You perform a backcrossing experiment to map regions of the corn genome that responsible for kernel size. first, you cross true breeding plants with large kernels to true breeding plants with small kernels. the f1 hybrids have medium size kernels. you then backcross the f1 to the parents with small kernels, and you genotype the backcross progeny at 100 marker loci. you observe that progeny that are heterozygous at locus 1 have larger kernels than individuals that are homozygous at locus 1. in contrast, individuals that are heterozygous at locus 2 have the same size kernels as individuals that are homozygous at locus 2. which of the following statements is most consistent with your results? a) both loci 1 and 2 are in linkage disequilibrium with genes that affects kernel size. b) neither locus 1 or 2 is in linkage disequilibrium with a gene that affects kernel size. c) locus 2 is in linkage disequilibrium with a gene that affects kernel size. d) locus 1 is in linkage disequilibrium with a gene that affects kernel size.

Why is it important to reduce the number of chromosomes in half when forming gametes for sexual reproduction?

The accompanying figure shows the percent of selected dna sequences that match between a chimpanzee and other primates. these data support the hypothesis that the figure shows the percentage of selected d n a sequences that match between the chimpanzee and other primates. the human has an almost 98 percent match, the gorilla has an almost 97 percent match, the orangutan has a 96 percent match, the gibbon has an almost 95 percent match, and the old world monkey has an almost 92 percent match. the accompanying figure shows the percent of selected dna sequences that match between a chimpanzee and other primates. these data support the hypothesis that the figure shows the percentage of selected d n a sequences that match between the chimpanzee and other primates. the human has an almost 98 percent match, the gorilla has an almost 97 percent match, the orangutan has a 96 percent match, the gibbon has an almost 95 percent match, and the old world monkey has an almost 92 percent match. chimpanzees and gibbons are the most closely related the chimpanzee's closest surviving relative is humans orangutans are the primates least closely related to chimpanzees old world monkeys and gibbons are the most closely related
