What is the difference between a monohybrid cross and a dihybrid cross? A. A monohybrid cross involves a single parent, whereas a dihybrid cross involves two parents. B. A monohybrid cross produces a single progeny, whereas a dihybrid cross produces two progeny. C. A monohybrid cross involves organisms that are heterozygous for a single trait, whereas a dihybrid cross involves organisms that are heterozygous for two traits. D. A monohybrid cross is performed only once, whereas a dihybrid cross is performed twice.

In your own words, explain why a testcross cannot produce more than 50% recombinant offspring. When a testcross does produce 50% recombinant offspring, what does this result mean?

Morgan observed a higher number of recombinant offspring involvingeye color and wing length (401 + 318) than recombinants forbody color and eye color (17 + 12). These results occurred because a. the genes affecting eye color and wing length are fartherapart on the X chromosome than are the genes affectingbody color and eye color.b. the genes affecting eye color and wing length are closer togetheron the X chromosome than are the genes affectingbody color and eye color.c. the gene affecting wing length is not on the X chromosome.d. the gene affecting body color is not on the X chromosome.
