What kind of test would best determine whether genotypic frequencies match the Hardy-Weinberg model? Group of answer choices Chi-square with three rows (homozygous dominant, heterozygous, homozygous recessive) Chi-square with two rows (dominant and recessive alleles) T-test between homozygous and heterozygous T-test between dominant and recessive alleles

This 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!
Which of the following statements does NOT apply to the Hardy-Weinberg expression: p2 + 2pq + q2? Group of answer choices p2 is the frequency of individuals with the homozygous recessive genotype. 2pq is the frequency of individuals with the heterozygous genotype. It can be used to determine the genotype and allele frequencies of the previous and the next generations. Knowing either p2 or q2, you can calculate all the other frequencies
In 1-3 sentences each define the follwing terms: complex trait, concordance, environmental variance.
Consider a locus with two alleles, A and a. If the frequency of AA is 0.30, what is the frequency of A under Hardy-Weinberg?
Here's the cheat-sheet below. tt nontaster (homozygous recessive): single band at 221bp TT taster (homozygous dominant): two bands (177bp and 44bp) Tt taster (heterozygous): 3 bands representing both alleles (221bp, 177bp, 44 bp) MARKER tt nontaster TT taster U D Tt taster U D MARKER PBR322/ U D 100 bp ladder BstNI 1857 bp 929 bp 383 bp 121 bp 221 bp 177 bp 44 bp primer dimer if present) This figure shows you expected results for the 3 possible genotypes. The U is for "undigested', meaning what you see before using the restriction enzyme. The D is for digested. Q8) In the figure above, which was the BETTER ladder to use for this experiment? PBR322/BstNI or the 100 bp ladder?
Orange coat color in cats is due to an X-linked allele (XO) that iscodominant with the allele for black (X+). When genotypes at the orangelocus were determined for a sample of cats in Minneapolis and St. Paul,Minnesota, the following data were obtained:XOXO females 11XOX+ females 70X+X+ females 94XOY males 36X+Y males 112Calculate the frequencies of the XO and X+ alleles for this population.
In a population of 200 people, an allele F has a frequency of 84%. What is the frequency of allele f? Using the Hardy-Weinberg equation, estimate the numbers of homozygous dominant, heterozygous, and homozygous recessive genotypes. (Remember that the formula is: p2 + 2pq + q2 = 1, where p represents the dominant allele and q represents the recessive allele.) *Be sure to account for all 200 people in the population.
Regarding the analysis of single marker STR results used in forensic science. Tick all the correct statements: if a suspect's alleles are identical to those collected at a crime scene, then the suspect is possibly guilty dizygotic twins can have similar alleles at an STR locus no correct statement if a suspect's alleles are different from those found at a crime scene, then the suspect is definitely innocent monozygotic twins may have different alleles at an STR locus ☐if a suspect's alleles are different from those collected at a crime scene, then the suspect is possibly innocent ☐two unrelated individuals could have a similar genetic profile monozygotic twins cannot have different alleles at an STR locus dizygotic twins cannot have similar alleles at an STR locus ☐if a suspect's alleles are identical to those collected at a crime scene, then the suspect is definitely guilty
Which of the following is a genotypic frequency? O aa = = 24% O A= 54% O a = 46% O Brown hair = 33%
Which of the following statements are true about penetrance and expressivity? Please make sure to select all correct answer options. O Incomplete penetrance and variable expressivity cannot cooccur for a given allele. Penetrance describes the extent to which individuals with a given allele exhibit the phenotype associated with that allele. OPenetrance and expressivity of a given allele is affected by both environmental factors and genetic backgrounds of different individuals. Expressivity measures the severity of the phenotype.
