Dihybrid Cross Problem 10: Exceptions to the 9:3:3:1 ratio of offspring? If Mendel's crosses between tall, spherical-seeded plants and short, dented- seeded plants had produced many more than 1/16 short, dented-seeded plants in the F2 generation, he might have concluded that: A. the dented seed and short traits are unlinked. B. he would not have concluded any of the above. C. all traits in peas assort independently of each other. D. the spherical seed and tall traits are linked. E. all traits in peas are linked.

Punnett Square Problems a. The presence of a widow's peak is dominant over a straight hairline. In a cross between a homozygous dominant male and a homozygous recessive female, what is the male's genotype? Use the letter T and/or t in showing the correct genotype. b. What are the resulting genotype(s) of the offsprings in the cross from the previous question? If you are including multiple answers, separate them with commas. c. What is the resulting phenotype(s) of the offspring? If you are writing multiple answers, please separate them with commas.

Question:- A farmer decides to cross two tomato plants. One of the plants is a dihybrid for genes G and H. The other is homozygous recessive for gene G but homozygous dominant for gene H. Which of the following offspring genotypes would be recombinants? Select all that apply. Select one or more: a. GgHH b. All of the above are recombinant c. ggHH d. None of the above are recombinant e. ggHh f. GgHh

17. Please solve and make sure all relevant calculations of m.u. take into consideration double crossovers!

Problem 1: The data in the table below show the results of the F2 generation for 7 of Mendel's crosses: P (FO) Cross F1 Generation Tall x short stem. Purple x white flowers Axial x terminal flowers Yellow x green seeds Round x wrinkled seeds Green x yellow pods Smooth x wrinkled pods Total 100% tall 100% purple 100% axial 100% yellow 100% round F2 Generation 100% green 100% smooth 100% dominant 787 tall, 277 short 705 purple, 224 white 651 axial, 207 terminal 6022 yellow, 2001 green 5474 round, 1850 wrinkled 428 green, 152 yellow 882 smooth, 299 wrinkled 14949 dominant, 5010 recessive Conduct a X² analysis to determine if these data are consistent with Mendel's law of segregation.

Practice with Crosses. Show all work! 6. A TT (tall) plant is crossed with a tt (short plant). a. What percentage of the offspring will be tall? 7. A Tt plant is crossed with a Tt plant. a. What percentage of the offspring will be short? 8. A heterozygous round seeded plant (Rr) is crossed with a homozygous round seeded plant (RR). a. What percentage of the offspring will be homozygous (RR)? 9. A homozygous round seeded plant is crossed with a homozygous wrinkled seeded plant. a. What percentage of the offspring will also be homozygous?
