In pea plants, the dominant S allele produces round peas and the recessive s allele produces wrinkled peas when homozygous. The dominant C allele gives yellow peas and the recessive c allele gives green peas when homozygous. The following test cross is set up between two pea plants: SsCc x sscc. 213 42 50 208 yellow Given the progeny phenotypes above, what was the arrangement of alleles in the heterozygous parent?

In sweet pea plant, an allele for purple flowers (P) is dominant when paired with a recessive allele for red flowers (p). An allele for long pollen grains (L) is dominant when paired with a recessive allele for round pollen grain (l). Bateson and Punnett crossed a plant having purple flowers/long pollen grains with one having white/flowers/round pollen grains. All F1 offspring had purple flowers and long pollen grains. Among the F2 generation, the researchers observed the following phenotypes: 296 purple flowers/long pollen grains 19 purple flowers/round pollen grains 27 red flowers/long pollen grains 85 red flowers/round pollen grains What is the best explanation for these results?
Imagine that you are performing a cross involving seed texture in garden pea plants. You cross true-breeding round and wrinkled parents to obtain F1 offspring. Which of the following experimental results in terms of numbers of plants are closest to what you expect in the F2 progeny? a. 8lOroundseeds b. 8lOwrinkledseeds c. 405:395 round seeds:wrinkled seeds d. 610:190 round seeds:wrinkled seeds
The text outlines some of the problems Frederick William I encountered in his attempt to breed tall Potsdam Guards. a. Why were the results he obtained so different from those obtained by Mendel with short and tall pea plants? b. Why were most of the children shorter than their tall parents?

In corn, the genes for tassel length (alleles T and t) andrust resistance (alleles R and r) are known to be on separate chromosomes. In the course of making routinecrosses, a breeder noticed that one T/t ; R/r plant gaveunusual results in a testcross with the double-recessivepollen parent t/t ; r/r. The results wereProgeny: T/t ; R/r 98t/ t ; r/r 104T/t ; r/r 3t/t ; R/r 5Corncobs: Only about half as many seeds as usuala. What key features of the data are different from theexpected results?b. State a concise hypothesis that explains the results.c. Show genotypes of parents and progeny.d. Draw a diagram showing the arrangement of alleleson the chromosomes.e. Explain the origin of the two classes of progenyhaving three and five members.
A cross is made between a pea plant that has constricted pods (arecessive trait; smooth is dominant) and is heterozygous for seedcolor (yellow is dominant to green) and a plant that is heterozygous for both pod texture and seed color. Construct a Punnettsquare that depicts this cross. What are the predicted outcomes ofgenotypes and phenotypes of the offspring?
Table 2 below shows the banding pattern for a cross between parents P1 and P2 producing the 6 progeny I1-6. The parents are double heterozygotes for two independently assorting genes. Identify the pairs of bands that correspond to the two segregating pairs of alleles. Assuming independent assortment, what is the probability that an offspring shows the pattern observed in I5.
