Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

A population of mice is at HardyWeinberg equilibrium at a gene locus that controls fur color. The locus has two alleles, M and m. A genetic analysis of one population reveals that 60% of its gametes carry the M allele. What percentage of mice contains both the M and m alleles? a. 60% b. 48% c. 40% d. 36% e. 16%
1. For a particular rodent, black fur (B) is dominant over brown fur (b), and a long tail (L) is dominant over a short tail (l). Create a Punnett square that shows the genotypes of all the possible offspring that could result from the breeding of 2 rodents that are both heterozygous for both traits. Include the percentage/ratio of occurrence for each phenotype.
1.) Consider flower color in a hypothetical population of 7,000 flowers, red flowers (4,000), blueflowers (2,000) are dominant over pink flowers. If there are 1,000 pink flowers, find thefollowing:a. Frequency of dominant (red flower) alleleb. Frequency of recessive (pink flower) allelec. Frequency of each genotype (homozygous dominant, homozygous recessive,heterozygous)d. Make a Punnett square and use the rule of multiplication.
1. What are the expected proportions in the offspring? You will need to propose which trait is dominant, either the wild-type or the mutant? 2. Using the chi square calculator to analyze your results. Provide a summary that includes whether you support or reject the hypothesis.
1.)The frequency of the R allele for round seeds in a certain population of 500 peas wasfound to be 0.45. How many of them were wrinkled? How many of them had the rr genotype? How many of them were round? 2.)In humans, a dominant allele controls the formation of a cleft chin, a Y-shaped fissurein the chin caused by an atypical bone formation in the mandible (this phenotypeis also known as a chin dimple). A survey of 1200 college students found that108 of them did not have a cleft chin. What was the frequency of heterozygotes inthat student population?
A wild population of pea plants has two alleles for flower color in its gene pool. A dominant allele (P) specifies purple flowers; a recessive allele (p) specifies white flowers. If the die frequency of allele P is 0.75, what is the expected frequency of allele p?
Several alleles affect traits of roses, such as plant form and bud shape. Alleles of one gene govern whether a plant will be a climber (dominant) or shrubby (recessive). All F1 offspring from a cross between a true-breeding climber and a shrubby plant are climbers. If an F1 plant is crossed with a shrubby plant, about 50 percent of the offspring will be shrubby; 50 percent will be climbers. Using symbols A and a for the dominant and recessive alleles, make a Punnett- square diagram of the expected genotypes and phenotypes the cross between the F1 offspring and the shrubby plant.
Give an example of a trait that may have evolved as a result of the handicap principle and explain your reasoning.
In peas, the allele Le produces tall plants and the allele le produces dwarf plants. The Le allele is dominant to le. If a tall plant is crossed with a dwarf, the offspring are distributed about equally between tall and dwarf plants. What are the genotypes of the parents?
1. Given that there's a science to back you up and you actually have the capability of producing an offspring with your desired traits, would you do it? What should the limitations be if you have to put a limit on this? 2. On the other hand, give some reasons why you will not choose to do it even if there's a science to back you up and you actually have the capability of producing an offspring with your desired traits.
6. In a population of mice, coat color is controlled by a single additive locus. BB mice are black, bb mice are white, and Bb mice are grey. The population is currently in HWE, with 1% of the mice having the white phenotype. Grey mice have twice as many offspring as black or white mice. What will be the frequency of the b allele in the next generation? The answer is supposed to be 0.16, can you explain how to get to this?
5. The horned / hornless traits in sheep are examples of sex-influenced traits. Horned (H) acts as a dominant in rams, while hornless (H’) acts as a dominant in ewes. Thus, the heterozygote exhibits a different phenotype depending upon the sex of the individual. Give the phenotypic results expected in the mating of heterozygous hornless ewes with heterozygous horned rams. Don't use open ai
