A zygote is the product of fertilization. The diploid zygotes of the four organisms seen here all underwent __________ and _____________ in order to produce the four very different embryos.
A) meiosis; mitosis
B) mitosis; differentiation
C) meiosis; differentiation
D) differentiation; specialization

Respuesta :

A zygote is the product of fertilization. The diploid zygotes of the four organisms seen here all underwent mitosis and differentiation in order to produce the four very different embryos. The differentiation of cells during embryogenesis is the key to cell, tissue, organ, and organism identity. Once an egg is fertilized by a sperm, a zygote is formed. The zygote divides into multiple cells by mitosis, triggering the beginning of embryonic differentiation.

Answer:

mitosis; differentiation

Explanation:

Mitosis is a process of cell division where a cell produces two daughter cells of the same ploidia. When the fusion of haploid sexual gametes (ovule and sperm) occurs, a diploid zygote is formed. Once the zygote is formed, the embryogenesis -process responsible for forming the embryos- start. The Embryonic development consists of multiple mitosis that allows the formation of a multicellular organism from a single cell. Mitosis is accompanied by programmed cell differentiation, a mechanism by which specialized and differentiated tissues are generated. This mechanism allows, for example, the differentiation of bone tissue from muscle. Meiotic recombination during the gamete formation process (before fertilization) will allow the offspring of the same father and mother to be genetically variable.
