The answer is (b.) fertilization
The fertilization is the stage where the egg cell or the
so-called ovum fused with the sperm cell which eventually leads the development
of the embryo or the zygote. The Embryogenesis starts when the zygote undergoes
mitotic divisions or also known cleavage process.
Answer:
1. d. changes in the methylation patterns of <em>loci</em> involved in growth and metabolic disease
2. b. differences in the expression of metabolic genes
d. changes in histone acetylation patterns
Explanation:
Epigenetics refers to the study of heritable changes in gene expression which are not dependent on DNA sequence. Epigenetic mechanisms involve DNA methylation, histone modifications (acetylation, methylation, phosphorylation, etc) and regulatory non-coding RNA (ncRNA) pathways. These epigenetic mechanisms work together and mutually reinforce each other in order to modulate gene expression (either by activating or suppressing gene expression). In consequence, transcriptome data (e.g., genes differentially expressed in particular tissues/cells or stages of development) is an important piece of evidence indicating the existence of epigenetic modulation.
I’m not gonna write a paragraph but i’ll give a hint. it has to do with people growing, animals hunting , and climate
