Answer:
Genotype of offspring = Aabb
Genotype ratio will be 100 % as all the offspring will have the same genotype
Phenotypic ratio = 100% all the offspring will have the same phenotype
Explanation:
Genotype of First parent - AAbb
Genotype of Second Parent - aabb
Gamete of first parent - Ab, Ab, Ab, Ab
Gamete of second parent - ab, ab, ab, ab
All the offspring will have genotype Aabb
Phenotypic ratio = 100% all the offspring will have the same phenotype
Answer:
Well, if all the herbivores disappeared, multiple things could occur. Without anyone keeping plants in check, plants may grow too abundant and may be harmful to the food web. Not only that, but predators that eat herbivors might starve without food. On the plus side, natural resources like water would increase without herbivores drinking/using it.
I hope this helps :)
Explanation:
Genetic variation can be defined as the difference in the DNA sequences between the individuals in the population
<u>Explanation:</u>
- Antibiotic resistance in bacterial populations is caused by natural selection of bacteria that inherit mutations that make them resistant to the antibiotics,this sentence describes the source and preservation of genetic variation.
- The Mutation is one of the genetic variation or disorder, and probably bacteria choose mutation to become repellent to antibiotics
- In some of the cases of spontaneous bacteria have been obtained from other sets of bacteria through the process and make the bacteria repellent to an antibiotic.
- They survive antibiotic treatment and increase in numbers by natural selection.
- Natural selection can be stated as the process in which organism survive and reproduce adapting to the environment
<span>The correct answer is ‘Aristotle’. Aristotle and Plato developed the idea of ranked classification. Ranked classification involves two names, one for the genus and a second part. For example, in ‘Canis lupus’ (wolf), ‘Canis’ is the genus name and shared by all close relatives, and ‘lupus’ is specific to the wolf.</span>
