In soybeans, dwarf (D) is dominant to tall (d), round (R) is dominant to oval (r), and green (G) is dominant to brown (g). The genes are linked and the map is given below. Pure-breeding tall, round, green plants were mated to pure-breeding dwarf, oval, brown plants. The F1 were testcrossed. All loci are autosomal. The coefficient of coincidence is 1. Height Shape Color 14cM 22cM Rank the progeny phenotypes below to indicate their frequency in the testcross progeny based...

plz help rating will follow!
In tomatoes, tall (D) is dominant over dwarf (d) and smooth fruit (P) is dominant over pubescent fruit (p), which is covered with fine hairs. A farmer has two tall and smooth tomato plants, which we will call plant A and plant B. The farmer crosses plants A and B with the same dwarf and pubescent plant and obtains the following numbers of progeny: Dd Pp Dd pp dd Pp Progeny of Plant A Progeny...

A mutant dwarf tomato plant with yellow fruit is self-fertilized and the following progeny are produced: Normal size, yellow fruit: 39 plants Normal size, red fruit: 13 plants Dwarf, yellow: 111 plants Dwarf, red : 35 plants a. What are the phenotypes, alleles, and possible genotypes for the two traits? For the alleles designations, you must use the common convention for assigning alleles for plants, includes symbols consistent with how alleles interact. b. What is the most likely genotype of...

Item 15 Part A In a diploid species of plant, the genes for plant height and fruit shape are syntenic and separated by 18mu. Allele D produces tall plants and is dominant to d for short plants, and allele R produces round fruit and is dominant to r for oval fruit. If the Fi are crossed to short plants producing oval fruit, what are the expected percentages of progeny phenotypes? Express your answers using two significant figures separated by commas....

12. In snapdragons, the allele for tall plants is dominant to the allele for dwarf plants , and t he allele for red flowers is codominant with the allele for white flowers . The heterozygous condition for flower color is pink. Question – If a dwarf red snapdragon is crossed with a white snapdragon homozygous for tall, what are the probable genotypes and phenotypes of the F1 generation? a. tall and pink b. tall and red c. tall and white...

You are studying three linked genes in snapdragons. The flower color locus is in the center. There are 12.7 cM between the flower color locus and the plant height locus. There are 11.5 cM between the flower color locus and the leaf type locus. The coefficient of coincidence is 0.8. Pure-breeding tall, red-flowered plants with fuzzy leaves were crossed to pure-breeding dwarf, blue-flowered plants with smooth leaves. The F1 were testcrossed. Calculate the proportion of the testcross progeny that are...

. A tomato plant homozygous for tall stature and oblong fruit is pollenated by a plant that is homozygous for dwarf stature and normal-shaped fruit. Note that these genes belong to one linkage group. (See Ex. III, Part A. traits list) 24. What are the genotypes of the parents? tall/oblong – Dwarf/normal 25. What alleles will the sperm carry? What alleles will the eggs carry? 26. What are the...

a) In radishes, the plants can be tall (allele T) or dwarf (allele t). Tall is dominant. Root color can be red (allele RR), white (allele RW), or pink (heterozygote). A radish that is true-breeding for both red roots and tallness (RRRR TT) is crossed with a radish that is true-breeding for both white roots and being dwarf (RWRW tt). Write the genotype and phenotype for the F1 generation. b) Assume the two genes for plant height and root color are...

9. In tomato plants, the tall allele (T) is dominant to the short allele (t) for height. In addition, the allele for red fruit (R) is dominant to the allele for yellow fruit (r). Please show the cross between the following two plants (one tall, red and the other tall, yellow). TTRR X Tter 3 a. What is the genotypic ratio of the offspring? 6:2 b. Can you get any tall, yellow plants (that look like the one parent) from...

A tomato plant heterozygous for stem color and fasciation (the dominant alleles linked on the same chromosome) is pollinated by a plant heterozygous for stem color and homozygous recessive for fasciation (that is nonfasciated). 29. What alleles will the sperm carry?_ What alleles will the eggs carry? 30. What are the genotypes of the progeny? What are the phenotypes of the progeny? 31. If the dominant alleles for stem color and fasciation are commonly located on the same chromosome, how...
