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. Be sure to put the numbers in the same order as the list phenotypes. A pure-breeding tall plant producing oval fruit is crossed to a pure-breeding short plant producing round fruit to produce the F1 generation. Tall oval, short round, tall round, short oval Submit My Answers Give Up Part B If the F1 are crossed to one another, what proportion of the F2 are expected to be short and produce round fruit? Express your answer using four decimal places. Submit My Answers Give Up

    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.

    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,...

    A variety of pure-breeding snapdragons produces a tall plant with green seeds (WWSS). A second variety of pure-breeding snapdragons produce a short plant with white seeds (wwss). The two varieties are crossed, and the resulting seeds are collected. All of the seeds are green and when planted, they produce all tall plants (WwSs). These tall F1 plants are allowed to self-fertilize. The results for seeds and plant height in the F2 generations are as follows. What is the Х 2...

    1. You want to determine whether three prairie dog genes are linked, and if so what is the order of the genes and how many map units are they away from each other. Capital letters are dominant: L = long necked, I = short-necked, G = gray fur, g = brown fur, R = red eyes, r = pink eyes. True-breeding parentals of opposite phenotypes were bred to produce the F1 hybrids, then the F1 hybrids were test crossed to...

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...

    #1. In peas, flower location and plant height are controlled by genes that follow Mendel’a law. One allele at each locus is donminat to the other at that locus: (i) AXIAL FLOWERS (A), terminal flowers (a), and (ii) TALL PLANT (T), short plant (t). A pure breeding plant for the dominant traits is mated with pure breeding plant for the recessive traits. What possible gametes can F1 individuals that interbreed make?

    You have two families of true-breeding diploid Zea mays(maize, corn) plants. Late flowering, with tall stalks Early flowering, with short stalks A cross between these two plants yields F1 hybrids that are late flowering, with tall stalks. Given this information, which alleles are dominant? Explain your reasoning. Using the letters F or f for flowering and T or t for stalk height, indicate the genotypes of the two plants. Plant 1 ______________                           Plant 2 ___________________ What is the genotype of the...
