When traits show complete dominance, the genotype can be revealed by a test cross. In the example of tall and dwarf plants (Figure) why is it necessary to use the dwarf parent? In general, why is it necessary to use a parent that is homozygous recessive?
In garden peas, one pair of alleles controls the height of the plant, and a second pair of alleles controls flower color. The allele for tall (D) is dominant to the allele for dwarf (d), and the allele for purple (P) is dominant to the allele for white (p). A tall plant with purple flowers crossed with a tall plant with white flowers produces 3/8 tall purple, 1/8 tall white, 3/8 dwarf purple, and 1/8 dwarf white. What is the genotype of the parents? a. Dd Pp x Dd pp b. DD Pp x dd pp c. DD Pp x dd Pp d. Dd Pp x Dd Pp e. Dd pp x dd Pp
In a species of plant, some individuals have smooth leaves and some have hairy leaves. The character (hairy or hairless leaves) is determined by a single gene. What is the simplest way to test the hypothesis that hairy leaves are the dominant trait?
If a homozygous green leaf is represented by YY and a homozygous yellow leaf is represented by yy, what is the correct phenotype of the following alleles: YY, Yy, yy, Yy (in order)? A)Green, Green, Yellow, Green B)Green, Yellow, Green, Yellow C)Yellow, Yellow, Green, Yellow D)Yellow, Green, Green, Green
Gregor Mendel’s pea plant experiments demonstrated that different characteristics are not necessarily inherited together. This is known as which of the following? Group of answer choices A-codominance B-genotypic disparity C-the principle of independent assortment D-the principle of segregation E-homozygote phenotype
A researcher studied six independently assorting genes in a plant. Each gene has a dominant and a recessive allele: R black stem, r red stem; D tall plant, d dwarf plant; C full pods, c constricted pods; O round fruit, o oval fruit; H hairless leaves, h hairy leaves; W purple flower, w white flower From the cross (P1) RrDdccOoHhWw x (P2) RrddCcooHhww, determine: Note: RrDdccOoHhWw is one genotype. a. How many kinds of gametes can be formed by P1?b. How many genotypes are possible among the progeny of this cross?c. How many phenotypes are possible among the progeny?d. What is the probability of obtaining the RrDdccOohhww genotype in the progeny?e. What is the probability of obtaining a black, dwarf, constricted, oval, hairy, purple phenotype in the progeny?
If you needed to determine the genotypes of a phenotypically dominant plant, could design an experiment to do so. What would you choose to cross your unknown plants with in order to determine their genotypes? Explain your answer (you may want to use a Punnett square to do so).
Many of the color varieties of summer squash are determined by two different interacting genes A and B: AA or Aa gives white colored squash, aaBB or aaBb gives yellow squash, and aabb produces green squash. A plant producing white squash is crossed with a plant producing green squash. One half of the offspring produces white squash; the other half produces green squash. What is the genotype of the parent plant producing white squash? AAbb AABB AaBb Aabb AaBB
In flies, small wings are recessive to normal wings. If a cross between two flies produces 8 small-wing offspring and 28 normal-wing offspring, what are the most likely genotypes of the parents? (Use SS to represent the normal-wing allele and ss to represent the short-wing allele.)
A botanist carries out a cross pollination with two red poppies. In the result he obtained 75% red flowers and 25% white flowers. Determine the genotypes of the parents, using the letter R.
A gardener received a pea plant from her neighbor, and she wants to know its genotype. The neighbor told her it produces round peas, which is a dominant trait (R) to wrinkled peas (r). The gardener performs a test cross and observes that half of the offspring plants produce wrinkled peas. What is the genotype of the plant she received from her neighbor?) homozygous recessive, rr heterozygous, Rr homozygous dominant, RR In pea plants, the allele for round peas (R) is dominant to the allele for wrinkled peas (r). A gardener has a plant he got from his neighbor that produces round peas, but he does not know its genotype. What simple procedure could he do to determine the genotype of his new plant?) Perform a dihybrid cross—if only 1 out of 16 offspring are wrinkled, then the new plant’s genotype is RR. Perform a test cross with a plant that has an Rr genotype—if all of the offspring give round seeds, then the new plant’s genotype is Rr. Perform a test cross…
You identify a gene that determines the size of the pods of a pea plant. To study the phenotype associated with this trait, you cross a plant that is homozygous for the “long pod” allele with a pea plant that is homozygote for “short pod” allele. When measuring the length of the pods of the parents and resulting offspring, you obtain the following data: Plant Length (cm) Homozygous (“Wide” allele) 15 cm Homozygous (“Short” allele) 4 cm Resulting cross breed 9 cm What can you conclude about this phenotype/trait? Long and short alleles are codominant Wide allele shows incomplete dominance over the short allele Wide allele shows complete dominance over the short allele Short allele shows complete dominance over the long allele The wide and short genes are linked
