Respuesta :
The least amount of yolk would be found in the egg of option(c) i.e, the eutherian mammal.
A eutherian mammal's egg would have the least quantity of yolk. Because they are among the smallest in the animal kingdom, mammalian eggs are challenging to work with in experiments. For instance, the human zygote is only 100 m in diameter, hardly perceptible to the human eye, and occupies less than a thousandth of the volume of a Xenopus egg. Additionally, it is challenging to gather adequate material for biochemical research because human zygotes are not produced in quantities equivalent to sea urchin or frog zygotes. A female typically ovulates less than ten eggs at a time.
The majority of today's mammalian diversity is made up of eutherian, or "placental," mammals like humans. Monotremes that lay eggs have small "puggles" that emerge from leathery shells, such as the duck-billed platypus. Marsupials, such as kangaroos, koalas, bandicoots, and opossums, give live birth, but their pregnancies are short and their tiny joeys are developmentally immature, making it seem as though they have little need for a placenta.
