Question

80 Extensions to Mendel's Laws Chapter 3 of the gene that determines seed coat patterns s can be organized in a dominance series: 11. Alleles in lentil led > spotted- dotted (codominant alleles) > clear. A coat pattern allele was crossed to one ho the spotted pattern allele. In another cross, a hoin gous dotted lentil plant was crossed to one homozy- lentil plant homozygous for the marbled seed or mozygous f gous for clear. An Fi plant from the first cross was then mated to an Fi plant from the second cross. a. What phenotypes in what proportions are expected from this mating between the two Fi types? b. What are the expected phenotypes of the Fi plants from the two original parental crosses?

Explanation / Answer

a.½ marbled : ¼ spotted & dotted : ¼ spotted

b.Marbled phenotype from the first cross and dotted phenotype from the second cross.
