can anyone tell me the laws of Mendel and explain them?

Answer 1

Between a pair of genes (also called a pair of alleles) controlling the same trait(character if you wish) such as height, color etc, only one member is expressed in the first generation. The member, which is expressed in the first generation, is called dominant member, and the one, which is not expressed, is called the recessive member. Each member is called an allele. The allele which is expressed first is called dominant allele and the one which is not expressed first is called a recessive allele. This is called the law of dominance..
During meiosis the two alleles of a pair are separated. This is called the law of segregation.
In case of several pairs of alleles, one pair is separated independently from the other pair without any linkage. This is called the law of independent assortment.
The greatest message Mendelism has given is that genes are not contaminated in their commune and that they maintain their purity and integrity even if they associate and dissociate with others.

Answer 2

Mendel's Laws, principles of hereditary transmission of physical characteristics. They were formulated in 1865 by the Augustinian monk
Between 1856 and 1863 Mendel cultivated and tested at least 28,000 pea plants, carefully analysing the inheritance patterns of seven pairs of seed...

In human beings, and many related forms of life, inheritance occurs by a set of detailed mechanisms, some (but not all) of which are well understood. In molecular terms, heredity is due to DNA. The DNA codes for genes, and the genes specify particular proteins. The DNA acts as a set of coded instructions for building a body, given a particular environment. At a reproductive level, inheritance is a sexual process. The offspring contain two copies of each gene, inherited from their two parents. At a cellular level, inheritance proceeds via meiosis, a special kind of cell division that produces the gametes (eggs in females, sperm in males). In meiosis, the two copies of each gene are reduced to a single copy. When male and female gametes combine, the double set is restored. This pattern of heredity is called Mendelian

Answer 3

The laws put forth by Mendel are known as the LAWS OF HEREDITY.
The basic units of heredity were called by him as"FACTOR" ,i.e
what we call today "GENES".
There are three laws:

1> LAW OF DOMINANCE: Whenever any organism consists of 2 contrasting alleles of a gene,he one that expresses itself in the first generation is called dominant.The other is called Recessive.

2>LAW OF SEGREGATION: Whenever any organism,whether homozygous or heterozygous for a character forms the gametes, then the 2 alleles for the trait ,whether similar or dis similar segregate from each other ,so that each gamete receives only one member out of the two alleles of the trait.

3>LAW OF INDEPENDENT ASSORTMENT: Whenever a cross is made between 2 organisms ,which differ in 2 or more traits,then the inheritance of genes in gametes and progeny of subsequent generation is independent of each other.

Answer 4

Mendelian inheritance (or Mendelian genetics or Mendelism) is a set of primary tenets relating to the transmission of hereditary characteristics from parent organisms to their children; it underlies much of genetics. They were initially derived from the work of Gregor Mendel published in 1865 and 1866 which was "re-discovered" in 1900, and were initially very controversial. When they were integrated with the chromosome theory of inheritance by Thomas Hunt Morgan in 1915, they became the core of classical genetics.

Answer 7

if you take two organisms with dominant genes then the offspring will have that gene. he used flowers, red and white. when two recessive gene organisms have offspring then the recessive gene becomes dominant. it is usually in the 3rd generation that the recessive gene becomes dominant.
