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.

Which allele combination represents a female who has a heterozygous sex-linked trait?
A female with a heterozygous sex-linked trait typically has one dominant allele and one recessive allele for that trait. Since sex-linked traits are often associated with the X chromosome, the allele combination would be represented as XᴴXʰ, where Xᴴ is the X chromosome carrying the dominant allele and Xʰ is the X chromosome carrying the recessive allele. This combination indicates that the female expresses the dominant trait but is a carrier of the recessive trait.
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.
What are sections of a chromosome that are code for trait?
A section of chromosomes that codes for a trait can be called
A unit that determines that trait?
A genetic locus is the specific location on a chromosome where a particular gene is located. It serves as a unit that determines the expression of a specific trait due to the presence or absence of alleles at that locus.
True or False A mutation is the part of a chromosome that carries information about a trait?
False. A mutation refers to a change in the DNA sequence of a gene or chromosome, not the specific part of a chromosome that carries information about a trait.
What type of chromosome always carry gene for the same trait at the same location on both chromosome?
homologous chromosomes

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.
True or False A mutation is the part of a chromosome that carries information about a trait?
False. A mutation refers to a change in the DNA sequence of a gene or chromosome, not the specific part of a chromosome that carries information about a trait.
If a trait is always transmitted directly from a father to all his sons and from those sons to all their son what chromosome would the gene for the character be likely on?
The gene for this trait is likely located on the Y chromosome. The Y chromosome is passed down from father to son, and since only males have a Y chromosome, the trait will only be passed down through male lineage.
Section of a chromosome that determines a single trait?
CODON
In what chromosome is the ear lobe trait located?
The ear lobe trait is not located on a specific chromosome, as it is a common genetic trait that is not influenced by a single gene or located on a specific chromosome. The presence or absence of ear lobes is determined by multiple genetic factors.
How is chromosome involved in the inheritance of trait?
chromosomes contain DNA
Why is hemophilia considered to be a sex trait?
It is carried on the X chromosome.
