A cross between an organism of unknown genotype and an organism that is homozygous recessive. Being closely genetically related; this type of mating can increase the likelihood of autosomal recessive disorders in the offspring. "Fraternal" twins produced ...
PATERNAL GENOTYPE INFLUENCES INCUBATION PERIOD, OFFSPRING SIZE, AND OFFSPRING SHAPE IN AN OVIPAROUS REPTILE Theoretical models for the evolution of life-history traits assume a genetic basis for a significant proportion of the phenotypic variance observed in char...

Segregation analysis of 24 families of biotinidase-deficient individuals indicated that serum biotinidase activity is determined by the segregation of a single codominant major gene with the variability about the mean of each major genotype attributable to environmental effects. Significant polygenic effects ...
The location at which a deleterious mutation arises has a marked effect on the genotype's survival prob- ability; there is a clear pattern where the probability of survival is substantially reduced both behind and in front of the region of unsuitable habitat. Although the observed pattern for ...
Hence, information sources in the index were the phenotypic observations of the daughters and the SNP genotype of the sire itself. These index sources were used to predict the aggregate genotype of the sire. Hence, the (co)variance matrix P of index sources, and again defining σam=rmg2.σ...
How to determine parental genotypes from offspring phenotypes? Explain how, by examining a pedigree, you can determine whether a trait is autosomal recessive, autosomal dominant, or sex-linked. There are gene pairs A a and B b. How can you write the genotyp...
b Transcription of insulin-1 (Ins1) by 37 primary PanNETs from RT2 AB6F2 mice was compared using Q-PCR. The tumors were also genotyped to determine the Insm1 genotype. Tumors with two Insm1 alleles from the B6 lineage are denoted “BB”, tumors from heterozygous mice are denoted “AB,...
Finally, we establish fitness consequences of genetic variation in sperm quality and its role in securing a numerical advantage in storage by showing that offspring paternity is determined strictly by the representation of stored, competing sperm. These results provide novel insight into complex post...
(P ¼ 0.068), fasting insulin (P ¼ 0.052), and steady-state glucose (P ¼ 0.065) concentrations than Suffolk ewes at the stage of pregnancy studied. As expected, transferred between-breed Suffolk lambs were born lighter (P ¼ 0.014), and transferred between-breed Cheviot lambs tended...
Total broods were counted of at least two animals of each genotype and total cell numbers in the indicated tissues of at least ten animals of each genotype. Graphs show mean±s.e.m., each dot (c,d) represents a single animal. NATURE COMMUNICATIONS | 6:5906 | DOI: 10.1038/ncomms6906 ...
