Mendel's First Law = the law of segregation If you have freckles (FF), then your gametes must have a freckle allele (F); if you have no freckles (ff) then your gametes must have a a non-freckle allele(f) or you might have one allele of each kind (Ff), in which case you make two kinds of gametes some contain thefreckle allele (F) and some contain the non freckle allele (f). therefore, if you have freckles= FF OR Ff because of dominant trait, the capital F. if you have no freckles= ff Mendel's Second Law = the law of independent assortment. first parent= AABB 2nd parent= aabb you would therefore inherit AB and ab = ABab(your genotype) OR if for another example, first parent= AaBb 2nd parent= AAbb you would inherit ABAb or AbAb or aBAb or abAb, a 1/4th inheritance.
Mendel studied sweet peas. And the first person to put heredity to the test was Gregor Mendel,
who systematically tracked dominant and recessive traits in his famous pea plants. Mendel published his work on the statistics of genetic dominance in 1866 to little notice.
But his studies did cause other scientists to arrange what they saw into what they then called
The Law of Segregation, the Law of Independent Assortment, and the Law of Dominance.
1)The law of Segregation states that the two alleles (genes) for a heritable character segregate (separate from each other) during gamete (egg or sperm) formation and end up in different gametes.
2) In the Law of Independent Assortment, the chromosomes that result are randomly sorted from all possible combinations of maternal and paternal chromosomes: 2 to the 23rd power
3) Law of Dominance states that recessive alleles will always be masked by dominant alleles. (In general).
It is the study of genes and chromosomes which are present in cells and behave as heriditary material to the next generations

Why Mendelian laws are not applicable in crossing over.
Linkage
Yes, both Mendelian and non-Mendelian laws are applicable to prokaryotes. Mendelian laws, such as the law of segregation and the law of independent assortment, describe the inheritance patterns of genes in prokaryotes similarly to how they do in eukaryotes. Non-Mendelian laws, such as incomplete dominance or co-dominance, can also be observed in prokaryotes. However, it is important to note that prokaryotes have different mechanisms of gene transfer, such as horizontal gene transfer, which can give rise to non-Mendelian inheritance patterns.
Linkage
A trait with no clearly dominant allele.
Evolution in Mendelian Populations was created in 1931.
Why Mendelian laws are not applicable in crossing over.
In Mendelian inheritance the allele has a one to one effect on the phenotype. A polygenic effect is given when many genes contribute in an additive fashion to the phenotype. Height is such and may have as many as eight genes contributing to the effect. Behavior is also of this type. Eye color is more Mendelian in nature.

Mendelian refers to the principles of genetics developed by Gregor Mendel in the 19th century. Mendelian genetics focuses on the inheritance of traits from parents to offspring through the passing of alleles. Mendel's work laid the foundation for the study of genetics.
pleiotropic
A trait controlled by many genes
A trait with no clearly dominant allele.
