If a species is said to be extinct, then that species is reduced to zero. There are none living in existence. The affects to other organisms of its extinction would depend on their value to the ecosystem. Regardless, extinction completely stops evolution of the species extinct.
DNA is a COMBINATION of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base.
This is the law of dominance in genetics. The dominant allele will mask the effects of the
recessive allele and therefore will be the visible trait of the phenotype. Most often, the dominant allele codes for functional proteins, while the recessive does not code for functional proteins. Dominance in genetics is
significant in Mendelian inheritance.
Answer:
D
Explanation:
This is the more likely explanation, as there must be a limit to leg length in an animal that has to run very fast and strain their muscles and bones to the limit to do so.
As for the other options, there is no evidence to conclude that the genes that are involved in cheetahs leg length do not undergo mutation because the population exhibits a variety of leg lengths. Neither can we conclude that there are any isolated subgroups in the pupulation. Natural selection does act upon the traits involved in predation, as the question starts by saying that the faster a cheetah can run the more likely it is to capture its prey.
