It would be completely false to say that both internal and external environments can modify or alter a gene. The correct option among the two options that are given in the question is the second option or the last option. I hope that this answer has come to your great help.
A genotype is an organisms genetic makeup and they are represented by 2 alleles (letters). An example of a genotype would be AA, Bb, and CC. Since there is 2 heterozygous offspring the dominant allele will hide the recessive allele which makes both of them have long antennas.
For most athletes, the period in their
yearly training cycle during which it is recommended to begin calorie restriction
so as to lose significant amounts of stored body fat is the off-season or early
in the preseason. Restriction of energy intake late in the preseason when
there is rigorous training or during season when there is competition may impede training, recovery,
or performance.
