in the body due to its crucial function in the survival of the species. Among the body's basic systems, the reproductive tract is the one that differs the most between sexes, and it is also the only one that does not operate until puberty.

1. How can negative traits that don't show up until old age continue in populations?
(Why aren't they eliminated through natural selection?) As part of your answer, provide
an example.
2. Imagine a population of mice living in a grey, rocky environment. Some mice are grey
and some are brown. If natural selection occurs in this population, what would you
expect to see if you returned in 100 mouse generations? Describe what you'd see in
terms of fur colors in the population.
3. Imagine a population of mice living in a grey, rocky environment. Some mice arelgrey
and some are brown. If mutations occur in this population, what could you see if you
returned in 100 mouse generations, that would tell you mutations had occurred?
Describe what you'd see in terms of fur colors in the population, and how it would be
different from what you'd see in #2.
4. If dark skin helps protect folate and that's so important for fetal development, why
didn't all humans evolve to have dark skin? Why did humans living in the north and
south evolve lighter skin? Use knowledge from the evolution lab to answer.

In a population of lizards, color is genetically determined. The current population has two two phenotypes: blue and yellow. Which of the following scenarios could result in evolution by migration? O A disease indiscriminately reduces the population by 90%. Birds are better able to see and therefor prey on blue lizards The population is joined by individuals from a nearby population that has an allele for a red phenotype. Females preferentially mate with individuals exhibiting the blue phenotype.
Which of the following is not true of natural selection? (a) natural selection acts to preserve favorable traits and eliminate unfavorable traits (b) the offspring of individuals that are better adapted to the environment will make up a larger proportion of the next generation (c) natural selection directs the course of evolution by preserving the traits acquired during an individuals lifetime (d) natural selection acts on a populations genetic variability, which arises through mutation (e) natural selection may result in changes in allele frequencies in a population
The reason spontaneous mutations do not have an immediate effect on allele frequencies in a large population is that: a. mutations are random events, and mutations may be eitherbeneficial or harmful. b. mutations usually occur in males and have little effect oneggs. c. many mutations exert their effects after an organism hasstopped reproducing. d. mutations are so rare that mutated alleles are greatlyoutnumbered by nonmutated alleles. e. most mutations do not change the amino acid sequence of aprotein.
In a particular population of mice, certain individualsdisplay a phenotype called short tail, which is inherited as a dominant trait. Some individuals display arecessive trait called dilute, which affects coat color.Which of these traits would be easier to eliminatefrom the population by selective breeding? Why?
@ 2 W S Rehpogs are mythical creatures. They are small and not very smart. Rehpogs live on the ground in a flat, warm habitat. Their fur texture and color ranges from thick purple fur to thin pink fur, depending on allele distribution. The dominant fur allele (R) codes for thick purple fur. The recessive allele (r) codes for thin pink fur. REMEMBER: a phenotype (fur color) is the physical expression of a genotype (two- letter code for the alleles present in that individual). Each individual has two alleles for fur color: X RR genotype is homozygous dominant = Thick purple fur phenotype Rr genotype is heterozygous = Thick purple fur (because of the presence of one dominant allele) rr genotype is homozygous recessive = Thin pink fur (because of the absence of a dominant allele) For the purposes of this experiment, Rehpogs mate once per year and produce two offspring each year. Rehpogs are monogamous, faithful and fertile. # 3 e d C C $ 4 r f V % 5 t g Oll 6 b y h & 7 O 8 n JL u i j O L m…
Consider the first copy of an allele for insecticideresistance that arises by mutation in a populationof insects exposed to an insecticide. Is this mutation an adaptation? If, after some generations,we find that most of the population is resistant,is the resistance an adaptation? If we discovergenetic variation for insecticide resistance in apopulation that has had no experience of insecticides, is the variation an adaptation? If an insectpopulation is polymorphic for two alleles, eachof which confers resistance against one of twopesticides that are alternately applied, is thevariation an adaptation? Or is each of the tworesistance traits an adaptation?
Three basic predictions underlie genetic drift in populations: (1) As long as the population size is finite,some level of genetic drift will occur; thus, withoutnew mutations, all variation will drift either to fixationor to loss. (2) Drift happens faster in small populationsthan in large populations. (3) The probability that anallele is fixed (goes to a frequency of 1.0) is equal toits initial frequency (p) in the population, while itsprobability of loss from the population due to drift isequal to 1 − p. Given these three predictions:a. What is the allele frequency of a new autosomalmutation immediately after it occurs in a diploidpopulation of size N = 100,000?b. What is the allele frequency of a new autosomalmutation immediately after it occurs in a diploidpopulation of size N = 10?c. In which population does the new mutation have ahigher probability of going to fixation by chancewith genetic drift?

Most new mutations are detrimental, yet rare beneficial mutations canbe adaptive. With regard to the fate of new mutations, discuss whetheryou think it is more important for natural selection to select againstdetrimental alleles or to select in favor of beneficial ones.

1. 9. You are a genetiCıst studying a population of 100 barn swallows. You are particularly interested in one gene, and upon examining the alleles present, you find one allele is quite common, accounting for 80 of the alleles in this population. What is the frequency of this allele in the population? 4. 5. The ability to breathe fire in dragons is controlled by a single gene with two alleles. The fire-breathing allele (F) is dominant to the non-fire breathing allele (f). In a population of 600 dragons, 150 dragons are non-fire breathing (ff) and the rest can breathe fire (either FF or Ff) The population is in Hardy-Weinberg equilibrium. The frequency of the dominant allele (F) is represented by "p and the frequency of the recessive allele (f) is represented by "q". Recall the allele frequency is p+ q = 1 and the Hardy-Weinburg equation is p2 + 2pq + q2 = 1 (2 pts). What is the frequency of the recessive allele (f)? Hint: you can figure out the frequency of ff, which is equal to q2, but…
If vestigial traits are no longer useful to an organism, why don't they evolve out of the population? * Individuals with the trait have developed new ways to use them. Individuals that have the trait continue to survive and reproduce, and they pass on th genes for that trait to the next generation. Individuals that have the trait must have some sort of evolutionary advantage. The individuals that have the trait become less common over time.
