Chromosomes that look alike and carry genes for the same trait are called homologous chromosomes. The nucleus contains these chromosomes.
What else can I help you with?
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 is a term for a gene pair dictating trait?
its a allele
If two chromosomes have the same genes for the same trait they are said to be?
Genes on the same chromosome are said to be linked
What is a section of DNA that code for a trait?
A section of chromosomes that codes for a trait can be called
What is a trait that is passed from parent to child on the X chromosome called?
Recessive traits on X chromosome are expressed in males because they have only one copy of X chromosome. If they have any recessive gene it will be expressed. In female both the genes should be recessive then only the recessive character will be expressed.
What is an organism that has genes that are alike for a particular trait called?
An organism that has genes that are alike for a particular trait is called homozygous for that trait. This means that it has two identical alleles for that specific gene.

What do you call chromosomes that have the same length and carry genes for the same trait?
It is Homologous chromosomes because they carry thesame genes and homones.
What type of chromosome always carry gene for the same trait at the same location on both chromosome?
homologous chromosomes
If two chromosomes have the same genes for the same trait they are said to be?
Genes on the same chromosome are said to be linked
What is a section of DNA that code for a trait?
A section of chromosomes that codes for a trait can be called
What part of a chromosome carries information and controls a trait?
Genes, which are segments of DNA, carry the information that controls traits on a chromosome. Each gene contains the instructions for making specific proteins that determine various characteristics or traits in an organism.
When the trait is on the X-chromosomes what is it called?
When a trait is located on the X chromosome, it is referred to as an X-linked trait. This means the trait is inherited through the X chromosome and can show different patterns of inheritance compared to traits on autosomes. Examples of X-linked traits include red-green color blindness and hemophilia.
Are recessive traits inherited?
A recessive trait can only be passed along if both parents carry at least one of the recessive genes to the child. If both parents manifest the trait (that is, if both parents have both recessive genes), then the child will manifest (that is, carry both recessive genes and display) the recessive trait. If one parent manifests and the other parent only carries the trait (that is, carries one dominant and one recessive gene) then the child will definitely carry and have a 50% chance of manifesting. If both parents carry the recessive, the child is 25% likely not to carry the trait at all, 50% likely to carry and 25% likely to manifest the trait.
If a characteristic is sex-linked then where is the gene for it found?
Genes for sex-linked traits can be found on the sex chromosomes - X and Y. Almost all sex-linked traits are determined by the X chromosome, because it is much larger than the Y chromosome and can thus carry more genes. A few sex-linked traits are known on the Y chromosome, including - believe it or not - hairy ears.
Which Chromosome has the trait For Blue Eyes?
Chromosome 19 has a blue/green gene. Chromosome 15 has a brown/blue gene. The genetics of eye color are more complex than realized previously, and more than one gene is involved in determining eye color.
