What is is a polygenetic trait?
A collection of paired genes is responsible for a polygenetic trait. Height, skin colour etc. are examples.
How many alleles does a zygote have for each trait?
No - some traits are polygenetic (such as for skin color, eye color, hair color, etc.) and will have multiple alleles.
What is polygeny?
Inheritance in which more than one gene pair affects the appearance of a particular trait. Polygenetic inheritance refers to the non-Mendelian form of inheritance in which a particular trait is produced by the interaction of many genes.
An example of a trait influenced by the environment?
tattoo skin (3rd grade epic)
What is an example of a sex-linked trait?
the color of your eyes. your skin color :D - starlight1765
Why Several genes control human eye color. Because of this eye color shows a continuous variation from very dark brown to green to blue. What is this an example of?
Eye color is not an example of polygenetic traits. Skin color is. Eye color is rather simple as far as genetics go (in humans). Brown (B) is dominate and blue (b) is recessive. A person with blue eyes has to have to have both genes for the color blue (bb). A person with brown eye color can has both genes for brown (BB) or one for brown and one for blue (Bb). The blue is not expressed in this case with Bb. Some people have hazel eyes but this is a variation of the blue color.
Skin color in humans is a simple trait and is determined by only one pair of genes or alleles true or false?
true
How many genes determine an inherited trait?
Hello there! Traits controlled by two or more genes are for example skin color and height.
What is an example of polygenetic inheritance?
Coat color and pattern is a polygenic trait, meaning it is controlled by more than one gene or gene complex. A dog with the gene for black color expression may also have the gene for suppression of black and so have a red or yellow coat. Or a dog with the brindle gene may have one or more of the genes for large areas of white and so have little or no brindle coloring visible. A dog with the dominant black gene may have genes for color fading and appear gray or merle.
What trait is a skin color?
Heredic.
Does a single pair of alleles always determine an individual trait?
No, often many other alleles will also determine the same trait. For example, many alleles put together will determine a person's skin color.
What kind of trait is present when many different genes control a single trait such as skin color?
polygenic
