What is the relationship between a gene and an allele?
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.
Which is not a characteristic of homologous chromosomes?
Homologous chromosomes do not have identical DNA sequences; while they carry the same genes, the alleles (variations of those genes) can differ between the chromosomes. Additionally, homologous chromosomes can vary in size, shape, and genetic content due to the presence of different alleles and possible structural differences. Thus, the key characteristic that is not true for homologous chromosomes is that they are not identical in sequence.
Does cytokinesis provide new genetic combinations?
Yes. Crossing over (or recombination) shuffles sequences between homologous chromosomes. The resulting chromosomes have different combinations of alleles from the original chromosomes.
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 genetic relationship between generations?
Each new generation inherits alleles from the previous generation.

What is the relationship between pair of alleles in genetic inheritance?
In genetic inheritance, a pair of alleles refers to the two forms of a gene that an individual inherits from their parents. These alleles can be either the same (homozygous) or different (heterozygous). The relationship between a pair of alleles determines how they interact to determine the traits or characteristics of an individual. This interaction is known as Mendelian genetics, where dominant alleles mask the effects of recessive alleles.
Which is not a characteristic of homologous chromosomes?
Homologous chromosomes do not have identical DNA sequences; while they carry the same genes, the alleles (variations of those genes) can differ between the chromosomes. Additionally, homologous chromosomes can vary in size, shape, and genetic content due to the presence of different alleles and possible structural differences. Thus, the key characteristic that is not true for homologous chromosomes is that they are not identical in sequence.
Which of the pairs has a relationship that is most similar to the relationship between genes and chromosomes?

What is the relationship between protein and chromosomes?
The mRNA is transcribed into proteins
Organisms that have identical alleles for a particular trait are called?
There is no particular relationship between organisms that have identical alleles for a particular trait.
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 best describes the relationship between chromosomes and DNA molecules?
