What is an expected complication associated with triploidy resulting from a diploid egg?

Triploidy, characterized by an extra set of chromosomes, can lead to various complications during fetal development. When triploidy results from a diploid egg, one of the most expected complications is intrauterine growth restriction (IUGR). This condition occurs because the abnormal chromosomal makeup profoundly affects cellular growth and differentiation, ultimately leading to insufficient nutrient and oxygen delivery to the developing fetus.

In triploidy, the presence of an additional set of chromosomes can disrupt normal fetal development, affecting organ growth and function, which contributes to IUGR. Premature placental insufficiency is also a factor in triploidy pregnancies, exacerbating the growth restriction.

Other options mentioned, such as hydatidiform moles, extreme short stature, and regular fetal abnormalities, may relate to genetic and chromosomal abnormalities but do not specifically correspond as direct complications primarily associated with triploidy resulting from a diploid egg. Hydatidiform moles relate more closely to abnormal placentation rather than the broader implications of triploidy. Extreme short stature is typically associated with specific syndromic conditions rather than triploidy itself, and "regular fetal abnormalities" is too vague and does not specify the particular nature or extent of abnormalities seen in triploidy.
