Transcript of The Work of Gregor Mendel

The Work of Gregor Mendel
Chapter 11-1

What are dominant and recessive alleles?
What is Genetics?
-the scientific study of heredity
How did Mendel study inheritance in peas?
-he studied inheritance in peas by cross-pollinating pea plants which resulted in seeds that had two different plants as parents

-he then planted the seeds and observed which characteristics the new plants would have
What was Mendel's conclusion about inheritance?
-he discovered that biological inheritance is determined by factors that are passed from one generation to the next

-he discovered "the principle of dominance" which states that some alleles are dominant and others are recessive
Dominant Alleles

a dominant allele for a particular form of a trait will always exhibit that form of the trait
Recessive Alleles

a recessive allele for a particular form of a trait will exhibit that form only when the dominant allele for that trait is not present
What happens during segregation?
-during segregation, the separation of alleles occurs during the formation of gametes or sex cells
What is fertilization?
-when male and female reproductive cells join during sexual reproduction
What is true-breeding?
-referring to Mendel's pea plants, if they were allowed to self pollinate, they would produce offspring identical to themselves
What is a trait?
-a specific characteristic, such as seed color or plant height, that varies from one individual to the next
What is a hybrid?
-the offspring of crosses between parents of a different species
What are genes and alleles?
-genes (which are found in our DNA) are chemical factors that determine traits

-alleles are the different forms of a gene, for example an allele that produces tall plants and another that produces short plants
