3) Do you have hair on your middle phalange? Partner A: Yes or No Mid-digital hair is a Dominant trait. Look at the middle segments of all of your fingers. Note the presence or absence of hair. For the purposes of this exercise, if you have any hair on the middle segment of any of your fingers, assume you are heterozygous for this trait (Hh). Complete absence of hair indicates a homozygous recessive genotype for this trait (hh). Complete the Punnett Square below and calculate the percentage probability of inheritance: Partner B: Yes or No Probability (percentage) of having Child with finger hair? % Child without finger hair? %

- The flowers of 4 o’clock plants may be red, pink or white. Reds crossed to whites only produced pink offspring. When pink flowered plants were crossed with each other, they produced 113 red, 129 white, and 242 pink. It is hypothesized that these colors are controlled by a single gene pair of incompletely dominant alleles. Is this hypothesis acceptable on the basis of a Chi-square test? Show your solutions below.1. The data are generated from an initial parental cross. One parent displays the disease phenotype and one displays the wild-type (WT) phenotype. The WT parent always has a homozygous genotype. Your task is to perform a chi-square goodness of fit test on each of two F2 data sets, and make a decision, based on your statistical analyses as to which F2 data set provides greater evidence for indicating the correct mode of inheritance. In this problem, the true mode of inheritance is autosomal dominant, homozygous lethal. Evidence is measured in the following ways: the p-value is greater than 0.05, so we do not reject the null hypothesis, and the p-value is closer to 1. A few things of which to be mindful. 1. In the parental generation, the WT parent always has a homozygous genotype. 2. For the autosomal dominant mode of inheritance, the disease gene always homozygous for the disease allele in the parental generation. 3. For the autosomal dominant, homozygous lethal any person with the…A geneticist working on peas has a single plant monohybrid Y/y (yellow) plant and, from a self of this plant,wants to produce a plant of genotype y/y to use as a tester.

During courtship males of the fiddler crab sometimes build sand hoods at the entrances of their burrows, to which they attract females for mating with claw waving and other displays. Researchers are interested to determine how hoods affect male attractiveness. Researchers conducted experiments that controlled for other differences in courtship behavior between builders and nonbuilders by removing hood builders' hoods and adding hood models to nonbuilders' burrows. a) What type of research design was used by the researchers? b) Is it a type of descriptive research or inferential research? Why?Remember that in Pisum sativum, yellow seed color is dominant over the green, and smooth seed is dominant over constricted. In a dihybrid cross experiment, the following data was gathered: 189 green, smooth 178 yellow, constricted 564 yellow, smooth 69 green, constricted Are these genes assort independently based on the observed data? Support your answer using the Chi-square test.

The gene for the vasopressin receptor V1a is expressed at higher levels in the forebrain of monogamous vole species than in promiscuous vole species.11 Can expression of this gene infl uence monogamy? To test this, Lim et al. (2004) experimentally enhanced V1a expression in the forebrain of 11 males of the meadow vole, a solitary promiscuous species. The percentage of time each male spent huddling with the female provided to him (an index of monogamy) was recorded. The same measurements were taken in 20 control males left untreated. Control males: 98, 96, 94, 88, 86, 82, 77, 74, 70, 60, 59, 52, 50, 47, 40, 35, 29, 13, 6, 5 V1a-enhanced males: 100, 97, 96, 97, 93, 89, 88, 84, 77, 67, 61 a. Display these data in a graph.

Which group has the higher standard deviation in percentage of time spent huddling with females?A panel of dentists is interested in testing two different toothpaste brands (A and B) to see if there is a relationship between the brand and whether or not the patient has a cavity at their next appointment. A representative sample of 60 patients is recruited to take part in this study. At their first appointment of the year, each subject is assigned to brush their teeth with one of the two brands for the next six months. At their follow-up appointment six months later, they were checked for cavities. ******In the sample, 6 of the 30 patients assigned to Brand A were found to have a cavity.
