Using the thick blood film to detect malaria enables observation od parasite morphology and it is used to quantify and identify parasites to the species level. For that kind of detection a high-power microscope (400 times to 1,000 times magnification) is required. The microscopist can look for parasites in a relatively large volume of blood, thus increasing the sensitivity of the test.
Answer:
1 in 16
Explanation:
When two heterozygotes (AaBb x AaBb) for two autosomal genes are crossed the expected probability for the offspring is 9 A-B-, 3 A-bb, 3 aaB- and 1 aabb. In other words, out of sixteen offspring, 9 are expected to be dominant on both genes (either homozygous AA or BB or heterozygous Aa or Bb), 3 are expected to be dominant on the A gene but recessive on the b gene, 3 are expected to be recessive on the a gene but dominant on the A gene, and only 1 is expected to be recessive on both genes aabb.
