What else can I help you with?
Do genes on the same chromosome assort independently?
No, genes on the same chromosome do not assort independently. They are often inherited together as a unit due to their physical proximity on the chromosome, a phenomenon known as genetic linkage.
What does a frequency of recombination of 50 percent indicate?
A recombination frequency is a measure of how likely it is that two genes are linked. It will also tell how likely it is that a crossing over event will occur between those two genes. Thus, for an RF=50% it is random as to whether or not the genes will be inherited together or whether crossing over will separate them (i.e. they independently assort). Traditionally, following Mendel's Second Law (that alleles of genes independently assort), an RF=50% means that the two genes are on different chromosomes; a slightly more complicated corollary is that the two genes need not be on different chromosomes but may be on the same chromosome just very far apart from each other. Thus, the smaller the RF (maximum RF is 50%), the more likely it is that two genes are linked.
Mendel's dihybrid crosses but not his monohybrid crosses show that?
genes assort independently during gamete formation.
What assorts independently during meiosis?
Genes assort independently if they are on different chromosomes. If a pair of genes are on the same chromosome, it depends on how far apart they are to determine the chances of them staying together or moving apart.
Alleles found on the same chromosomes are what?
Alleles found on the same chromosome are said to be linked. This means they tend to be inherited together and show a lower rate of recombination. Linked genes are inherited as a group and do not assort independently during meiosis.
What does NOT occur when genes are linked?
When genes are linked, they do not assort independently during meiosis. This means that they do not segregate into gametes independently of each other, which can result in different patterns of inheritance compared to unlinked genes.
Why it is chromosomes not individual genes that assort independently?
For two genes to assort independently, they must reside on different chromosomes or be located far from each other.
Do linked genes assort indepently?
no
What are the structures that actually assort independently?
Genes assort independently if they are on different chromosomes. If a pair of genes are on the same chromosome, it depends on how far apart they are to determine the chances of them staying together or moving apart.

Explain how two genes on the same chromosome can still assort independently?
Two genes on the same chromosome can still assort independently if they are far enough apart from each other. During meiosis, crossing over between homologous chromosomes can occur, leading to the exchange of genetic material between the two genes. As a result, the alleles of the two genes can recombine and assort independently during meiosis, leading to new combinations of alleles in the offspring.
Mendel's dihybrid crosses but not his monohybrid crosses show that?
genes assort independently during gamete formation.
What assorts independently during meiosis?
Genes assort independently if they are on different chromosomes. If a pair of genes are on the same chromosome, it depends on how far apart they are to determine the chances of them staying together or moving apart.
What do you know today that makes his Law of Independent Assortment not true at least in some cases?
In some cases genes are so close together (linked) normal crossing over does not occur and therefore the alleles do no assort independently.
Why do chromosomes assort independently?
Chromosomes have no direction in how they assort other than that they align in homologous pairs. The individual genes are part of the chromosomes and go wherever the chromosome goes just like the motors of cars go wherever the car goes.
Do multiple assort independently?
No they do not
