Which of the following is most likely to decrease genetic va

Which of the following is most likely to decrease genetic variation? directional selection mutation stabilizing selection diversifying selection Which of the following is an example of stabilizing selection? The birth weight at which newborn humans are most likely to survive and the average weight of newborn humans are about the same. There is an increase in antibiotic-resistant strains of bacteria. There is an increase in the number of different breeds of dog. Garter snakes with different coloration patterns behave differently when threatened. Which of the following is an example of sexual selection? Bacteria evolve resistance to antibiotics. Cheetahs experienced a population bottleneck. Peahens choose to mate with peacocks that have the most beautiful tails. Female butterflies have a higher survival rate than male butterflies. Ecology is the study of__. life human effects on the environment interactions between humans and other species interactions between

Solution

13 . Stabilizing selection is most likely decrease the genetic variation. [ same species get environmental advantage ]

14. Example of stabilizing selection is there is an increase in antibiotic resistant strains of bacteria. [ it is the same species that have a higher fitness ]

15 . Sexual selection is when female choose among the showiest males. So here the option says \" peahen choose to mate with peacocks that have most beautiful tails.

16. Ecology is the study of interaction between organisms and their environment

17. Rock is an example of abiotic

18. Population [ it consist of same species ]
