3. (50) Two different pure-breeding plants were crossed and F1 gave a wild-type which was test-crossed. The following numbers were obtained for F2, focusing on three unusual characteristics: height of the plant, color of the flower, surface of fruit: 150 completely wild type; 122 small, white, rough; 571 white, rough; 603 small; 36 rough; 29 smal, white; 4 white; 5 small, rough. a. What were the genotypes of the parental lines? b. Draw a linkage map for the...

A true breeding plant for round and yellow seeds is crossed to a true breeding wrinkled and green seeds. All progeny are round and yellow seeds. A plant from the F1 is crossed to a true breeding wrinkled and green seed's plant, producing the following offspring: 32 yellow and round seeds, 36 wrinkled and green seeds, 15 yellow and wrinkled seeds and 17 green and round seeds. What is the map distance between the color gene and the size gene?...

11. Two white-flowered strains of the sweet pea (Lathyrus odoratus) were crossed producing an F1 with only purple flowers. Random crossings among the F1 produced 97 progeny plants: 54 with purple flowers and 43 with white flowers. a) What is the phenotypic ratio of the F2 generation? b) What are the probable genotypes of the parental generation? c) How would you explain biochemically the relationship between purple and white flowers?

In the tomato, three genes are linked on the same chromosome. Tall is dominant to dwarf, fruit skin that is smooth is dominant to skin that is peachy, and fruit with a normal tomato shape is dominant to oblate shape. A plant that is true-breeding for dominant traits was crossed to a dwarf plant with peachy, oblate fruit. The F1 plants were then test crossed to dwarf plants with peachy, oblate fruit. The following results are obtained. 200 tall, smooth,...

Assume a strain of flies carrying the dominant eye mutation ‘Lobe’ (L) was crossed with a strain homozygous for recessive mutations ‘smooth abdomen, straw body’ (ab, stw). All three genes are carried on the second chromosome. The F1 L females were then crossed with homozygous ab, stw males, and the following phenotypes were observed: smooth abdomen, straw body 820 ____________ Lobe 780 ____________ smooth abdomen, Lobe 42 ____________ straw body 58 ____________ smooth abdomen 148 ____________ Lobe, straw body 152...
