You perform a test cross of the dihybrid aabb with a double homozygous aabb, and you score the phenotypes of 1000 progeny. if genes a and b are completely genetically linked (i. e., no recombination between loci), what offspring counts do you expect to observe? all 1000 with the ab phenotype. all 1000 with the ab phenotype.250 with the ab phenotype, 250 with the ab phenotype, 250 with the ab phenotype, and 250 with the ab phenotype. all 1000 with the ab phenotype500 with the ab phenotype, and 500 with the ab phenotype.

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

answer: andy garner, a 17-year-old who decided to become a human guinea pig in 1965 and go without sleep for 11 days. by the second day his eyes had already stopped focusing, and he lost the ability to identify objects by touch. by day three he was moody and uncoordinated and by the end he had trouble with short term memory and had even started hallucinating.

and a rare genetic mutation called fatal familial insomnia, where people can’t sleep at all, gets progressively worse over months or years and leads to dementia and death.

a devoted soccer fan died after staying awake 48 hours to watch the world cup, she said. ‘while his untimely death was due to a stroke, studies show chronically sleeping fewer than six hours a night increases stroke risk by 4 1/2 times compared with those getting a consistent seven to eight hours.'
