Define the term phenotype as used in genetics. What do the words phenotype and genotype mean? How is a phenotype determined? Which two alleles are farthest apart? What type of dominance results in a combined phenotype? What is natural selection, and does it act on genotype or phenotype?
What does HLA phenotype mean?Phenotype :Phenotypes are a set of characteristics that are observable in an individual that result from interaction with the environment. They are visible traits such as eye color, height, and blood type. Environmental factors and genetics can determine the traits....

Assortative mating, in human genetics,a form of nonrandom mating in which pair bonds are established on the basis of phenotype(observable characteristics). For example, a person may choose a mate according to religious, cultural, or ethnic preferences, professional interests, or physical traits. W...
Biology is rarely so completely neat and tidy, though.Sexual dimorphism(i.e. being able to divide a species into two sexes by their physiological characteristics) does not mean that male and female bodies are “opposites”. Rather, it’s a bit more like biological sex is on a continuum. ...
What do you mean by transgressive segregants? Transgressive segregation refers tothe phenomenon of a novel phenotype for hybrids compared to their parentsand it seems likely that many cases of transgressive phenotypes have an epigenetic basis caused by misregulated sRNAs that trigger or fail to trigge...
What does it mean for a gene to be dominant? A dominant gene is one that is expressed in the phenotype, overshadowing its recessive counterpart. 14 Can a dormant gene become dominant? Yes, a dormant gene can become dominant if environmental or genetic conditions activate its expression. 10 Ar...
allele for brown hair. Based on this information, we know that their genotype includes blonde hair and brown hair. If we observe that the individual has blonde hair – in other words, blonde hair is the expressed trait – then we know that their phenotype includes blonde hair, butnotbrown ...
In the science of genetics, the word 'phenotype' refers to the physical characteristics or traits of an organism that are observable. For example, your eye color, hair color, and the shape of your nose are all part of your phenotype. ...
What does c and p mean in genetics?IGenetics:Genetics is a branch of biology that studies our genes and heredity of an organism. A gene is a segment of DNA that is passed down from parents to offspring and confers a trait to the offspring....
