What evidence suggests that epigenetic effects may cause these phenotypic differences in monozygotic twins

Biology
1 answer:
vlada-n [284]3 years ago
4 0

Answer:

Epigenetic marks (e.g., DNA methylation patterns) in older twins are more pronounced than in younger twins  

Explanation:  

Epigenetics refers to any heritable phenotypic change that does not involve alterations in the DNA sequence but impacts gene expression. Epigenetic modifications can be classified into three types: DNA methylation, histone modifications (i.e., acetylation, methylation, phosphorylation, etc) and regulatory non-coding RNA (ncRNAs) pathways. Epigenetic modifications in (epi)genome enable to explain how two individuals with identical genetic material (such as monozygotic twins) can have different phenotypes. In older twins, epigenetic differentiation will be higher than in younger ones due to the divergence between epigenomes as a result of age.

Option A: True

Insectivorous birds such as bluebirds, dippers and flycatchers prefer to eat medium-sized insects. This is because like most birds, they love easy and satisfying meals. To the birds, a medium-sized insect is a good compromise because it is quite easy to chew and digest and at the same time, easy to find.

As a result, most insectivorous birds prefer to get their daily ration of proteins from the medium-sized birds.
