Alleles are also like genes which contain a trait from the parent cells that could be likely passed on to the offspring cells. For example, the trait of having blue eyes of the father and brown eyes of the mother are two alleles. There are probability for these alleles to pass on. 'p' designated the success of one allele to pass on, while 'q' designates a failure. When these two are added up, the sum would be 1. Therefore:
q = 1 - p = 1 - 0.44
q = 0.56
Geographical Isolation is the mechanism that might have led to the appearance of the Hawaiian honeycreeper.
Geographical Isolation is the term used that refers to a population of animals, plants, or other organisms that are separated and unable to exchange genetic materials with other organism of the same species.
Geographical Isolation may be a result of coincidence or accident.
Here are some factors of Geographical Isolation:
1) Isolation by barriers
2) Isolation by distance
3) Isolation after an Event
4) Isolation by separation
There was less of it, making it more possible for the species to be extinct.
Answer: The estimated population is 1250 mice
Explanation: The method use was marked and recapture, in which individuals are marked in the first capture and after some time biologist trap a new group of individuals that can be or not marked
Whit this data is possible to estimate the size of a population applying the Peterson method but is important to make some considerations such as:
1. All indivuals have the same probability to be capture
2, The population remain constant in terms of birth and death rate.
Taking this into account, the formula that allows to determine the size of the population is:
N=CM / R
where N is the size of the population, C is number of indivuals trapped in recapture, M is number of individuals marked in the first capture and R is the number of marked animals trapped in recapture
In this case:
N = 250 * 200 / 40 = 1250
