Answer:
d. recessive epistasis
Explanation:
Recessive epistasis is a genetic phenomenon where the recessive gene is able to repress the expression of the dominant gene, presenting a greater number of individuals with the recessive genotype, in the F2 generation, than the number of individuals of the dominant genotype.
An example of this can be seen in the question above, where the F2 generation contained 178 purple, 60 red and 80 white flowers. The white color represents the recessive allele, while the red color presents the dominant allele. The recessive allele was expressed in greater quantity indicating the occurrence of recessive epistasis.
Answer:
Blood absorbs and distributes heat throughout the body. It helps to maintain homeostasis through the release or conservation of warmth. Blood vessels expand and contract when they react to outside organisms, such as bacteria, and to internal hormone and chemical changes.
Natural selection is a central concept of evolution. Natural selection is the process where organisms with favorable traits are more likely to reproduce. In doing so, they pass on these traits to the next generation. Over this time this process allows organisms to adapt to their environment.
