- In a natural population it was noticed that some natural variants with different forms, behaviors or physical traits are better at getting through life and reproducing compared to other others. Look at the diagram below, decide which choice best explains why the natural occurring trait is passed on. 1 2 RRORS O Brown fur color in mice blends in with the environment better so the brown mice will survive and pass on their fur color traits O White fur color in mice blends in with the environment better so the white mice will survive and pass on their fur color traits O Both brown and white fur color in mice blend in with the environment well so both types of mice will survive and pass on their fur color traitsWhich of the following statements about Hardy-Weinberg graphs is false? Group of answer choices The x-axis is always the dominant allelic frequency. The y-axis is the genotypic frequency. The maximum heterozygous genotypic frequency is where the dominant and recessive allelic frequencies intersect. As the dominant allelic frequency increases, the recessive genotypic frequency decreases.Which of the following statements about the theories of senescence is correct? Question 2 options: The reason why organisms become old and decrepit is because an individual would often have accumulated too much energy in its lifetime in the form of fat reserve; therefore, an older individual often dies from old-age related diseases. An allele that shows its deleterious effect later in life will always have a smaller impact on an organism's fitness than an allele that shows its deleterious effect early in life. Therefore, late-acting deleterious mutations can be fixed in the population, resulting in shortened lifespans. The allele that can result in early reproduction will always be selected for, even if it comes with a cost of earlier senescence. Typically, for species that live fast would usually die young. None of the above

The ability to taste the horridbitterness of PTC present in grapefruit respectively human brain tissue is due to a dominant alial. A small tribe of 637 Papa New Guinea hens was tested by a population geneticists the following results were displayed. Tasters Non-tasters Total Males 171 86 257 Females 337 43 380 Total 508 129 637 A.)Calculate the recessive ally of frequency (i)among males (ii) among females B.) calculate the amount of individuals being homeless sigus for tasting PTC, also the number of heterozygotes individuals and non tasters within the tribe.

- A large population of moths contains 35% white moths caused by the double recessive genotype, bb.What are all the allelic and genotypic frequencies for this population?Frequency of thedominant alleleFrequency of therecessive allele% homozygous dominant% homozygous recessive% heterozygousThis lab exercise requires that we count certain Mendelian traits among students present in the lab. Your professor will explain each trait being addressed and will then ask students to identify if they are dominant or recessive for that specific trait. The collected traits will then be plugged into the Hardy-Weinberg Equilibrium formula in order to calculate frequency of Homozygous dominant, Heterozygous and Homozygous recessive individuals in the same. p2 + 2pq + q2 = 100 given data: trait: hair swirl 19 individuals total. 10 had the homozygous dominant hair swirl trait: clockwise the nine other were recessive please do a step by step explanation with the calculation using this data, as I am very unfamiliar with what values mean what and the equation itself thank you!The biological selection of a particular allele for a trait to be passed to offspring has nothing do with the selection of the allele for another trait. Which of the following supports this statement? O law of independent assortment O law of dominance O law of segregation O law of recessiveness
- one specific example of each type of sexual selection can I have an example in a list for each type of sexual selection intersexual and intrasexualI asked this question before but the solution was not correct and I'm really trying to figure out how to do this to get the correct answer. Please show work!DNA typing is used to compare evidence DNA (E) left at a crime scene to two suspects(S1 and S2). Suspect 1 is excluded by the evidence, but suspect 2 remains included. What isthe frequency of suspect 2's genotype if the allelic frequencies in the population are f(A1) =0.1, f(A2) = 0.2, and f(A3) = 0.7, and the population is at Hardy–Weinberg equilibrium?The answer is 0.49.Which of these statements would be consistent with the changes we see in the frequency of the recessive allele? Natural selection has been favoring those individuals who are heterozygous alleles. Natural selection has been favoring those individuals who are homozygous for the hemoglobin S allele.
