Answer:
Because genetic drift (Founder effect) is acting on this population. Not all the Hardy weinberg criteria are accomplished. There are no random matings and populations are finite-sized.
Explanation:
This is a special case of genetic drift: the founder effect.
The “Founder effect” phenomenon refers to cases where a new population originates from a few founder individuals, coming from a bigger ancestral population, that established in a new environment. This small population might or might not be genetically representative of the original one. This subgroup carries with them some genetic information that they share with their original population. Over time, some genes can be lost, or they can increase in frequency. Some rare alleles might be exceeded or might be completely lost. On Consequence, when the small population grows, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced and enhances the possibility of developing a peculiar allelic composition. In some cases, the founder effect is part of the process of speciation.
The criteria for maintaining a Hardy-Weinberg equilibrium are:
- Random matings
- No superposed generations
- No mutations
- No migration
- Infinite population size
- No natural selection
Genetic drift involved the un-accomplishment of random matings and infinite population sizes.
Genetic drift involves:
- limited population sizes
- individuals reproduce by endogamy/exogamy, and matings occur by phenotype.
Answer: 31,000 meters (m) or 31 kilometers (km)
Explanation:
6,000 meters + 4,000 meters + 12,000 meters + 8,000 meters=31,000 meters
Simplified explanation: 6+4+12+8=31
Answer: B. fallopian tubes
Explanation:
Fallopian tubes - consist of two channels that are located laterally to the uterine horns, and are responsible for capturing the female gamete released by the ovary into the peritoneal cavity, and its conduction to the uterus. For this, the tubes perform peristaltic movements and have eyelashes that push the gametes to the uterus. The fallopian tubes are attached to the upper part of the broad ligament, which is called mesosalpinx.
The sperm meets the ovum in the fallopian tube, and then they go into the uterine cavity. When this does not occur, there is an ectopic pregnancy because the development of the fetus occurs in the tube's ampoule, a phenomenon known as tubal pregnancy, which can culminate in the rupture of the fallopian tube, a situation that causes major bleeding.
Answer:
4900 J
Explanation:
Potential energy is the product of the mass, gravitational constant and the height of the object.
U=mgh=10 kg×9.8 m s^(-2)×50 m=4900 J
So, the potential energy of the object is 4900 J.
Answer:
They are likely to have evolved from similar ancestors.
