Mendel crossed a plant with yellow seeds (YY) with a plant with green seeds (yy). The F2 generation yielded 12 200 yellow-seeded plants and 4150 green-seeded plants. From this experiment Mendel proposed the Law of Segregation O Mutation O Independent assortment O Codominance

Which of the following is NOT one of Gregor Mendel's principles of inheritance? O principle of segregation O principle of dominance O principal of independent assortment O principle of incomplete dominance

How do you know which one number is for S/Tu or U/Tu I know both equals 36.6

In one of his experiments, Mendel crossed homozygous yellow plants with homozygous green plants. The resulting F1 generation was allowed to self-fertilize. The F2 generation produced 930 yellow seeds and 305 green seeds. What are the genotypes of this F2 generation? O YY : yy O Yy : yy O Yy: yy O YY: Yy : yy

When Mendel did crosses of true-breeding purple- and white-floweredpea plants, the white-flowered trait disappeared from the F1 generationbut reappeared in the F2 generation. Use genetic terms to explain whythat happened.

In silk moths red eyes (r) and white banded wing (w) are recessive to normal eyes (R) and 10m.u. apar normal wings (W). A moth homozygous for red eyes and white banded wings is crossed with an individual who is homozygous normal for both traits. The F, progeny are testcrossed with the following progeny produced: Normal eyes, normal wings Red eyes, normal wings 19 Normal eyes, white banded wings Red eyes, white banded wings 426 a. What phenotypic proportions would be expected if the genes for red eyes and white banded wings were located on different chromosomes? b. What is the genetic distance between these two genes? 418 16

Incomplete dominanceIn Mendel's experiments, if the gene for tall (T) plants was incompletely dominant overthe gene for short (t) plants, what would be the result of crossing two Tt plants? Explain result.

In Figure 2-19, assume that the pedigree is for mice, inwhich any chosen cross can be made. If you bred IV-1with IV-3, what is the probability that the first baby willshow the recessive phenotype?

A corn geneticist wants to obtain a corn plant that hasthe three dominant phenotypes: anthocyanin (A), longtassels (L), and dwarf plant (D). In her collection ofpure lines, the only lines that bear these alleles are AALL dd and aa ll DD. She also has the fully recessive lineaa ll dd. She decides to intercross the first two and testcross the resulting hybrid to obtain in the progeny aplant of the desired phenotype (which would have to beAa Ll Dd in this case). She knows that the three genesare linked in the order written, that the distance between the A/a and the L/l loci is 16 m.u., and that thedistance between the L/l and the D/d loci is 24 m.u.a. Draw a diagram of the chromosomes of the parents,the hybrid, and the tester.b. Draw a diagram of the crossover(s) necessary toproduce the desired genotype.c. What percentage of the testcross progeny will be ofthe phenotype that she needs?d. What assumptions did you make (if any)?
