The term "pure breeding" comes from the practice of selectively mating individuals with the same or similar genotypes to maintain specific traits or characteristics in offspring. This controlled breeding method is often used in genetics and animal breeding to produce consistent traits in subsequent generations.
true breeding
Pure line selection involves choosing and breeding individuals within a population that display desirable traits to establish a genetically homogenous line that consistently exhibits those traits. This method is commonly used in plant and animal breeding to develop stable and uniform varieties with specific characteristics.
Mendel used the term "parental generation" to signify his true-breeding first generation of plants.
Technically, a non-pure substance is called a compound, so substance should not be used as an official scientific term. If you do come across the term 'substance', use context to decide. e.g. "Scientists isolated the substance boron." would be a pure substance, as boron is a single element.
The term for matter made of only one type of element is "pure substance," while matter made of only one type of molecule is called a "pure compound."
Pure.
Thoroughbred is also a term for a dog or cat of pure breeding. As an example, a poodle is thoroughbred when he is the offspring of two poodles of pure poodle bloodlines.
The selective breeding of pure yeast cultures began in 1883
Selective breeding/ 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.
PBNR in dog breeding means: Pure Bred Non Registered.
Homozygous, or pure bred.
true breeding
Mendel crossed a pure-breeding round-seeded variety with a pure-breeding wrinkled-seeded one. All the peas produced in the second or hybrid generation were round.
You only get pure fire dragon when breeding a fire dragon with a pure dragon. A pure dragon can be bred with two legendary dragons.
A breeding male cat is normally a pure-bread of the species used to impregnate female cats to produce kittens to be sold.
You're probably talking about Homozygous.
