What change in the chromosomal structure involves the transfer of one section of a chromosome to a non homologous chromosome?
The change in chromosomal structure involving the transfer of one section of a chromosome to a non-homologous chromosome is known as a chromosomal translocation. This can result in genes being positioned in a different order or location, which can potentially disrupt gene function or regulation. Translocations are associated with various genetic disorders and can have significant effects on an individual's health and development.
Differences in DNA sequence on homologous chromosomes that can result in different patterns of restriction fragment lengths?
Restriction fragment length polymorphism (RFLP)
Does meiosis have variation?
During meiosis, genetic recombination of homologous chromosomes occurs. So meiosis does result in genetic variation. After prophase I, during which crossing over occurs, every chromosome will have some maternal DNA and some paternal DNA.
What is a result if a species have homologous chromosomes?
It has pairs of matching chromosomes.
Offspring that are genetically unique are the result?
Sexual reprodution
Why does binary fission not result in genetically different organisms?
It is a form of natural cloning, both cells get identical copies of the chromosome(s).
Which process result in the formation of two genetically different cells?
Mutations result in formation of genetically different cells.

Which of these would occur as a result of independent assortment of homologous chromosomes-?
A copy of your mother's gene for a characteristic would go to a different daughter cell than the copy of your father's gene for the same chromosome.Read more: Which_of_these_would_occur_as_a_result_of_independent_assortment_of_homologous_chromosomes
What is the result of joining two genetically different mycelia in sac fungi?

How does crossing over and nondisjunction contribute to variation and increase genetic diversity in a population?
Crossing over is when two homologous chromosomes switch genes. This causes them to become different. Nondisjunction is when there is an incorrect splitting of a chromosome. These two types of variation result in a different set of genes each time an egg and a sperm collide by chance,
What are 4 types of chromosome structural changes?
The four types of alterations of chromosome structure are deletion, duplication, inversion, and reciprocal translocation. Deletion is the loss of one or more nucleotides from a gene by mutation; the loss of a fragment of a chromosome. Duplication is repition of a part of a chromosome resulting from fusion with a fragment froma homologous chromosome. Duplication can result from an error in meiosis or from mutagenesis. Inversion is a change in a chromosomeresulting from reattachment of a chromosome fragment to the original chromosome, but in a reverse direction. Mutagens and errors during mesosis can cause inversions. Translocation is the attachment of a chromosomal fragment to a nonhomologous chromosome.
After meiosis I each daughter cell contains Please explain why one chromosome of each homolog is incorrect I added my reasoning to the answer this question?
Homologous chromosomes (also called homologs or homologues) are chromosome pairs of approximately the same length, centromere position, staining pattern, with genes for the same characteristics at corresponding loci. In meiosis I, the chromosomes are duplicated first then the homologous pairs separate together. Sections of the DNA can sometimes cross over between homologous pairs. Later, during Meiosis II, these pairs are separated into the gametes with only one of each pair. If you said there was only one chromosome, you are thinking of the final result of meiosis.
