What is the relationship between alleles and chromosomes?
All chromosomes consist of genes and non coding material. Animals with chromosomes arranged in the double helix pattern have two almost identical genes on the chromosomes opposite from the other. When those two genes in particular are discussed, they are called alleles. Frequently one is expressed and one is not, or one is dominant and the other is not.
What is the mechanism that breaks the linkage between linked genes?
The process of recombination during meiosis breaks the linkage between linked genes. This occurs when homologous chromosomes exchange genetic material, resulting in the shuffling of alleles between chromosomes, thereby breaking the linkage between the genes located on those chromosomes.
What is the exchange of genes between homologous pairs of chromosomes?
The exchange of genes between homologous pairs of chromosomes is called genetic recombination. This process occurs during meiosis, where corresponding segments of DNA are exchanged between maternal and paternal chromosomes, increasing genetic variation in offspring.
Genes are located on structures called what?
The structures are called chromosomes.
What are a pair of genes that are identical called?
A pair of genes that are identical are called alleles. Alleles are different forms of the same gene that occupy the same position on homologous chromosomes.

What does sex linked alleles mean?
Sex linked genes occur only on the X or the Y sex chromosomes.
How are genes chromosomes and alleles related?
Well, Alleles are a forms of genes that can be dominant or recessive,a gene is a part of a strand of DNA, and a strand of DNA is made up of genes Hope This Helped

A pair of genes that are identical are called alleles. Alleles are different forms of the same gene that occupy the same position on homologous chromosomes.
How are genes aligned on homologous chromosomes?
The genes are aligned between the pole, since it's involving homologous chromosomes, where all characteristics of chromosomes are the same, it kind of makes sense that identical genes would be aligned between the poles.
What are alleles passed from parent to child on a sex chromosomes?
They are sex-linked genes.
Why some chromosomes are recessive and the others are domainent?
Actually a chromosome consists of many genes/alleles and is neither recessive or dominant in and of itself.
How can new combinations of alleles be created when genes are linked?
New combinations of alleles can be created when genes are linked through a process called crossing over during meiosis. Crossing over occurs when homologous chromosomes exchange genetic material, resulting in the mixing of alleles between the two chromosomes. This process leads to the creation of new combinations of alleles and contributes to genetic variation in the population.
What is the relationships between chromosomes and homologous chromosomes?
Chromosomes are structures that contain genetic information, while homologous chromosomes are pairs of chromosomes that contain similar genes in the same order. Homologous chromosomes are inherited from each parent and undergo processes like crossing over during meiosis to exchange genetic material.
