-Carried out work with Garden Peas
-Studied inheritance of characteristics
number of traits Mendel studied
Principle of Dominance
States that some alleles are dominant and others are recessive
Principles of Probability
can be used to predict the outcomes of Genetic Crosses
can be used to predict and compare the genetic variations that will result from a cross
organisms that have 2 different alleles for the same trait
Organisms that have 2 identical alleles for a particular trait
Principle of Independent Assortment
states that genes for different traits can segregate independently during the formation of gametes.
when the heterozygous phenotype is somewhere in between the 2 homozygous phenotypes.
when both alleles contribute to the phenotype
process of reproduction division in which the number of chromosomes per cell is cut in half through the speraration of homologous chromosomes in a diploid cell.
four genetically different haploid cells
two genetically identical diploid cells
