. Hydatiform moles are growths of undifferentiated tissues that form within the uterus during an abnormalmolar pregnancy. These moles are usually made up ofXX diploid cells, although some can be XY diploids.Surprisingly, all of the DNA in the nuclei of the cellsin the mole is paternal in origin. Most hydatiformmoles are benign, but because they sometimes candevelop into cancers, these moles should be removedsurgically when they are detected.a.

Question
. Hydatiform moles are growths of undifferentiated tissues that form within the uterus during an abnormal
molar pregnancy. These moles are usually made up of
XX diploid cells, although some can be XY diploids.
Surprisingly, all of the DNA in the nuclei of the cells
in the mole is paternal in origin. Most hydatiform
moles are benign, but because they sometimes can
develop into cancers, these moles should be removed
surgically when they are detected.
a. What kinds of events could lead to the generation
of a hydatiform mole?
b. Hydatiform moles are diploid cells with the normal
numbers of genes and chromosomes. Why do you
think they develop as undifferentiated tissues rather
than as normal embryos?
