测试十字架

Test cross

在遗传学中,由Gregor Mendel首先引入的测试杂交涉及到具有隐性个体的主要性状个体的育种,以便通过分析具有隐性表型的后代的比例来确定前者的接合性。 后代对其每个基因的基因型由其父母遗传的等位基因决定。 等位基因的组合是由每个配子在该后代受精时产生的母体和父系染色体的结果。 在配子减数分裂期间,同源染色体经历遗传重组并随机分离到单倍体子代细胞中,每个具有母体和父亲编码基因的独特组合。 测试十字架涉及将具有相同特征的隐性版本的另一个人进行育种。 如果所有的后代都显示出显性表型,则有关个体是纯合的显性; 如果后代显示显性和隐性表型,则个体是杂合的。 In genetics, a test cross, first introduced by Gregor Mendel, involves the breeding of a dominant trait individual with a recessive individual, in order to determine the zygosity of the former by analysing proportions of offspring with the recessive phenotype. The genotype that an offspring has for each of its genes is determined by the allele inherited from its parents. The combination of alleles is a result of the maternal and paternal chromosomes contributed from each gamete at fertilization of that offspring. During meiosis in gametes, homologous chromosomes experience genetic recombination and segregate randomly into haploid daughter cells, each with a unique combination of maternally and paternally coded genes. Test crosses involve breeding the individual in question with another individual that expresses a recessive version of the same trait. If all offspring display the dominant phenotype, the individual in question is homozygous dominant; if the offspring display both dominant and recessive phenotypes, then the individual is heterozygous.

在英语 词典里testcross的定义

字典中testcross的定义是确定个体是纯合还是杂合的基因测试。

The definition of testcross in the dictionary is a genetic test for ascertaining whether an individual is homozygous or heterozygous.
