Cross breeding involves mating two unrelated individuals from different breeds or populations to produce offspring with a mix of traits. Inbreeding involves mating individuals that are closely related, such as siblings or parent-offspring, which can lead to an increase in genetic defects or expression of negative traits due to the lack of genetic variation.

Describe the difference between a true-breeding individual and a hybrid?
A true-breeding individual consistently produces offspring with the same traits as the parent when self-pollinated or crossed with another true-breeding individual. In contrast, a hybrid is the result of crossing two genetically different parents and exhibits a combination of traits from each parent.
Explain the difference between self-pollination and cross-pollination?
Self-pollination is the inbreeding process occurring in between two flowers of the same plants, in this pollens are transferred from the anthers to the stigma. Cross-pollination is the outbreeding process between the two plants of the same species and of different flowers, in this also the pollens are transfers from the anthers to the stigma.
What is pure breeding?
Pure breeding refers to the practice of mating individuals within the same breed that consistently produce offspring with the same desired traits. This method helps maintain the characteristics of a specific breed or line over generations through selective breeding. Pure breeding is often used in agriculture and animal husbandry to standardize traits such as size, color, or productivity.
What is the difference between a monohybrid and dihybird cross?
A monohybrid cross involves the study of one trait or gene, whereas a dihybrid cross involves the study of two traits or genes simultaneously. In a monohybrid cross, only one pair of alleles is considered, while in a dihybrid cross, two pairs of alleles are considered.
When is it useful to draw a genetic cross diagram?
Drawing a genetic cross diagram is useful when you want to visualize the possible outcomes of a genetic cross between two individuals or organisms. It helps in predicting the genetic composition and potential traits of the offspring. This is often used in genetics research, breeding programs, and understanding inheritance patterns.
What are the two types of selective breeding?
The two types of selective breeding are inbreeding and outbreeding. Inbreeding involves breeding closely related individuals to emphasize specific traits, while outbreeding involves breeding unrelated individuals to introduce genetic diversity.
What is the difference between a mongrel and a crossbred?
A mongrel is a dog of unknown breeding, a crossbred is the cross of two seprate breeds, Ie a Labradoodle, a labrador and a poodle,.
What are the dangers of cross breeding or inbreeding cattle?
It is FAR more dangerous to inbreed cattle than to crossbreed them. Inbreeding exposes genetic abnormalities that would only be exposed if a hetero cow was crossed with a hetero bull for a particular genetic abnormality. Inbreeding is only done if you are mating siblings, daughter to sire, son to dam, cousins, son to granddam, daughter to grandsire, etc. It can also kill your herd as far as productivity is concerned because the more you inbreed, the worse-quality your cattles' offspring will be. Crossbreeding on the other hand, occurs when you breed a different breed a bull to a breed of cow: for instance, breeding a Black Angus bull to a Hereford cow. The offspring that comes with this cross is the exact opposite of inbreeding: you get a very vigorous, high-productive calf that will excel above either of his parent's breeding in the feedlot or in the breeding herd. Generally cross-bred animals live longer and are much better-quality than those breeds that it came from. If you want a herd with great-quality cattle, use cross-breeding.

it counts only to cross breeding, in my opinion.
