The second is “Black pied with white marks on head”, representing Asian breeds like the Vietnamese native Mong Cai. The third pattern variant is a “White belt” on a black background, most represented by the British breeds of Essex and Wessex. In general, many breeds show different ...
Tuta absoluta; resistance inheritance; cross-resistance; autosomal; incomplete recessive; flubendiamide1. Introduction Tomato pinworm, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), is endemic to tropical and subtropical regions of the Americas [1,2,3]. From its Peruvian origin [4], this ...
Two genetic forms of the disease have been described: one transmitted as an autosomal dominant trait, caused by mutations in the gene encoding the ryanodine receptor type 2 (RyR2), and another very rare form due to recessive mutations in the cardiac-specific isoform of the calsequestrin gene, ...
If the risk allele of a polymorphism shows a recessive effect, frequencies of respectively: the risk genotypes of a sibling and an offspring, YS1 and YO1, are represented as follows, YS1 = (p + u)2/4 (8) YO1 = pu (9) In the recessive model, homozygote is the risk genotype. ...
In the present paper we prove that this indeed opens the possibility\nthat individuals with a pure genotype can reinvade in the population after the\nappearance of further mutations. We thus expose a formal description of a\nmechanism by which a recessive allele can re-emerge in a population...
A forward primer, used in combination with a reverse primer located in the deleted sequence, yields product only from the normal allele because the reverse priming site is missing from the mutant allele. The same forward primer, used in combination with a reverse primer located across the break...
Sclerosteosis is an autosomal recessive sclerosing bone dysplasia characterized by progressive skeletal overgrowth. The majority of affected individuals have been reported in the Afrikaner population of South Africa, where a high incidence of the disorder occurs as a result of a founder effect. ...
In conclusion, srg1 was a new allele of BC12 gene, which could control the mechanical strength in a different way. The expression pattern of SRG1 displayed different expression levels during the panicle and grain development, implying that the expression of SRG1 was spatiotemporal. It is known...
IR64, released in the Philippines in 1985, represented a breakthrough in combining excellent palatability of cooked rice with the other traits found in previous IRRI HYVs. IR64 replaced IR36 in most growing areas and spread rapidly in new areas. Because of its wide adaptation, early maturity,...
Based on its allelic combination, a gene can be classified into one of three groups. These groups are: heterozygous (one dominant and one recessive allele), homozygous dominant (two dominant alleles), and homozygous recessive (two recessive alleles)....
