Crossing over results in recombination, which effectively cancels out linkage if it takes place between the linked genes. The closer together the two genes are, the less likely this is to occur. One percent recombination equals one MapUnit or one centiMorgan (cf. Nobel laureate Thomas Hunt Morgan) in the mapping of chromosomes. However, the virtual "distance" of genes thus gained is not necessarily directly proportional to their physical distance, as recombinant hotspots are more likely to participate in crossing over than other sites along the chromosome.
ControlThe answer will depend on the nature of the effect. IFseveral requirements are met (the effect is linear, the "errors" are independent and have the same variance across the set of values that the independent variable can take (homoscedasticity) then, and only then, a linear regression is a standard. All to often people use regression when the data do not warrant its use.
It causes the cell to split into four haploid cells.

The independent variable in this experiment is the amount of table salt added to the boiling water. The effect of adding salt to the water is to raise the boiling point of the water, therefore increasing the temperature at which the water boils.
Crossing over during meiosis can lead to the exchange of genetic material between homologous chromosomes. This can result in the formation of new combinations of alleles, which may lead to variation in the traits encoded by the genes involved in protein synthesis. Ultimately, crossing over contributes to genetic diversity within a population.
Mendel's experiments with dihybrid crossing were aimed at studying the inheritance patterns of two different traits (such as seed color and seed shape) simultaneously. By observing the outcomes of crossing pea plants with different combinations of traits, Mendel was able to establish the principles of independent assortment and gene linkage.
Law of Independent Assortment
law of dominance
Independent assortment does not happen in mitosis, it happens in meiosis. In metaphase I of meiosis, synapsed homologous chromosomes align independently of one another along the metaphase plate. That is to say, one aligning in a certain fashion has no effect on another aligning in a certain fashion. In mitosis, chromosomes are exact copies of the parental cell's and independent assortment is a method of achieving genetic variation, which does not happen in mitosis.
A backward linkage is an effect in which increased production by a downstream manufacturer provides positive pecuniary externalities to an upstream manufacturer.
It doesn't always. When crossing over occurs sections of nucleotide bases are switched. Lets take for example you have an original DNA of TTCTCCGATAGT and crossing over occurs to change this into TTCATGGATTCT. When this is now read by the mRNA only ATG will become a different protein meanwhile AGT on the original will be made into the same protein. This is because you have to look at the codon table to see which codons become which protein. Different codons may produce the same proteins so crossing over does not always ensure genetic variation but is gives genetic variation a more likely probability of happening. As for independent assortment, this doesn't lead to genetic variation. Really independent assortment will just lead to different phenotypes being expressed.
he determined three basic laws of genetic inheritance 1 law of dominance:each trait has two forms and one is shown in phenotype 2 law of segragation: each person have two alleles for a trait and the alleles do not blend rather they segragate during gamet production 3 independent assortment: each trait behaves independently meaning that which allele is segregated to which daughter cell does not effect the other alleles of different traits unless there is linkage between genes but mendel didnt know that genes coud be linked so his conclusion was made assuming that every trait's(inherited via genes)behavior was independent
The inheritance of one trait does not directly affect the inheritance of another trait, as different traits are usually controlled by different genes. However, traits located on the same chromosome may be inherited together due to genetic linkage.
Not necessarily. The independent variable may have no effect at all.

In an experiment, the independent variable is manipulated or controlled by the researcher, while the dependent variable is measured to see the effect of the independent variable. The independent variable is the cause, while the dependent variable is the effect. Changes in the independent variable are expected to cause changes in the dependent variable.
