Which of the following are true statements regarding linkage disequilibrium? Please select all that apply. O Low recombination rate favors linkage disequilibrium. O Alleles at two loci are found together more frequently than could be explained by chance. Alleles don't have to be physically linked in order to be in linkage disequilibrium. Asexual reproduction is very effective at preventing linkage disequilibrium.

Figure 13.4 Which of the following statements is true? Recombination of the body color and red/ cinnabar eye alleles will occur more frequently than recombination of the alleles for wing length and aristae length. Recombination of the body color and aristae length alleles will occur more frequently than recombination of red/brown eye alleles and the aristae length alleles. Recombination of the gray/black body color and long/short aristae alleles will not occur. Recombination of the red/brown eye and long/short aristae alleles will occur more frequently than recombination of the alleles for wing length and body color.

Group of answer choices .45 from mom, .05 from dad .4 from mom, .1 from dad .5 from mom, 0 from dad .1 from mom, .05 from dad
Which of the following statement is TRUE? Recombinants cannot be formed without crossovers. Recombinants can only be formed for linked genes Recombinants can only be formed for alleles that follow independent assortment. Recombinants cannot be formed without crossovers between two linked genes. Recombinants of unlinked genes can only be formed by crossovers.
I am trying to understand how linkage works, and I am hoping someone can explain how to solve the following problem: The diagram shows the linkage maps for four genes: A, B, C, and D. Which genes are most likely to undergo recombination? Which genes are least likely to recombine? A.) A and D B.) C and D C.) B and C
In a diploid plant species, an F1 with the genotype Mm Rr Ss is test crossed to a pure breeding recessive plant with the genotype mm rr ss. The offspring genotypes are as follows: Genotype Number Mm Rr Ss 687 Mm Rr ss 5 Mm rr Ss 68 Mm rr ss 196 mm Rr Ss 185 mm Rr ss 72 mm rr Ss 8 mm rr ss 679 Total 1900 1. Calculate the recombination frequency between each pair of genes
Which of the following statements is TRUE? Positive interference occurs when a crossover in one region of a chromosome interferes with crossovers in nearby regions. The higher the coefficient of coincidence, the higher the degree of interference. Linked genes always exhibit recombination frequencies of greater than 50%. Two genes that are located far from each other on the same chromosome will show a lower frequency of recombination than two genes that are close together on the chromosome. Recombination mapping experiments become more accurate as the distance between genes increases.
