What else can I help you with?
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 gene does a human have?
Humans typically have about 23,000 genes, organized into 23 pairs of chromosomes. Each pair consists of one chromosome inherited from each parent, resulting in a total of 46 chromosomes. Thus, in terms of gene pairs, humans have approximately 23,000 pairs of genes, with each gene generally existing in two copies (one from each parent).
What is the minimum number of genes involved in epistasis?
The minimum number of genes involved in epistasis is two. Epistasis occurs when the effect of one gene masks or modifies the effect of another gene at a different locus.
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 are supplementary genes?

Polygenic inheritance.
How would you describe the two ways cumulative risks occur?
Occur by the increase of effect of one risk or of each added risk

Thus, in terms of gene pairs, humans have approximately 23,000 pairs of genes, with each gene generally existing in two copies (one from each parent).
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
What is the minimum number of genes involved in epistasis?
The minimum number of genes involved in epistasis is two. Epistasis occurs when the effect of one gene masks or modifies the effect of another gene at a different locus.
How many gene pairs contribute to the wheat grain colour?
Wheat grain color is primarily influenced by a small number of gene pairs, particularly two major genes: the P gene and the C gene, which determine whether the grain is red or white. Additionally, several minor genes also contribute to the variation in color. Overall, while the primary genes are few, the total number of gene pairs involved in determining wheat grain color can be more extensive due to the influence of these minor genes and their interactions.
Organisms inherit genes in pairs from each what?
Organisms inherit genes in pairs from each parent during sexual reproduction. Each parent contributes one set of genes, forming pairs that determine the genetic makeup of the offspring. This process ensures genetic variation and diversity in offspring.
Traits are determined by pairs of genes called?
The two chromosomes (two "X" shapes) that are in a pair are generally called "homologous chromosomes". A pair of "chromatids" make up the two arms of a single chromosome.
Height and skin color are determined by two or more genes. They are known as?
Height and skin color are determined by multiple genes and are referred to as polygenic traits. These traits result from the cumulative effects of several genes, each contributing to the overall phenotype. This genetic complexity leads to a wide range of variations in height and skin color within populations.
