Unformatted text preview: all of the different verities; the experiments were done in a controlled setting. O Piecing It Together on p. 78 of the text describes the six major concluding principles Mendel hypothesized from his work. Describe three of them. 1. Individuals carry one of two or more forms of the DNA sequence of a particular gene . These two alleles for a given trait may be identical. This is said to be homozygous for that trait. If they differ it is said to be heterozygous for that trait. 2. Prior to reproduction, pairs of alleles are separated so that gametes contain only one allele from each pair. At fertilization, gametes fuse, contributing one allele for each trait to the new offspring. 3. Heterozygous parents are equally likely to pass either of their two alleles on to their offspring. Gametes combine at the fertilization stage not knowing to which alleles they carry. It is a matter of chance on witch individual inherits are passed on....
