Document Summary
O bread several varieties of plea plants and made detailed observations of their offspring. O ex: (i) tall plants with short plants, (ii) yellow with green. O (i) tallness dominated shortness (ii) green plant disappeared. But then cross seeds from first generation which produced both yellow and green pea plants in ratio. O the green trait had not been altered or lost; yellow was simply dominant, and green was recessive. O dominant: the allele of a gene pair that is always phenotypic ally expressed in the heterozygous form. O recessive: an allele phenotypic ally suppressed in the heterozygous form and expressed only in the homozygous form. O genotype: the total complement of inherited traits or genes of an organism. O phenotype: the observable physical appearance of an organism, which may or may not reflect its genotype or total genetic constitution.
