A reverse backcross is a crossing throw made in front of the body, where the object is caught behind the back after going back over the shoulder on the same side it's thrown from.
By crossing A with either P1 or P2, you produce a back-cross (P1A or P1B), either cross resulting in a first generation back-cross (BX1). A reverse back-cross is a back-cross that involves a female pollen donor.
Backcross is also called the topcross. Example – When we cross a pea plant consisting Green colour pod YY with a pea plant consisting yellow coloured pod yy. Green coloured pod is dominant over the yellow coloured pod.
The purpose of a backcross is to recover elite genotypes and to produce offsprings that are genetically similar or closer to parents.
Bred by Ethos Genetics, Crescendo crosses Chemdog, I-95, and Mandarin Cookies to create this THC-dominant hybrid. Its terpene profile produces sweet, earthy, and citrus aromas with gassy, kushy, and sweet cookie dough flavors. Buds are large in size and mostly green with purple accents.
Godfather OG - Quick Overview
Labs put the strain's THC levels at a tremendous 30-35%. In fact, Godfather OG is touted as the world's strongest marijuana strain. This potent strain is an Indica-dominant hybrid and hits within minutes of taking the first smoke.
Backcrossing can be defined as a crossing of a hybrid with one of its parents or an individual genetically similar to its parent, in order to achieve offspring with a genetic identity which is closer to that of the parent.
Each line in an IBC population is inbred and can be propagated simply by self-pollination. The population can be replicated. Since each entry of the population is a line and not an individual, traits can be measured on a plot basis rather than an individual plant basis.
This is done by crossing a donor parent to an elite line, and crossing offspring with the 'desired gene(s)' back to the elite parent. The parent to which successive backcrosses are made in backcross breeding.
Backcrossed hybrids are sometimes described with acronym "BC"; for example, an F1 hybrid crossed with one of its parents (or a genetically similar individual) can be termed a BC1 hybrid, and a further cross of the BC1 hybrid to the same parent (or a genetically similar individual) produces a BC2 hybrid.
Merits of Backcross Methods: 1) The genotype of new variety is nearly identical with that of the recurrent parents. 2) It is not necessary to test the variety developed by this method, because the performance of recurrent parent is known. 3) It is not depend upon environment.
The test cross helps in verifying the laws of inheritance. II. Definition of back cross : A cross between an F1 offspring with either of its parents is called a back cross.
In backcross method of breeding, the hybrid and the progenies in subsequent generations are repeatedly backcrossed to one of the parents. As a result, the genotype of the backcross progeny becomes increasingly similar to that of the recurrent parent.
This is called selective backcrossing. This technique allows breeders to introduce new traits into their crops, thereby improving crop quality and providing a variety of options for farmers.
The closest type of inbreeding is selfing, or self-fertilization, the union of male and female sex cells produced by the same organism. Linebreeding is a form of inbreeding that involves selection of mates on the basis of their relationships to a certain superior ancestor.
History of Inbreeding in Humans
Some research shows that the whole human race was down to a few thousand people around 70,000 years ago. With such a small group, there was definitely a lot of inbreeding going on. In fact, this “bottleneck” in population size is probably why humans have so much DNA in common.
The back cross is of two types; they are dominant back cross and recessive back cross.
In some cases, both parents provide the same allele of a given gene, and the offspring is referred to as homozygous ("homo" meaning "same") for that allele.
In short. In hybrid breeding, two genetically different parent lines are produced. Advantages. The offspring (hybrids) are bigger, more fruitful and more resilient than their parental lines (hybrid vigor).
The four types of strain are longitudinal strain, lateral strain, volumetric strain and shear strain.
The strongest Indica strains are Hindu Kush, Granddaddy Purple, and Indica Crystal Extreme for their high 20-30% THC levels. However, determining the strongest Indica strain really depends on the user and their unique body chemistry.
Pakistan Chitral Kush: This strain is 100% indica and it grows in the wild in a Pakistani province called Khyber Pakhtunkhwa. It stands out due to its spectacular resin production, making this plant one of the most used in as far as hash extractions.
