What are supplementary genes?
Supplementary genes are two independent pairs of genes interacting in such a manner that one dominant factor produces its effect whether the other is present or not, while the second gene can produce its effect only in the presence of the first.
Explain why the majority of genes in an organism occur in pairs.?
Genes come in pairs because Genes are in chromosomes and chromosomes come in pairs as well.
What is inheritance determined by the interaction of two or more pairs of genes?
Polygenic inheritance.
How many pairs of genes control skin color?
3-6
Who do you get your genes from?
Your genes come from your parents. The DNA that has been passed on for generations up until your parents and then you determine which genes will be predominant (will physically appear) for example two blonde parents and two blonde grandparents mean that you will most likely be blonde.

Cumulative or cummulative?
Cumulative is the correct spelling.It is an adjective, and means: "increasing or increased in quantity, degree, or force by successive additions: the cumulative effect of two years of drought."

What is inheritance determined by the interaction of two or more pairs of genes?
Polygenic inheritance.
Does crossing over affect one or many genes?
Crossing over can effect on more then one gene i.e. at least two as in crossing over the genes of homologus chromatin get interchanged so it effect at least two genes and can effect or change more then two genes depend upon the linking and crossing over capability
How many pairs of genes control skin color?
3-6
What is the interactive nature of polygenic genes?
Polygenic inheritance occurs when one characteristic is controlled by two or more genes. Often the genes are large in quantity but small in effect. Examples of human polygenic inheritance are height, skin color, eye color and weight. Polygenes exist in other organisms, as well.
How would you describe the two ways cumulative risks occur?
Occur by the increase of effect of one risk or of each added risk

In sexual reproduction a line of genes on a DNA chain from a mother is paired with a matching chain from the father In a baby that develops from the two gene contributors the pairs of traits on its?
"In sexual reproduction, a line of genes on a DNA chain from a mother is paired with a matahing chain from the fater In a baby that develops from the two gene contributors, the pairs of traits on its DNA will?" the answer is: result from recombining traits from the mother and father
Frequency and cumulative frequency are two types of?
Tables
What is a plant that has two dominant genes or two genes called?
a homozygous
