What is the distinct location on a chromosome that represents a trait?
The distinct location on a chromosome that represents a trait is known as a gene. Each gene occupies a specific position, or locus, on a chromosome and encodes the information necessary for producing proteins that influence various traits. Variations in these genes, called alleles, can lead to different expressions of a trait within a population.
Where a chromosome is found?
In the nucleus of each cell in the body.
Where genes for a certain trait are located?
Genes for a certain trait are located on specific regions of chromosomes. Each gene occupies a particular locus on a chromosome, and variations in these genes can result in different expressions of the trait. The specific location of a gene on a chromosome is referred to as its genetic map position.
Did Mendel find all the 7 traits on 7 different chromosome?
Gregor Mendel studied seven different traits in pea plants, but these traits were not necessarily found on seven distinct chromosomes. Instead, each trait is controlled by genes located on different chromosomes, and the principles of Mendelian genetics apply to the inheritance of these traits independently of their chromosomal location.
Why are X linked traits more common in mals then in females?
This is because males have one X chromosome while females have two. Example: Say a mother is homozygous for a certain recessive X-linked trait (ie x*x*) while the father does not have this x-linked trait (XY) If they have one boy and one girl: The girl will receive an x chromosome from each parent, and will be x*x: this means she will be a carrier only, and will not display this recessive trait. The boy will receive an x chromosome from his mom and a y chromosome from his dad, so he will have to be x*y. The boy will always display the trait. It works similarly if the mother is a carrier(ie x*x): the boy is more likely to display the trait because he gets only one x chromosome.
How many copies of each chromosome are found in animals sex cells?
1
How many copies of each chromosome are found animal sex cells?
1
How many chromosome 7 s are there in the human nucleus?
Two, one from each parent. Over 90,000 genes are found on each chromosome and are mostly responsible for protein productions.
What is name of the two genes one on each chromosome of a pair that control the same trait are called?
They are called alleles. Each allele is a different form of the gene, and they can be dominant or recessive.
Is down syndrome homozygous or heterozygous?
Diabetes mellitus is represented by 'D' for dominant trait i.e. person is normal or not suffering from diabetes.Diabetes mellitus is a homozygous recessive trait i.e. 'dd'. A person having this trait will suffer from diabetes.
What is a chemical found within each chromosome?
DNA (deoxyribonucleic acid) is the chemical found within each chromosome. It is a molecule that carries the genetic instructions for the development, functioning, growth, and reproduction of all known living organisms.
Are all traits of an organism found in its gene?
yes each gene has 100 chromosome on it
