Genes that come together with different alleles are called?
Genes that come together with different alleles are called linked genes. These genes are located close together on the same chromosome and tend to be inherited together during meiosis.
Linked genes are usually?
Linked genes are usually located close together on the same chromosome and tend to be inherited together during meiosis. Because of their proximity, the likelihood of recombination occurring between them is low, which can affect the genetic variation in offspring. This linkage can influence traits and is an important concept in genetics and heredity studies.
34 What is genetic linkage?
When two or more genes are so close together on the chromosome that they hardly ever cross over and are linked in the gametes where they form multiple expressions in the zygote of their linked traits.
How are crossing over and recombination related?
Genetic recombination occurs during meiosis cell division. As genes cross over during this process, scientists track the genes to study their linkage.
When crossing-over occurs what genes stay together?
Genes that are physically close together on a chromosome tend to stay together during crossing-over, while genes that are far apart are more likely to be separated. This is because crossing-over involves the exchange of genetic material between homologous chromosomes, and the likelihood of crossover is influenced by the distance between genes on the chromosome.

Do linked genes assort independently?
No, linked genes do not assort independently. Linked genes are located close together on the same chromosome and tend to be inherited together, rather than independently assorting during meiosis.
What is gene linkage?
Gene linkage is the tendency of two or more genes located on the same chromosome to be inherited together. Genes that are close together on a chromosome are less likely to be separated during the process of genetic recombination that occurs during meiosis. This phenomenon can be used to map the relative positions of genes on a chromosome.

Why does the frequency of cross-overs give information about the relative locations of genes?
The frequency of cross-overs between genes reflects the distance between them on a chromosome. Genes that are far apart are more likely to undergo a cross-over event, leading to a higher frequency of recombination. Conversely, genes that are close together are less likely to experience a cross-over, resulting in a lower frequency of recombination between them.
Are polygenic genes dominant genes?
Polygenic genes are usually dominant genes.
What is new gene combinations?
when genes cross over during meiosis, then split they from genes that differ.
How do number of chromosome affects the genes and DNA?
Not at a fundamental level, chromosomes are just the way that genes are clumped together. But on a practical level, chromosomes are what the cells manipulate during growth and (especially) during reproduction.
