What is interspecific hybridization give an example in plants?

Interspecific Plant Hybrids Tangelo – It is a hybrid between two citrus genus. A citrus fruit like orange is crossed with grapefruit or pomelo. Limequat – A hybrid variety from the crossing of key lime and kumquat. Jostaberry – It is a complex hybrid involving three different species of the same genus.

Which of the following would be an advantage of interspecific hybridization?

The main advantage of this type of breeding is that progeny/ offsprings are produced which have the desirable features of both the species i.e the new individual produced is superior to the existing ones. Example − Mule is an interspecific hybrid of donkey and horse. The mule is superior than both donkey and horse.

What is vegetable hybridization?

Each variety of vegetables began as a hybrid, with a cross between two different plants by free pollination. This explains the immense diversity of varieties in the vegetable world.

Why interspecific hybrids are sterile?

Mules, hinnies, and other normally sterile interspecific hybrids cannot produce viable gametes, because differences in chromosome structure prevent appropriate pairing and segregation during meiosis, meiosis is disrupted, and viable sperm and eggs are not formed.

Is Mule an interspecific hybridisation?

A mule is produced by the interspecific hybridisation between male donkey and a female horse (mare). In interspecific hybridisation, male and female animals of two different related species are mated.

What are the problems associated with hybridization?

The harmful effects of hybridization, with or without introgression, have led to the extinction of many populations and species in many plant and animal taxa 3. Hybridization is especially problematic for rare species that come into contact with other species that are more abundant.

Is Hinny an interspecific?

Mule is formed from interspecific hybridisation between a male donkey and a female horse whereas hinny is formed from interspecific hybridisation between a female donkey and a male horse.

Is mule an interspecific hybridisation?

What are the types of hybridization?

The five basic shapes of hybridization are linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral.

How is hybridization used in agriculture?

Hybridization is growing two plants together in a special way to help the plants develop the natural traits we like. Hybridization differs from Genetically Modified Organisms (GMOs) because hybridization takes advantage of traits natural to the plant, where GMOs insert traits that are not natural to the plant.

Are interspecific hybrids fertile?

Interspecies hybrids often show some advantages over parents but also frequently suffer from reduced fertility, which can sometimes be overcome through sexual reproduction that sorts out genetic incompatibilities.

What problems do hybrids face?

One of the main obstacles is that, even if members of different species might mate, when the two species are too distant genetically or carry different numbers of chromosomes, the offspring are usually inviable or infertile (like zorses and mules), and are therefore evolutionary dead ends.

What are intraspecific hybrid crops?

These types of hybrids are commonly used for commercial cultivation in several cross pollinated crops and some self-pollinated crops. Intraspecific hybrids are always fertile.

How are interspecific and intergeneric hybridization performed?

To produce potential new cultivars, interspecific and intergeneric hybridizations have been performed between cultivated species and between cultivated species and their wild relatives. Furthermore, interspecific and intergeneric hybrids have been successfully produced using embryo rescue techniques.

What are the two types of hybrid plants?

The commercially cultivated hybrids are of two types, viz.: (2) Interspecific hybrids. Type # 1. Intraspecific Hybrid: A hybrid between genetically different genotypes of the same species is known as intraspecific hybrid. It is also known as inter-varietal hybrid.

What is inter-varietal hybrid?

It is also known as inter-varietal hybrid. These types of hybrids are commonly used for commercial cultivation in several cross pollinated crops and some self-pollinated crops. Intraspecific hybrids are always fertile.
