What kind of genetics does Gregor Mendel study?
Mendelian genetics, also known as classical genetics, is the study of the transmission of inherited characteristics from parent to offspring. Gregor Mendel actually calculated the ratios of observable characteristics in the common garden pea plant Pisum sativum.
How many genes are there in the human genome?
The Human Genome Project has estimated that humans have between 20,000 and 25,000 genes. Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people.
What kind of information does a gene carry?
Genes carry information that determines the traits, the characteristics we inherit from our parents. The branch of biology that deals with heredity, especially the mechanisms of hereditary transmission and the variation of inherited characteristics among similar or related organisms is known as genetics.
How is a recessive gene different from a dominant gene?
Conversely, if the allele could only be detected in the minority of the offspring of hybrid parents that were homozygous for that “weaker” allele, the gene is termed a “recessive”. Dominant and recessive are relative terms. Consider a plant with a gene for red flower colour and a gene for blue flower colour.
