Who was Gregor Mendel and what contributions did he make?

Answer 1

Gregor Mendel (1822 to 1884) was an Austrian monk. He is often called the "father of genetics." Mendel and Walter Sutton's (an American scientist who lived from 1877 to 1916) work is related. Here is why: Mendel developed the basic laws of how traits are passed on to offspring. He did not know about genes, chromosomes, DNA, or meiosis. That's when Sutton found out that chromosomes contained genes, and had discovered Mendel's units of heredity! The laws stated below combine the work of Mendel and Sutton.

1. Individual units called genes determine an organism's traits.
2. A gene is a segment of DNA, located on the chromosomes, that carries hereditary instructions from parent to offspring.
3. For each gene, an organism typically receives one allele from each parent.
4. If an organism inherits different alleles for a trait, one allele may be dominant over the other.
5. The alleles of a gene separate from each other when sex cells are formed during meiosis.

Answer 2

Gregor Mendel was a scientist who is often dubbed the "father of genetics". He was one of the first people to study inheritance of genes through subsequent generations. He studied this in pea plants and later his work became known as Mendelian Genetics.
