What do alleles determine?
Alleles are different forms of a gene that can code for different traits. They determine variations in specific characteristics such as eye color, height, or blood type. Each individual inherits two alleles for each gene, one from each parent.
What role does an allele play in determining an organism's traits?
An allele is a variant form of a gene that can influence an organism's traits. Organisms inherit alleles from their parents, and the combination of alleles they have can determine their physical characteristics, such as eye color or height. The specific alleles present in an organism's genetic makeup can impact how traits are expressed.
What are Mendel's factors?
Mendel's factors, now known as genes, are units of heredity that control specific traits in organisms. They are passed from parents to offspring and determine characteristics like eye color, height, and blood type. Genes are made up of DNA and are located on chromosomes in the cell.
Characteristics such as hair color and height are called?
Characteristics such as hair color and height are called phenotypes. Phenotypes are determined by the make up of alleles in the body, known as genotypes.
Different forms a gene may have for a traits?
They are called alleles. Alleles determine things such as your eyecolor, height, fingerprints, etc.

An example of a trait that is determine by multiple alleles is?
Human height , sin color ,intelligence e.t.c.
What is a physical appearance of an individual is determined by the alleles that code for traits?
Physical appearance is determined by the combination of alleles inherited from parents, which code for traits such as eye color, hair color, and height. These alleles interact in complex ways to produce a diverse range of physical characteristics in individuals. The expression of these traits can also be influenced by environmental factors.
How dominant or recessive alleles for the trait of stem height determine whether a pea plant will be tall or short?
The dominant trait for height in a pea plant is tall (TT or Tt). The only instance in which a pea plant will be short is if it carries both recessive alleles (tt).
How do you know that human height is not multiple alleles?
It is based on multiple alleles.
What do alleles determine?
Alleles are different forms of a gene that can code for different traits. They determine variations in specific characteristics such as eye color, height, or blood type. Each individual inherits two alleles for each gene, one from each parent.
How are traits inherited by an individual can be determined by one pair of genes?
alleles.
The different forms of a gene for a specific trait such as height?
The different forms of a gene for a specific trait, such as height, are called alleles. These alleles can vary in terms of their specific DNA sequences, ultimately resulting in different phenotypic expressions of the trait. For example, in the case of height, an individual may inherit alleles for tall or short height from their parents, leading to variation in their own height.
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 role does an allele play in determining an organism's traits?
An allele is a variant form of a gene that can influence an organism's traits. Organisms inherit alleles from their parents, and the combination of alleles they have can determine their physical characteristics, such as eye color or height. The specific alleles present in an organism's genetic makeup can impact how traits are expressed.
Can parents' genes necessarily determine height of child?
No, a child's height is determined by a combination of genes from both parents as well as environmental factors like nutrition and health care. While genes play a significant role in determining height, they are not the sole factor influencing it.
