A monohybrid cross is a cross between two organisms with different variations at one genetic locus of interest. [ 1 ] [ 2 ] The character(s) being studied in a monohybrid cross are governed by two or multiple variations for a single location of a gene.
The forked-line method (also known as the tree method and the branching system) can also solve dihybrid and multi-hybrid crosses. A problem is converted to a series of monohybrid crosses, and the results are combined in a tree. However, a tree produces the same result as a Punnett square in less time and with more clarity.
In conducting a monohybrid cross, Mendel initiated the experiment with a pair of pea plants exhibiting contrasting traits, one being tall and the other dwarf. Through cross-pollination, the resulting offspring plants manifested the tall trait. These first-generation hybrids were termed F1, with their offspring referred to as Filial or F1 progeny.
Mules and hinnies are examples of reciprocal hybrids. Kunga, a cross between a donkey and a Syrian wild ass. Zebroids. Zeedonk or zonkey, a zebra/donkey cross. Zorse, a zebra/horse cross; Zony or zetland, a zebra/pony cross ("zony" is a generic term; "zetland" is specifically a hybrid of the Shetland pony breed with a zebra) Superfamily ...
As a result, few dominant embryonically lethal alleles are documented as they would never show up in the population. [8] An example in humans of a dominant lethal allele is Huntington's disease, a rare neurodegenerative disorder that ultimately results in premature death. However, because of its late-onset (i.e., often after reproduction has ...
Aaron Rodgers and the New York Jets are officially out of the playoff hunt. The Jets were eliminated from postseason contention on Sunday afternoon after their 32-26 overtime loss to the Miami ...
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.
Unanswered questions remain about a fatal shooting at a Madison, Wisconsin, private school as new details emerge about the shooter’s family life and possible ties to a California man who ...
