It is the common type of pregnancy loss or spontaneous abortion, it is the natural death of an embryo or fetus before it is able to survive independently.
Answer:
logging, and oil exploration
Explanation:
An example of a complex trait is
weight.
Complex trait or quantitative trait is a trait that doesn’t behave according to simple Mendelian inheritance laws. These traits show a continuous range of variation and are influenced by both environmental and genetic factors. It is often said that complex traits<span> are those that are influenced by more than one factor.</span>
Answer:
A population bottleneck occurred, altering the resulting allele frequencies.
Explanation:
A population bottleneck occurs when the size of a population is reduced by at least a generation. In this case, genetic drift acts more quickly to reduce genetic variation in small populations, but going through a “bottleneck” can greatly reduce variation, even if the bottleneck does not last for many generations. This effect called a bottleneck usually happens when a major disaster occurs in the population's habitat, changing the allelic frequencies and even the genetic variability of the population.
The population bottleneck can be seen in the question above, where after a forest fire, only 20 beetles remain in a population of beetles. 18 of them are green and 2 of them are brown.
Hey there,
Earth radius: 6371 km
"Actual" depth = 6371 x 0.01 / 20 = 3.2 km
