Question | Answer |
---|---|
Mendel’s Experiment | removed anthers from one plant |
Probability– | chance a trait shows up, # of events/total # of events |
Cross Pollination | plant fertilizes different plant |
Self Pollination | plant fertilizes itself |
Genes | each parent gives one set to offspring, not only influence on traits, instructions for inherited traits |
Heterozygous | one dominant and one recessive allele |
Homozygous | two dominant or recessive alleles |
Sexual Reproduction | produces offspring different than both parents |
Asexual Reproduction – | Many human body cells, mitosis, one parent |
Homologous Chromosomes | carry same set of genes |
Dominant | capital letter, showed up in first generation |
Recessive | appear in the second generation, lower case letter |
Pedigree | diagram to trace a trait |
Punnett Square | organizes different offspring possibilities, use to solve problems |
Characteristic | feature with different forms in a population |
Trait | different forms of a characteristic |
Incomplete Dominance | each allele has a degree of influence |
Allele | two forms of a gene |
Heredity | passing of traits from parent to offspring |
Genotype | organisms inherited alleles, |
Phenotype | way an organism looks |
True Breeding | always produce offspring with the same trait |
Sex Chromosomes | carry genes that determine sex, female XX, male XY, sex cells made during meiosis |
