In the case of humans, the father's 1n gamete contains 23 chromosomes and the mother's 1n gamete contains 23 chromosomes. When fertilization occurs the zygote (fertilized egg) now has 23+23, or 46 chromosomes for a normal, human, diploid (2n) cell. It is important to note that the ...
For example, some types of dwarfism in humans are actually a dominant trait, but it is still considered a mutation because it is not the majority of the population. Wild type is defined by the frequency of the allele in the natural population. Any time it is the majority (more than 50%...
. To put it simply, the range of variation is in a bell-shaped distribution pattern. Thus, polygenes allow a large number of possibilities in terms of phenotypic traits.Polygenic Inheritance Examples Many human traits are polygenic. The expression of polygenic traits in humans is exemplified by ...
Figure 2: The different ABO blood groups in humans. Notice the specific antigens in the red blood cells of blood types A, B, AB, and O. Blood type A has A antigen. Blood type B has a B antigen. Blood type AB has A and B antigens. Blood type O lacks A and B antigens on th...
In fitness, this could be the heaviest weight lifted, the fastest time running a certain distance or the most number of repetitions completed of an exercise. A fitness goal or PR providesmotivationto keep pushing oneself and strive for continuousimprovement. There are two main types of PRs: abs...
In the context oftime-series continuous datasets, the normal or expected value is the baseline. The limits around that baseline represent the tolerance associated with the variance. If a new value deviates above or below these limits, then we can consider that data point to be anomalous. ...
It occurs in all living organisms including humans and plants. The mechanisms used for vertical gene transfer include mitosis and meiosis. Mitosis is the division of a cell into two identical daughter cells that have the same number of chromosomes as the original parent cell. Meiosis is when a...
In humans, polygenic inheritance is classically exemplified by height and skin color, two traits which we know have a wide range of possibilities. If you were to map out the different phenotypic classes that could result from a trait like human height, you would get a bar graph that ...
If the frequency varies from one item to another, the mode is the value that appears most frequently. In the case of continuous variables the frequency depends upon how many digits are quoted, so the mode is more usefully considered as the midpoint of the class with the largest frequency. ...
