Samantha is an epigeneticist. She is currently working on a research project that identifies epigenetic factors. Which two of these factors could her project include?
an altered gene sequence
cell samples l
methods to observe the effects of climate on gene mutations
technology to detect inherited genetic diseases

cell samples

methods to observe the effects of climate on gene mutations

Explanation:

Epigenetics can be described as the field of genetics under which those heritable phenotype characteristics are studied which are not influenced by alternations in the genetic makeup or DNA sequence of the individual.

As altered gene sequences and genetic diseases depend on the changes in the DNA hence, option A and D are not correct.

Cell sample and studying the effects of climate on gene mutations are not related to the alternation of DNA and hence are correct options.

common management practices in dairy and poultry farming are: (i) proper shelter facilities and their regular cleaning. (ii) some basic hygienic conditions such as clean water, nutritious food, etc. (iii) animals are kept in spacious, airy, and ventilated place.
