- What is the study of teh branch of biology that studies heredity?
- Genetics
- What is teh Transfer of pollen from an anther to a stigma of teh same flowewr?
- Self-pollination
- What is the transfer of pollen from an anther of the flower of one plan to a stigma of the flower of another plant?
- Cross-pollination
- What means that all the offspring would display only one from of a particular trait?
- True-breeding
- What is it called when a purple-flowering plant produced only plants with purple flowers in subsequent generations?
- Parental Generation(P generation)
- Mendel then cross-pollinated two varieties from the P generation that exhibited contrasting traits, such as purple flowers and white flowers, what did he called the offspring of these plants?
- F1 generation
- When Mendel callowed the F1 generation to self-pollinate, what did he called the offspring of these plants?
- F2 generation
- (What does this mean)Having the same alleles at a particular hene locus on homologous chromosomes?
- Homozygous
- (What does this mean)Having different alleles at one or more corresponding chromosomal loci.
- Heterozygous
- (What does this mean)The combination of alleles located on homologus chromosomes that determines a trait.
- Genotype
- (Waht this mean)The expression of a sepcific trait, such as stature or blood type, based on genetic and wnvironmental influences.
- Phenotype
- Which law states that the members of each pair of allleles separate when gametes are formed?
- Law of Segregation
- Which law states that pairs of alleles separate independently of one another during gamete formation?
- Law of Independent
