Mendelian Genetics Study Guide with
Complete Solutions (Graded A+)
Genetics - ✔️✔️The scientific study of heredity
Fertilization - ✔️✔️When male and female reproductive cells join during sexual reproduction
True-breeding - ✔️✔️If they were allowed to self-pollinate, they would produce offspring identical
to themselves (always homozygous)
Cross-breeding - ✔️✔️When offspring has two different parents
Trait - ✔️✔️specific characteristic that varies from one individual to another
Genes - ✔️✔️Chemical factors that determine traits
Allele - ✔️✔️Different forms of a gene
Principle of Dominance - ✔️✔️States that some alleles are dominant, and others are recessive
Dominant allele - ✔️✔️An allele whose trait always shows up in the organism when the allele is
present.
Recessive allele - ✔️✔️An allele that is masked when a dominant allele is present
Gamete - ✔️✔️sex cell; an egg or a sperm cell
Punnett Square - ✔️✔️Diagram that can be used to predict what genetic variations that would
result from a cross
*Know how to do a 1 trait cross & a 2 trait cross Punnett Square*
Independent Assortment - ✔️✔️The random distribution of the pairs of genes on different
chromosomes to the gametes
Homozygous - ✔️✔️Organisms that have two identical alleles for a particular trait
Heterozygous - ✔️✔️Organisms that have two different alleles for a particular trait
Phenotype - ✔️✔️Physical characteristics of an individual
Genotype - ✔️✔️Genetic makeup of an individual
