Exempel på hur man kan använda GENOTYPES i en mening

• A quasispecies is a large group or "cloud" of related genotypes that exist in an environment of high mutation rate (at stationary state), where a large fraction of offspring are expected to contain one or more mutations relative to the parent.
• While the LaPerm gene is a simple dominant, the Selkirk gene (Se) acts as an incomplete dominant; incompletely dominant allele pairs produce three possible genotypes and phenotypes: heterozygous cats (Sese) may have a fuller coat that is preferred in the show ring, while homozygous cats (SeSe) may have a tighter curl and less coat volume.
• Males and females both contribute equally to the genotypes of their offspring, in which gametes fuse and form.
• With sexual reproduction, recombination scrambles alleles into different genotypes every generation; in this case, fitness values can be assigned to alleles by averaging over possible genetic backgrounds.
• Due to the continuous distribution of phenotypic values, quantitative genetics must employ many other statistical methods (such as the effect size, the mean and the variance) to link phenotypes (attributes) to genotypes.
• HEV can be clustered genetically into 8 genotypes, and genotypes 3 and 4 tend to be the ones that cause chronic hepatitis in the immunosuppressed.
• Introgressed genotypes - Studies on the blue-winged and golden-winged warbler hybrids have indicated the presence of cryptic hybridization in the past for this species.
• Frequency-dependent selection is usually the result of interactions between species (predation, parasitism, or competition), or between genotypes within species (usually competitive or symbiotic), and has been especially frequently discussed with relation to anti-predator adaptations.
• Disassortative mating is different from outbreeding, which refers to mating patterns in relation to genotypes rather than phenotypes.
• Even without genetic diversity, some genotypes have higher evolvability than others, and selection for robustness can increase the "neighborhood richness" of phenotypes that can be accessed from the same starting genotype by mutation.
• rickettsii have different genotypes and phenotypes that alter the pathogenicity, virulence, and appearance of the bacteria.
• On the other hand, a partial mole occurs when a normal egg is fertilized by one or two sperm, which then reduplicates itself, resulting in genotypes of 69,XXY (triploid) or 92,XXXY (tetraploid).
• Assortative mating (also referred to as positive assortative mating or homogamy) is a mating pattern and a form of sexual selection in which individuals with similar phenotypes or genotypes mate with one another more frequently than would be expected under a random mating pattern.
• The most commonly used commercial genotypes of vetiver are sterile, and because vetiver propagates itself by small offsets instead of underground stolons, these genotypes are noninvasive and can easily be controlled by cultivation of the soil at the boundary of the hedge.
• Nativists hold that innate beliefs are in some way genetically programmed in our mind—they are the phenotypes of certain genotypes that all humans share in common.
• Alternatively, the best genotypes can be directly propagated by cuttings or in-vitro methods and used directly in clonal plantations.
• A seed orchard is often composed of grafts (vegetative copies) of selected genotypes, but seedling seed orchards also occur mainly to combine orchard with progeny testing.
• With the advent in the mid-2000s of genotyping chips, which could measure hundreds of thousands of single-letter variations (SNPs) across the genome, deCODE statisticians were able to accurately phase segments of the genome - to understand the parental source of segments -  and then impute genotypes measured in some people across the entire population.
• As an example, consider a population of 100 four-o-'clock plants (Mirabilis jalapa) with the following genotypes:.
• Several factors affect the ability of a teratogen to contact a developing conceptus, such as the nature of the agent itself, route and degree of maternal exposure, rate of placental transfer and systemic absorption, and composition of the maternal and embryonic/fetal genotypes.
