The D and F loci are 18 map units apart on Drosophila chromosome 3. dd mutants have pale brown dilute bristles and ff mutants have furry antennae. A pure-breeding furry fly is crossed to a pure-breeding pale brown dilute fly for the Parental (P) generation. Show the genotypes of P, the F1 and the F1 testcross progeny. Indicate the four testcross progeny phenotypes, and the expected numbers for each phenotype if there are a total of 436 F1 testcross progeny flies. Show your calculations

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.

fumikage isn't really a bird, and tsuyu does have teeth. tsuyu has a transformation quirk which still allows her to be partially human. otherwise we'd have a large frog running around. fumikage has teeth because again, he isn't a bird. his head was a quirk mixture if i'm correct.

they have identical fossils of organisms that have evolved over time.

both have animal fossils preserved in them due to weathering and erosion.

they contain different fossils because life on earth has changed through time.

the fossils in them were formed on the surface of earth due to exposure to sunlight.
