Would two brothers have the simIlar dna?
It is very unlikely that two brothers would have babies with the same DNA. That could only happen if identical twin brothers married identical twin sisters, and even then the mixing of DNA during reproduction makes this an extremely unlikely outcome.
Genetic variety in cells is created through?

Why is there sex in this world?
Sex exists in a biological sense to create diversity and strength among an entire species. To explain, it is easier to contrast sexual reproduction with asexual reproduction. Asexual reproduction occurs when a single parent gives rise to an offspring with a genetic composition that replicates the parent. In such reproductions, all offspring are exact copies of their ancestors, and so there is no variation of characteristics among the population. In effect, the offspring are clones of the parents.Asexual reproduction is very efficient - individuals do not have to seek out a mate to engage in fertilization, and the amount of energy and time expended in reproducing an identical copy is significantly less than for sexual reproduction. 1There is a significant disadvantage to asexual reproduction - there is no diversity within the species. Should the population's environment change, even by a small amount, the change could prove lethal to the entire population. Should a new predator or disease come onto the scene, it could wipe out the entire population. Bacteria are an example of organisms that reproduce asexually. That is why, once a suitable antibiotic is identified, it will treat a bacterial infection by killing all individual bacteria that make up that population. There are no variations, and therefore an entire population is vulnerable to a single antibiotic treatment.In sexual reproduction, a male and a female of the same species divide and then combine their genes, and by doing so, create a unique combination of genetic traits in their offspring. These unique genetic traits in turn give rise to distinct combinations of strength, agility, intelligence, shape, height, hair and eye color, etc., and also give rise to congenital variations, such as resistances to specific infections, susceptibility to certain illnesses, and so on. These variations create diversity among the population, and thereby create a more resilient population, since a single threat has a lower probability of wiping out an entire population compared to a population that reproduces asexually.Sexual reproduction also enables a species to propagate only the most successful qualities in an individual, and to filter out less successful traits. This occurs through two ways. First, those individuals that are too weak or sick to reach the age of sexual maturity will never pass on their genes, thereby creating a built-in mechanism to weed out the least desirable genetic traits. Second, most species exhibit instinctive mating behavior - usually among the males - that includes some type of ritual, contest, or even combat in order to win the right to mate with a partner. These instinctive behaviors create a powerful means to ensure that only the strongest and most suitable individuals win the right to procreate, and thereby keep the entire population strong.Sex, or sexual reproduction, therefore helps a species in two ways:The sexual reproduction itself create greater diversity among a species, and therefore makes the species as a whole more resilient to environmental changes and threats; andThe instinctive mating rituals surrounding sexual reproduction serve to constantly strengthen the overall population in a given species.1 Note that bacteria, and other asexually reproducing organisms, can mutate through reproduction, occasionally giving rise to variations in the species, but mutations that lead to viable organisms are rare and are aberrations to the reproduction process.
In what situations would DNA fingerprinting not be an appropiate tool for identification?
If you have two suspects who are identical twins, and you are trying to find out which one is the killer. Identical twins have identical DNA. However, identical twins do not have identical fingerprints, so you could just get a regular fingerprint sample instead.
What is the difference between asexual and sexual reproduction?
Sexual is physical and asexual is non sexualsexual reproduction is when there are 2 parents (mom and dad) the sex cells from both parents come together (egg from female sperm from male) and create a zygote, the baby. asexual reproduction is with only 1 parent. the parent cell duplicates making another cell. there are 3 types of asexual reproduction; budding, regeneration, and mitosis. budding is when the organism grows on the other organism and when it is fully developed it falls off. Ex: Hydra. Regeneration is an organisms ability to re-grow body parts. Ex: Earth worms or Starfish. Mitosis is when a cell duplicated. there are many steps to it.
What kind of reproduction could you infer from population of identical individuals?
Asexual Reproduction
How could you use asexual reproduction and mitosis in the same sentence?
Cells in the body, apart from the sex cells, reproduce by mitosis, a form of asexual reproduction where the chromosomes are identical in both the parent and the daughter cells.
Competition between members of a woodchuck population in a large field could be expected to increase as a result of an increase in the?
woodchuck reproduction rate
What are the offspring of sexual reproduction related to their parent?
What could be said is that the offspring will not be identical, genetically or regarding appearance; there will be variation between offspring and their sexually reproducing parents.
Would two brothers have the simIlar dna?
It is very unlikely that two brothers would have babies with the same DNA. That could only happen if identical twin brothers married identical twin sisters, and even then the mixing of DNA during reproduction makes this an extremely unlikely outcome.
When will natural selection favor altruism?
Natural selection may favor altruism when the benefits of helping others outweigh the costs to the individual. This can occur in situations where individuals are closely related, as in kin selection, or in reciprocal altruism, where individuals help others with the expectation of receiving help in return. Overall, altruism is more likely to be favored in social species where cooperation and group cohesion enhance the survival and reproduction of individuals.

Would a dominant allele ever return to a population?
If a population does not have a particular dominant allele, it could return to the population through the immigration of new individuals carrying the dominant allele.
In a set of triplets how can two be identical and the other not like the two?
In triplets you could have 3 individuals that came from 3 separate eggs or you could theoretically have 2 eggs fertilized and one of the eggs split in two giving a set of identical twins and the other egg would give you triplets. Theoretically you can have identical triplets, if one of the eggs decided to split a second time (this would be a VERY rare occurance). In that case all of the babies would be identical. In triplets you you can have three individuals that came from three separate eggs, or you could have two eggs fertilized, and one of the eggs splitting to make identical twins while the other egg would give you triplets. If one of the eggs decided to split a second time this would result in identical triplets. [Identical triplets are very rare] only 1 in 1000 triplet births are identical.
Can there be identical puppies?
Yes they could.
Which is a disadvantage of asexual reproduction?
Lack of genetic diversity which may result in destruction of an entire population if there is a change in climatic or environmental conditions; the population does not have a gene pool that may provide some resistant members which could survive
When will you prefer sampling instead of census?
It is a judgment call based on the accuracy required, time allotted and costs. If you need data quickly, at a reasonable cost and time (of course depending on how many individuals there are in the population), you would take a sample. If the population is a reasonable number that all individuals in the population could be used, then go for the census.
