Common medical problems such as heart disease, type 2 diabetes, and obesity do not have a single genetic cause—they are likely associated with the effects of multiple genes (polygenic) in combination with lifestyle and environmental factors.
Answer:
chromosomes r the threadlike structure found in the nucleus of living cells, carrying genetic information in the form of genes.
Mutations induced by UV.
The answer is option A.
They have a defect of their "curly gene," that's on the second chromosome. Having curled wings is a dominant mutation, this means that only one copy of the gene must be altered to supply the disorder. In reality, if both copies are mutated, the flies do not continue to exist.
Geneticists have lengthily counseled that mutations in insect pigment genes reason for modifications in the fly's brain because these pigments are crafted from dopamine, a chemical messenger that acts in the brain.
Thru those early experiments, he located that every one of the white-eyed flies being produced was a man, there were no white-eyed women in any respect. Inheritance of the white-eye trait might have a basis within the chromosomes, greater, in particular, the sex chromosomes.
