A pea plant is heterozygous for three genes (Tt Rr Yy), whereT = tall, t = dwarf, R = round seeds, r = wrinkled seeds, Y = yellowseeds, and y = green seeds. Tall, round, and yellow are the dominanttraits. What is the probability that an offspring from self-fertilizationof this plant will be tall with wrinkled, yellow seeds?
A cross between two pea plants, both of which grewfrom yellow round seeds, gave the following numbersof seeds: 156 yellow round and 54 yellow wrinkled.What are the genotypes of the parent plants? (Yellowand round are dominant traits.)
Most of the feathers of erminette fowl are light colored, with an occasional black one, giving a fleckedappearance. A cross of two erminettes produced a totalof 48 progeny, consisting of 22 erminettes, 14 blacks,and 12 pure whites. What genetic basis of the erminette pattern is suggested? How would you test yourhypotheses?
On rare occasions, an organism may have three copies of achromosome and therefore has three copies of the genes on thatchromosome (instead of the usual number of two copies). Forsuch a rare organism, the alleles for each gene usually segregateso that a gamete will contain one or two copies of the gene. Let’ssuppose that a rare pea plant has three copies of the chromosomethat carries the height gene. Its genotype is TTt. The plant is alsoheterozygous for the seed color gene, Yy, which is found on adifferent chromosome. With regard to both genes, how manytypes of gametes can this plant make, and in what proportions?(Assume that it is equally likely that a gamete will contain oneor two copies of the height gene.)
Pea plants with purple pollen and long-shaped pollen were crossed with each other withthe following offspring: 296 purple long-shaped pollen; 19 with purple round-shapedpollen; 27 with red long-shaped pollen; 85 with red round-shaped pollen. Explain thisbizarre outcome!
The self-fertilization of an F1 pea plant produced froma parent plant homozygous for yellow and wrinkledseeds and a parent homozygous for green and roundseeds resulted in a pod containing seven F2 peas. (Yellow and round are dominant.) What is the probability that all seven peas in the pod are yellow and round?
We have dealt mainly with only two genes, but the sameprinciples hold for more than two genes. Consider thefollowing cross:A/a ; B/b ; C/c ; D/d ; E/e × a/a ; B/b ; c/c ; D/d ; e/ea. What proportion of progeny will phenotypicallyresemble (1) the first parent, (2) the second parent,(3) either parent, and (4) neither parent?b. What proportion of progeny will be genotypically thesame as (1) the first parent, (2) the second parent,(3) either parent, and (4) neither parent?Assume independent assortment.
A parent pea plant with the genotype Ttrr produces offspring in which half are tal and round and half are short and round. What’s the genotype of the other parent?
Two pink-floweredfour-o’clocks were crossed to each other. What is the probability thata group of six offspring from this cross will be composed of onepink, two white, and three red-flowered plants?
Round (R) seed shape is dominant to wrinkled (r) seed shape in pea plants. If an RR plant is crossed with an rr plant, what is the frequency of phenotypes in the F2 generation? 1)1/4 RR, 1/2 Rr, 1/4 rr 2) All round seeds 3) 3 roundseeds, 1 wrinkled seed 4) All wrinkled seeds
In maize trisomics, n + 1 pollen is not viable. If adominant allele at the B locus produces purple colorinstead of the recessive phenotype bronze and a B b btrisomic plant is pollinated by a B B b plant, whatproportion of the progeny produced will be trisomicand have a bronze phenotype?
Consider this four-factor cross: Tt Rr yy Aa × Tt RR Yy aa, whereT = tall, t = dwarf, R = round, r = wrinkled, Y = yellow, y = green,A = axial, a = terminal. What is the probability that the first three plantswill have round seeds? What is the easiest way to solve this problem?
