<h2>Inbreeding </h2>
Explanation:
Inbreeding is defined as the formation of offspring which results from the mating of two closely related organisms
Inbreeding affects allele frequencies and genotype frequencies in a population in following ways:
- Inbreeding increases homozygosity
which in turn decreases the biological fitness of a population because there are chances that offsprings will be affected by deleterious traits in this case
- Inbreeding itself does not cause evolution, because allele frequencies do not change in the population as a whole
Answer:
meiosis I
Explanation:
Independent transmission is Mendel's second law. Like any Mendel law it is based or is about the transmission of alleles. Therefore, the law of independent transmission is based on the fact that when forming gametes, the alleles of one gene are segregated independently before the segregation of the alleles of another gene. This second law can not only be applied to the characters that Mendel analyzed, which were two genes with two possible alleles, this law is fulfilled with more than two characters. We must bear in mind that alleles are the different forms that a gene can present.
On the other hand we have the concept of meiosis I which is a type of cell division that in animals generally gives rise to gametes for sexual reproduction or sexual spores (in plants and fungi). That is to say in mitosis we find that there is only a cell division between homologous chromosomes, so that from a tetraploid number (4n) we pass to a diploid number (2n). While in meiosis we find that there are two cell divisions in which we go from a tetraploid number (4n) to a haploid number (n). This means that this is a reductive process. These haploid cells will join together to give rise to a diploid cell. Another important concept to consider in meiosis is the formation of chiasmas that are created between non-sister chromatids, thanks to this phenomenon the exchange of genetic material occurs.

Quit smoking, The process of giving up tobacco use is known as smoking cessation, also referred to as quitting or halting. Nicotine, which is addictive and can lead to dependency, is present in tobacco smoke. As a result, withdrawal from nicotine frequently makes quitting difficult.
The first three days after quitting, when symptoms normally reach their climax, are followed by a period of around two weeks. It gets a little simpler when you get past those difficult first few weeks. What aids? Before quitting, you should start to create arrangements. What occurs when a smoker stops? Your breathing and capacity for exercise will start to dramatically improve.
Your chance of having a heart attack is greatly reduced. Your risk of developing laryngeal, throat, and mouth cancer is halved, and your risk of stroke is reduced. When compared to a smoker, your risk of acquiring lung cancer is decreased by half.
