a quantitative trait is a trait for a solution that involves numbers. such as: density, melting point or boiling point. :)
Quantitative traits refer to characteristics that are determined by multiple genes and environmental factors, resulting in a continuous range of phenotypes. These traits are typically measured on a numerical scale, such as height or weight. Quantitative genetics is the field of study that focuses on understanding the genetic basis of these complex traits.
Qualitative traits are characteristics that can be observed and categorized into distinct groups, such as eye color or blood type. Quantitative traits, on the other hand, are traits that can be measured and quantified, such as height or weight.
Weight and circumference would be 2 quantitative traits (involving numbers) and the fact that it's green and round are 2 qualitative traits (things that you observe with your senses)
Biometrical genetics is the science concerned with the inheritance of quantitative traits.
Studies in twins are more important in understanding single gene traits, as they can help determine the extent to which a trait is influenced by genetic factors. For quantitative traits, which are influenced by multiple genes and environmental factors, studies in twins may provide some insights but are generally less informative compared to other study designs such as genome-wide association studies.
Quantitative means it can be measured. Qualitative is something that is subjective meaning there is no way to really measure it. Example: Quantitative: 2=2=4 This is always true. Qualitative: Puppies are cute. (this is only an opinion. No facts)
It is indeed. Quantitative traits suggest that the traits are polygenic, which means that the trait is influenced by more than one gene and skin color is influenced by 3 genes (6 alleles). Skin color is also a multifactorial trait because there are also many environmental factors that change skin color, such as exposure to sunlight.
Nothing, quantitative and quantitative are the same thing....
It is quantitative.
Inheritance of quantitative traits or polygenic inheritance refers to the inheritance of a phenotypic characteristic that varies in degree and can be attributed to the interactions between two or more genes and their environment. Though not necessarily genes themselves, quantitative trait loci (QTLs) are stretches of DNA that are closely linked to the genes that underlie the trait in question. QTLs can be molecularly identified (for example, with PCR) to help map regions of the genome that contain genes involved in specifying a quantitative trait. This can be an early step in identifying and sequencing these genes http://en.wikipedia.org/wiki/Polygenic_inheritance
