What is three or more forms of a gene that code for a single trait are called?
A gene can have multiple forms, which are called Alleles. While a single gene may code for a trait in an organism, when multiple alleles exist for that gene, each different may produce a different character of that trait. For example, a person has two copies of the gene that codes for ABO blood type. There are three different alleles for this gene, A, B and O. This results in six different combinations of the alleles that the person can have (the genotype), which in turn results in four expressions of the gene in the person (called the phenotype), which is the blood type of the person.
Which of mendels principles would apply to mating two organisms that have two different alleles for three different traits?
the law of independent assorment
Which of Mendel's principles would apply to mating two oraganisms that have two different alleles for three different traits?
The principle of independent assortment
What is a polymorphic character?
" many bodies " traits. The three alleles for blood type is an example of this. Height/size is another example of this and many other variations in animal physiology are examples of this. Discrete traits, everybody has a heart, are in contrast to this, but even in discrete traits there are variations.
Is the three alleles of the single gene that controls blood type is said to be what alleles?
multiple alleles
How are multiple alleles different from polygenic traits?
Multiple alleles are genes that have more than two alleles. An example of this would be blood types, with ABO as three separate alleles.Polygenic traits are traits whose phenotype rely on alleles from different genes. An example of this would be hair type, which relies on genes from different parts of chromosomes.The main difference is that multiple alleles are genes with 3 or more alleles; polygenic traits do not necessarily have more alleles, but they rely on on multiple genes.
Polygenic traits are controlled by no more than three alleles?
No, they are controlled by only two or more traits
What three ways are human traits controlled?
Human traits are controlled by a combination of genetic factors (inherited from parents), environmental factors (such as diet and lifestyle), and epigenetic factors (changes in gene expression without changes in the underlying DNA sequence). These factors interact in complex ways to influence the development and expression of human traits.
What is the phenotype ratio for cross?
the phenotype ratio is the physical appearance
What three or more forms of a gene that code for a single trait called?
A gene can have multiple forms, which are called Alleles. While a single gene may code for a trait in an organism, when multiple alleles exist for that gene, each different may produce a different character of that trait. For example, a person has two copies of the gene that codes for ABO blood type. There are three different alleles for this gene, A, B and O. This results in six different combinations of the alleles that the person can have (the genotype), which in turn results in four expressions of the gene in the person (called the phenotype), which is the blood type of the person.
What are multiple-allele traits?
Traits governed by multiple alleles are controlled by three or more alleles, rather than two. An example in humans is the ABO blood group system. There are three alleles in the ABO blood group system, IA, IB, IO. These three alleles can produce six genotypes, AA, AO, BB, BO, AB, OO. These genotypes can produce four different phenotypes, A (genotypes AA or AO), B (genotypes BB or BO), AB, (genotype AB) and O (genotype OO).
