Students in ms. fullhart’s class were designing an experiment to test whether the amount of water given to a plant affects the growth in terms of height of the plant. both plants were given the same amount of plant food, and exposure to sunlight. the students decided to use potato plants to conduct their tests. the plants were all the same height when they started the test. the plants were divided into 4 groups of 3 plants each. group 1 plants were given no water, group 2 plants were given 10 ml of water each day, group 3 plants were given 50 ml of water each day, and group 4 plants were given 100 ml of water each day. what are the controls variables (constants)?

This problem has been solved! see the answeryou are investigating two traits in fruit flies controlled by one gene each. the b gene controls for body color (black or brown), while the r gene controls for body sculpture (rugose or smooth). after crossing rugose black flies with smooth brown flies, you obtain an f1 generation of 100% smooth black flies.what are the dominant alleles? (1 pt)what are the genotypes of the two parent flies to perform a dihybrid test cross? (1 pt)after running a dihybrid test cross, you find 1000 offspring with the following phenotypes: , rugose406black, smooth86brown, rugose94brown, smooth4141000fill in the expected column with the expected number of offspring in each class of phenotypes. (1 pt)what phenotype classes represent the recombinant offspring? (1 pt each)calculate the relative genetic distance between the body color gene and the body sculpting gene (show your work). (1 pt).
