Plant breeding Plant breeding has been used for thousands of years, and began with the domestication of wild plants into uniform and predictable agricultural cultigens. High-yielding varieties have been particularly important in agriculture. Selective plant breeding is also used in research to produce transgenic animals that breed "true" (i.e., are homozygous) for artificially inserted or deleted genes.[1 Read more

Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together. Domesticated animals are known as breeds, normally bred by a professional breeder, while domesticated plants are known as varieties, cultigens, cultivars, or breeds.[1] Two purebred animals of different breeds produce a crossbreed, and crossbred plants are called hybrids. Flowers, vegetables and fruit-trees may be bred by amateurs and commercial or non-commercial professionals: major crops are usually the provenance of the professionals. Read more

Child marriage is a marriage or similar union, formal or informal, between an adult and a child or youth under a certain age, typically age eighteen. Child marriage violates the rights of children and has widespread and long term consequences for child brides and grooms. It affects both boys and girls, but it is more common among girls.The legally prescribed marriageable age in some jurisdictions is below 18 years, especially in the case of girls.[citation needed] Even where the age is set at 18 years, cultural traditions may take priority over legislative law and many jurisdictions permit earlier marriage with parental consent or in special circumstances, such as teenage pregnancy. Comprehensive sex education can help to prevent child marriage.[ Child marriage is related to child betrothal, and it includes civil cohabitation and court approved early marriages after teenage pregnancy.[7][8] In many cases, only one marriage-partner is a child, usually the female. Causes of child marriages include poverty, bride price, dowry, cultural traditions, laws that allow child marriages, religious and social pressures, regional customs, fear of remaining unmarried, illiteracy, and perceived inability of women to work for money.[2][9] Read more

Politics is the set of activities that are associated with the governance of a country, state or an area. It involves making decisions that apply to groups of members. It refers to achieving and exercising positions of governance—organized control over a human community, particularly a state.The academic study focusing on just politics, which is therefore more targeted than general political science, is sometimes referred to as politology (not to be confused with politicology, a synonym for political science). In modern nation-states, people often form political parties to represent their ideas. Members of a party often agree to take the same position on many issues and agree to support the same changes to law and the same leaders. Read more
