Segregation A separation between two things or groups the alleles of the tallest and shortest plants in the First generation plants
Gamete Sex cells, sperm, egg, contains 23 chromosomes coming from each parent
Homozygous Organisms that have two identical alleles for a particular trait (TT or tt, true breeding for a particular trait)
Heterozygous Organisms that have two different alleles for the same trait heterozygous organisms are a hybrid for a particular trait
Phenotype physical characteristics, All plants have the same phenotype
Genotype Genetic makeup, All plants don't have genotype TT vs tt tallest plant
Independent assortment Genes that segregate independently they don't influence each other's inheritance
Incomplete dominance Cases in which one allele is not completely dominant over another complete dominance the heterozygous phenotype is somewhere in between the two homozygous phenotype
Co-dominance similar situation in which both alleles contribute to the phenotype
Multiple alleles Many genes have more than two alleles and are therefore said to have many alleles
Polygenic traits Traits controlled by two or more genes which means having many genes
Haploid Cells that are haploid only have one set of chromosomes it can be written n=4
Diploid A cell that contains both homologous chromosome pairs which means two sets or 2n=4
meiosis A process of reduction division in which the number of chromosomes per cell is cut in half through the separation of homologous choromosomes in a diploid cell
