Using the information from problem 4, scientists do a further testcross using a heterozygote for height and nose morphol- ogy. the offspring are tall-upturned snout, 40; dwarf-upturned snout, 9; dwarf-downturned snout, 42; tall-downturned snout, 9. calculate the recombination frequency from these data, and then use your answer from problem 4 to determine the correct order of the three linked genes.

because the asteroid belt is between the mars and jupiter orbits, it is around 2.2 to 3.2 astronomical units (au) from the sun – which is approximately 329,115,316 to 478,713,186 km. the average distance between objects is a massive 600,000 miles.

explanation:

answer; the tunica intima also called tunica interna, consists of elastic fibers,connective tissue and smooth muscle cells;

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
