yes, that is how you commonly get mutts(in dogs) and other off-breeds these are examples of gene-crossing

Is it true that Gene maps are produced by monitoring the frequency of crossing-over between genes?
It is true that gene maps are produced by monitoring the frequency of the crossing-over between genes. Their changes and adaptations are use in the construction of a gene map.
Gene maps are based on?
the frequencies of crossing over between genes
How does crossing over incrase phenotypicvariation in a population?
crossing over allows new genes to be made by the crossing over itself or by mutations that occur in the genes as crossing over occurs. since the phenotype is the physical appearance of the gene, the crossing over can change the genotype which can change the phenotype.
Gene shuffling includes the independent movement of chromosomes during meiosis as well as?
Crossing-over
When gene are linked the reason a few of the recombinant genotypes still occur in the offspring is because of?
Crossing over.
How can crossing over result in gene duplication?
No, only switches traits inside the crossed over segments
Explain how crossing over can unlink genes?
crossing over can unlink genes because when crossing over occurs it a portion of one chromosome is replaced by a region of a homologous chromosome and during this the alleles that were presently on that linked gene could possibly be separated
What phase in meiosis does crossing over occur in?
Crossing over begins early in prophase I of meiosis. At the time, homologous chromosomes Are paired along their lengths. Each gene on one homologue ia alined precisely with the corresponding gene on the other homologue. Source: my science book copy right 2006
What is the relationship between crossing over and gene location?
The closer together on the chromosome that genes are more likely that they will crossover together.
During meiosis crossing-over gene exchange between chromosomes may occur Crossing-over usually results in?
The result of crossing over is genetic diversity. More specifically, it is a hybrid chromosome with a unique pattern of genetic material. Does this answer help?
Where does the crossing over during Snyapsis take place?
it takes place between homologous chromosomes and results in new gene combinations
What is a type of punnet square genetic cross that predicts the result of crossing two different alleles for the same gene?
monohybird cross
