Blood cells, for example, tend to have the highest rates of skewing due to the extremely high dividing and replacement rate within the human body. [9] The strength of selection can also vary depending on the gene under selection, and so skewing can occur at different rates and to different extents.
Fertility rates must level off to the replacement rate (the net reproduction rate should be 1). If the fertility rate remains higher than the replacement rate, the population would continue to grow. 2. Mortality rate must stop declining, that is, it must remain constant. 3. Lastly, the age structure must adjust to the new rates of fertility and ...
In cell biology, protein turnover refers to the replacement of older proteins as they are broken down within the cell. Different types of proteins have very different turnover rates. A balance between protein synthesis and protein degradation is required for good health and normal protein metabolism.
The gross reproduction rate (GRR) is the average number of daughters a woman would have if she survived all of her childbearing years, which is roughly to the age of 45, subject to the age-specific fertility rate and sex ratio at birth throughout that period. This rate is a measure of replacement fertility if mortality is not in the equation. [1]
The estimated “replacement fertility rate,” or the number of births required to maintain or increase the population, is 2.1 live births per woman. While the fertility rate was just above this ...
