In pet genetics, if two parents have different alleles for a trait, the offspring will ___. A. inherit only one allele B. inherit both alleles C. inherit neither allele D. inherit a new allele 相关知识点: 试题来源: 解析 A。解析:在宠物遗传学中,如果两个亲本对于一个性状有不同的等位...
-Statement: "Two dominant alleles are needed to express complete dominant trait." -Evaluation: This statement isFalse. A single dominant allele (R) is sufficient to express the dominant trait, even in a heterozygous condition (Rr). 6.Evaluating Statement 4: -Statement: "F1 individuals have the...
Genetic polymorphism revealed that qHI5.1 was identical to GSE5/GW5, which is known to control the grain weight. On the other hand, although qHI8.1 functioned additively with qHI5.1 for higher HI, it did not show any significant effect on grain or panicle weight. In addition, its effects...
What is the genotype of a trait for which the two alleles an individual carries differ from each other? If you have an organism in which the A allele is dominant to the a allele, a heterozygote will produce gametes of either A or a. This is what...
Chromosomes that have the same sequence of genes and the same structure (karyotype) haploid vs diploid cells Haploid have 1 copy of each chromosome - gametes. Diploid have 2 copies of each chromosomes - somatic cells. law of segregation Mendelian law stating that two alleles for each trait sepa...
The X chromosome is hemizygous in males, but LOKI requires two alleles for all markers. We manually made the male X marker information compatible with the analysis by adding a novel allele for each X male genotype (that is, all males carried one copy of a dummy allele that was absent in...
Using an enlarged population from the same cross, a genetic map was constructed17 which enabled a QTL analysis of rootstock- induced dwarfing. In this paper, we present a multi-trait QTL ana- lysis that demonstrates that Dw1 has a major influence on the overall dwarfing phenotype. Our ...
The object of this investigation then is to determine for a disomic individual with a known pedigree, the probability that two linked autosomal loci carry genes identical by descent. At the same time other probability measures are developed. No restriction is placed on the number of alleles per...
Higher scores on the personality trait of neuroticism, the tendency to experience negative emotions, are associated with worse mental and physical health. Studies examining links between neuroticism and health typically operationalize neuroticism by summ
The co-existence of males, females and hermaphrodites, a rare mating system known as trioecy, has been considered as an evolutionarily transient state. In nematodes, androdioecy (males/hermaphrodites) as found in Caenorhabditis elegans, is thought to hav
