What did Gregor Mendel contribute to modern genetics?

Answer 1

Gregor Mendel : "Father of genetics" studied pea plants to explain heredity. This was before genes and chromosomes were discovered.

Why pea plants: Inexpensive, Easy to control reproduction, and produce many offsprings.

Ex: yellow or green seeds

Mendel's work: There are different versions of one gene called alleles

Began with cross pollinating( mating) pure plants with contrasting traits.

Answer 2

Gregor Mendel developed the theory of inheritance and heredity. Mendel expirimented with the garden pea plant. First he pollinated short pea plants with tall pea plants. The next generation of pea plants resulting from the expiriment were all tall pea plants. He bred two of the pea plants from thhe new generation and they ended up having 3 tall pea plants and 1 short pea plant. There seemed to be two different traits. One trait seemed to appear in every generation, this was called the dominant trait. One trait seemed to disappear; this was known as the recessive trait. Mendel discovered this, though his discoveries weren't discovered until 1900.

Many people have helped pave the pathway of genetics. Charles Darwin discovered different characteristics of finches as he sail through the galapogas islands, Punnet created the punnet square(a chart used to predict traits among offspring) and Watson&Crick discovered the structure of DNA, the hereditary information found inside the nucleus. DNa is found inside your genes which, by the thousands are found on your 23 pairs of chromosomes.

Did you know proteins, found in ribosomes determine how tall you will grow, your hair color, and many other qualities about yourself?

Mendel was important as he showed that the inheritance of certain characteristics followed certain laws. In his experiments with pea plants he showed that:

1 in 4 had two dominant Alleles ('flavours' of a gene)

2 in 4 had a dominant and a recessive allele

1 in 4 had two recessive alleles

In short he proposed a mechanism for how inheritance worked

Answer 3

Gregor Mendel's contribution to modern genetics is huge as he is considered the father of genetics. He actually described the two laws of genetics including segregation and independent assortment.

Answer 4

Mendel's studies formed the basis of what we now called genetics. Before then, the theories were that traits were blended. That meant that if a dark hair person had children with a blond haired person , the children would have something in between.
But with Mendel's work with pea plants several rules were formed. These rules took time to take hold.
There are three main ones: 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).

Answer 5

Using pea plants, Mendel was able to prove that traits of different organisms were passed through generations by alleles.

Answer 6

Gregor Mendel contributed to the foundation of modern genetics by discovering some basic principles of heredity.
