A segment of DNA on a chromosome that codes for a specific trait?
Gene. Genes come in all different lengths of nucleotides and sometimes multiple genes code for one hereditary trait, as in polygenic inheritance.
What is the difference between alleles and multiple alleles?
Alleles refer to different versions of the same gene. So a single gene can have multiple alleles. For example in fruit flies there is a single gene that controls eye color, and the eye color of the fly depends on the alleles they have for that gene (since they have two copies of every gene, being diploid). A polygenic trait refers to any inheritable trait that is controlled by multiple genes, and each of these genes can have multiple alleles. For example, eye color in humans is a polygenic trait. There are at least three different genes, each with multiple alleles, that determine eye color in humans. Polygenic traits don't follow patterns of mendelian inheritance. So in summation the difference is multiple alleles refers to different versions of one gene and polygenic traits refers to a single trait which is controlled by multiple genes (each with multiple alleles) Yes, or: Multiple alleles are "the existence of more than two alleles (versions of the gene) for a genetic traits. Polygenic traits are "[characteristics of organisms that are] influenced by several genes." So multiple alleles are more than two alleles for one trait, and polygenic traits are one trait that is influenced by multiple genes. This information came from my biology textbook, "Biology: Principles and Explorations" by Holt, Rinehart, and Winston.
Specialization form of inheritance?
Inheritance refers to the concept by which the features from one class can be extended/made available in other classes. Java supports 3 forms of inheritance * Single Inheritance * Multiple Inheritance * Multilevel Inheritance (Can be implemented using interfaces)
What is one difference between single gene trait and a polygenic trait?
Polygenic traits result in more variation because so many more alleles are involved in the process of reproduction.

What occurs when a group of gene pairs acts together to produce a single trait?
Polygenic Inheritance
What occurs when a group of gene pairs act together to produce a single trait?
Polygenic Inheritance
What is single inheritance in c plus plus?
Multiple inheritance occurs when a class is derived directly from two or more base classes. class b1 {}; class b2 {}; class d: public b1, public b2 {}; // multiple inheritance class
When a group of gene pairs act together to produce a single traits?
Polygenic Inheritance
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.
A characteristic of an organism that is determined by many genes?
The terms used to describe a number of genes on separate loci on the same chromosome (or another chromosome) which together determine a single phenotypic trait are polygene, multiple factor, multiple gene inheritance or quantitative gene.
Incomplete dominance occurs when a group of gene pairs acts together to produce a single trait?
yes that is true. the classic example is a red flower (RR) and a white flower (rr). if they produce offspring that are Rr, the offspring will be pink. R is not dominant and r is not recessive; they are incompletely dominant and combine to form a new phenotype. ^actually, that's not the right answer to the question; the answer is "NO." polygenic inheritance occurs, not incomplete dominance. incomplete inheritance? really? The answer is polygenic inheritance
How is inheritance be multiple alleles and poly genic inheritance similar?
Multiple alleles is when there are more than 2 alleles in a single trait. In blood type, instead of either one dominant and one recessive type alleles, there is one recessive allele (type O) but two dominant alleles(type A and B). Polygenic inheritance is when more than one gene controls a single trait, such as height in which three genes are responsible.
Different types of inheritances?
Single Inheritance Multiple Inheritance Multilevel Inheritance
How does polygenic inheritance differ from Mendelian inheritance?
polygenic inheritance is when more than one genes are responsible for a character/phenotype. for example human skin color. if one want to draw a pedigree for that, he will not be able to succeed. although individual genes at molecular level is inherited according to mendel's laws. and mendelian inheritance simply follows mendels laws. also the character is controlled by one gene only. for example pea plant height.
What are the advantages of multiple inheritance over single inheritance?
The advantages of multiple inheritance over single inheritance include being a realistic software model. It is useful in breaking down complicated behavior into sets of characteristics that does not interfere with one another.
What is one difference between a single gene trait and a polygenic trait?
Multiple alleles are "the existence of more than two alleles (versions of the gene) for a genetic traits. Polygenic traits are "[characteristics of organisms that are] influenced by several genes." So multiple alleles are more than two alleles for one trait, and polygenic traits are one trait that is influenced by mulitple genes. This information came from my biology textbook, "Biology: Principles and Explorations" by Holt, Rinehart, and Winston.
