Question

You buy a pie that contains a swirled mixture of chocolate and vanilla filling. When you cut the pie up, you notice that some slices have more chocolate than vanilla and that other slices have more vanilla than chocolate.
This uneven distribution of chocolate and vanilla is most like the uneven distribution of:

a. Nuclei in a zygote.
b. Nuclei in an early embryo.
c. Nuclei in an egg.
d. Cytoplasmic determinants in a zygote.
e. Cytoplasmic determinants in an early embryo.

Answer 1

d) option is correct

Explanation:

The unfertilized egg contains various organelles and a liquid solution that fills the cell which is called the cytoplasm

Within that cytoplasm are various molecules containing genetic information or chemicals to spark various reactions, called cytoplasmic determinants

Some are different kinds of proteins, most are molecules of RNA and these determinants are unevenly distributed across the egg and then, once it's fertilized, the zygote

Once this zygote undergoes cleavage division, all of these random determinants that were in the same cell are suddenly in different blastomere cells, which means that these blastomeres each contain a different assortment of molecules
