INCOMPLETE DOMINANCE. All of the traits in these problems show incomplete dominance. Work these as you did the other monohybrid crosses, but interpret your results with the rules for incomplete dominance. 1. In snapdragons, flower color shows incomplete dominance. Red color is dominant to write color. What kind of offspring could result from Parent 1 being heterozygous and Parent 2 have a white flower color? Trait:

selves in the offspring. The crosses are lled ssed differently in homozy- heterozygous individuals. This produces a con- dition called incomplete dominance. In such cases, both worked out in the same manner as indicated previously, but heterozygous offspring exhibit a phenotype interme- diate between that of the homozygous individuals. Some examples follow. Activity 2 Working Out Crosses Involving Incomplete Dominance 1. The inheritance of flower color in snapdragons illustrates the principle of incomplete dominance. The geno-type RR is expressed as a red flower, Rr yields pink flowers, and rr produces white flowers. Work out the following crosses to determine the expected phenotypes and both genotypic and phenotypic percentages. % of each phenotype: 2.

TUSOIES. TITCSC CIITOTIOSOTIES are iavCicu WILT UICTEIevarIC alleles. For example: to Figure 1. Showing a homologous pair of chromosomes that carry two linked genes. Here we can see that one chromosome carries A and B alleles, while the other homologous chromosome carries a and b alleles. This is much more informative than just giving the genotype of AaBb. Another way to symbolize the arrangement of alleles on a chromosome is to give the symbols for alleles on one chromosome above a horizontal line, and the symbols for the alleles on the homologous chromosome below the horizontal line. For example: B b. Figure 2. Showing the arrangement of alleles for a pair of linked genes. Here we can see that, exactly like the example in Figure 1, one chromosome carries A and B alleles, while the other chromosome carries a and b alleles. 1. Suppose that Gene G and Gene D are linked.
