Which occurrence is when an individual inherits a dominant gene but does not fully express the dominant phenotype?

Incomplete penetrance


If two different alleles for a trait are present and one allele doesn't entirely block the expression of the other What is the genetic situation called?

Then they are codominent and a little bit of each will show up in the organism's phenotype.


When an organism has two recessive coloring genes which color does it exhibit?

Well, if you're talking about mendelian inheritance, one will always be recessive to the other. But in real life, there are a lot of other factors like x-inactivation and incomplete penetrance, codominance, icomplete dominance, etc to think about. So if it's a gene where codominance or incomplete dominance is possible, then you may see the appearance of BOTH traits (codominance) or a BLENDING of the traits (incomplete dominance). X-Inactivation and incomplete penetrance are more difficult to predict because you really just have to see the offspring to see what happened. Sorry if that was confusing, hope that helps!


Why is there such a difference between the number of individuls who carry the allele and the number actually born with disease?

The discrepancy between the number of individuals carrying a disease allele and those actually born with the disease can be attributed to several factors, including incomplete penetrance and variable expressivity. Incomplete penetrance means that not everyone with the allele will express the disease phenotype, while variable expressivity refers to the range of symptoms and severity that can occur among those who do express the condition. Additionally, environmental factors and interactions with other genes can influence whether an individual with the allele develops the disease. These factors contribute to a lower observed prevalence of the disease compared to the number of carriers.


How penetrance and expressivity can affect phenotypes?

Penetrance refers to the proportion of individuals with a specific genotype that actually express the associated phenotype, while expressivity describes the variation in phenotype expression among individuals with the same genotype. High penetrance means most individuals with the genotype show the phenotype, whereas low penetrance results in some individuals not expressing it at all. Expressivity affects how intensely or in what form a phenotype appears, leading to a spectrum of manifestations even among those with the same genetic background. Together, these factors can lead to diverse phenotypic outcomes in a population, complicating the prediction of traits based on genotypes alone.
