In general, the frequency of a particular trait or allele (such as the "bb" allele) in a population can change over time as a result of various evolutionary processes, including natural selection, genetic drift, and mutation.

The study of genes, genetic diversity, and heredity in organisms is known as genetics. It is a significant field of biology since heredity is essential to the evolution of organisms. Gregor Mendel, a Moravian Augustinian monk working in Brno in the nineteenth century, was the first to do scientific research on genetics. The fundamental unit of inheritance passed down from parent to kid. Genes are made up of DNA sequences that are ordered one after the other in the nucleus of cells at specified positions on chromosomes.

Here,

It depends on the specific scenario you are referring to. Without more context, I cannot provide a specific answer to whether the frequency of the "bb" individuals decreased with successive generations. For example, if the "bb" individuals have a disadvantage compared to the "Bb" or "BB" individuals in terms of survival or reproduction, the frequency of the "bb" individuals may decrease over time as a result of natural selection.

On the other hand, if the "bb" individuals are neutral or have an advantage, the frequency may increase.

The relationship between flowering plants such as a fig tree and pollinating insects such as fig wasps is an example of mutualism, where both species benefit from the interaction.

In this relationship, the fig tree relies on the fig wasp to pollinate its flowers, as the flowers of the fig tree are not accessible to other pollinators and are only receptive to the fig wasp. The fig wasp, in turn, relies on the fig tree for food and a place to lay its eggs.

The female fig wasp enters the fig through a small opening and lays her eggs inside. As she does so, she also pollinates the flowers, allowing the fig tree to produce seeds. The fig wasp larvae then feed on the fig's reproductive structures, completing their life cycle inside the fig.

When the fig wasp larvae are ready to pupate, they create small exit holes in the fig, allowing the next generation of fig wasps to emerge and continue the cycle.

This mutualistic relationship benefits both the fig tree and the fig wasp, as the fig tree is able to produce seeds and the fig wasp is able to complete its life cycle. This type of interaction between plants and insects is a common example of pollination, where the two species have evolved to work together in order to ensure their survival.

Polar compound happen when two iotas don't share electrons similarly in a covalent bond. A dipole structures, with a piece of the particle conveying a slight positive charge and the other part conveying a slight negative charge. This happens when there is a contrast between the electronegativity upsides of every iota. An outrageous contrast shapes an ionic bond, while a lesser distinction frames a polar covalent bond.

Luckily, you can look into electronegativity on a table to foresee whether particles are probably going to frame polar covalent bonds. On the off chance that the electronegativity distinction between the two molecules is somewhere in the range of 0.5 and 2.0, the iotas structure a polar covalent bond. In the event that the electronegativity distinction between the molecules is more prominent than 2.0, the bond is ionic. Ionic mixtures are very polar particles.

According to the equilibrium model of island biogeography, a balance between immigration and extinction determines the species richness on an island. This hypothesis has been backed by studies done in the West Indies, which demonstrate that the rate of extinction and immigration control the number of species on an island.

Robert MacArthur and E.O. Wilson originally put out the equilibrium model of island biogeography in 1967. It claims that the equilibrium between immigration and extinction determines the number of species on an island. Migration of species to an island is referred to as immigration, whereas local extinction is referred to as extinction.

This hypothesis has been backed by studies done in the West Indies, which demonstrate that the rate of extinction and immigration control the number of species on an island. For instance, due to the inflow of new species, islands that get more immigrants typically have higher species variety. Moreover, islands with greater rates of extinction tend to have less variety in their species. This is because of the loss of existing species.

Some islands have a higher species diversity than others, which is explained by the balance between immigration and extinction. As a result of their adaptation to the unique environment of each individual island, it also helps to explain why species in the West Indies tend to be more specialized. The equilibrium model of island biogeography, which also explains why some islands remain isolated because they don't receive enough immigrants or lose too many species to extinction, helps to explain why certain islands remain isolated.
