If cell x enters meiosis, and nondisjunction of one chromosome occurs in one of its daughter cells during meiosis ii, what will be the result at the completion of meiosis? a. ¼ of the gametes descended from cell x will be n+1, ¼ will be n-1, and ½ will be n. b. half of the gametes descended from cell x will be n+1, and half will be n-1.c. all the gametes descended from cell x will be diploid. d. two of the four gametes descended from cell x will be haploid, and two will be diploid.

Duchenne muscular dystrophy is a serious condition caused by a recessive allele of a gene on the human x chromosome. the patients have muscles that weaken over time because they have absent or decreased dystrophin, a muscle protein. they rarely live past their twenties. how likely is it for a woman to have this condition? a) women can never have this condition.b) one-fourth of the daughters of an affected man would have this condition.c) one-half of the daughters of an affected father and a carrier mother could have this condition.d) only if a woman is xxx could she have this condition.

The images show two species of tree frogs in a particular region. the gray tree frogs are adapted to the trees of the woodlands, while the green tree frogs can survive in woodlands or grasslands. the gray frog was abundant in the woodlands. because of climatic changes, most of the trees in the region died, and the woodlands changed to grasslands. in such a case, the . the gray tree frog is closely related to the green tree frog genetically, but they have different mating calls. this suggests that speciation occurred because of .
