Embodiment Construction

[0041] The following will further illustrate the present invention in conjunction with the Dazu black goat and Inner Mongolia cashmere goat (Alashan type) reference family construction of the present invention, but it is not intended to limit the present invention.

[0042] Goat resource group construction case: Dazu black goat and Inner Mongolia cashmere goat (Alxa type) reference family (DIReferenceFamily, DIRF) construction, according to the following steps:

[0043] 1. Consult the data, draw up the goat reference family construction plan, formulate the breeding record form, the basic sign information record form, the cashmere production performance record form, the meat production performance record form, the reproductive performance record form and the leather performance record form, and prepare the sample collection place Need reagent consumables, and organize relevant staff.

[0044] 2. Purchase 5 rams and 20 ewes of Dazu black goats that have no blood relationship and...

Abstract

The invention belongs to the field of establishment of a population genetic resource bank, and provides a scientific establishment method of a goat resource population bank, and provides a goat reference family system establishment case, and relates to two national-level genetic resource varieties, namely, a Dazu black goat and an Inner Mongolia Cashmere goat (Alxa type). According to the resource population establishment method, forward cross and reciprocal cross of Dazu black goat and Inner Mongolia Cashmere goat (Alxa type) are utilized, random mating of genetic relationship is avoided for F1, so that Mendel genetic characters are separated, a goat economic character QTL or a functional gene is located by virtue of a genome means, and a relatively-precise genetic mark is provided for the goat breeding. The genetic resource bank comprises goat population, a genealogy inforamtion database, a phenotypic character database, a DNA sample library, an RNA sample library and a genetic variation information database.

Description

technical field [0001] The invention relates to a method for constructing a goat resource population and the construction of an individual genome variation information database. Background technique [0002] goat( Caprahircus ), as one of the earliest domesticated livestock by humans, is widely raised all over the world, especially in developing countries such as China and India. It is estimated that by 2013, the number of goats in the world has exceeded 1 billion. Goats can provide humans with meat, wool (velvet), skin, milk, casings and other products, and are one of the foods of the Muslim people. Therefore, the healthy development of the goat industry is of great significance to improving people's level and promoting national unity. Goat breeds are the backbone to ensure the healthy development of the sheep industry, but the progress of goat genetic improvement worldwide is slow. With the completion of the Human Genome Project, the Animal Genome Project has also develo...
