Is a tall pea plants dominant to short?
In pea plants, tall (T) plants are dominant over short (t) plants. A cross between two pea plants produces offspring in which approximately 50% of the flowers are white and 50% are purple.
What is the genotype of a tall pea plant?
Let us explain by taking example of pea plant. The genotype of a tall pea plant is not known, whether it is homozygous (TT) or heterozygous (Tt). This tall pea plant is crossed to dwarf pea plant (tt). Dwarfness is recessive to dominant allele T for tallness.
What is the genotype of tall pea plant and dwarf pea plant?
c) State the expected ratio of genotype TT and Tt in F2 progeny. Q4. A pure tall and a pure dwarf plant were crossed to produce offsprings….
| T | T | |
|---|---|---|
| t | Tt (Tall) | Tt (Tall) |
What is the genotype for a short pea plant?
The answer is c. tt.
What are the genotypes of a homozygous and a heterozygous tall pea plant?
This makes the inheritance easy to observe and follow. What are the genotypes of a homozygous and a heterozygous tall pea plant? DD is homozygous dominant, gives phenotype tall. Dd is heterozygous, also gives the phenotype tall.
What are the heterozygous genotypes?
(HEH-teh-roh-ZY-gus JEE-noh-tipe) The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).
Is tall a genotype or phenotype?
Tall. What is the phenotype of a pea plant that is heterozygous ( Tt )? It is also tall. The answer is yes, two different genotypes can result in the same phenotype….
| Genotype | Definition | Example |
|---|---|---|
| Homozygous recessive | Two recessive alleles | tt |
Is a tall pea plant homozygous or heterozygous?
Dwarf plant is always homozygous (tt) as tallness is dominant allele and the dwarfness is recessive allele in pea. It produces gametes with ‘t’ allele only. All the gametes produced by tall plant will be only of one type carrying ‘T’ allele if it is homozygous tall (TT). and thus all the offsprings will be tall (Tt).
What is the genotype for a heterozygous pea plant for round and green seeds?
A pea plant with yellow round seeds is crossed with another plant with green wrinkled seeds. The genotype of yellow round seeds is YYRR and the genotype of green wrinkled seeds is yyrr. In the ${F_1}$ generation, the progenies obtained are heterozygous yellow round since yellow and round are dominant characters.
When a tall pea plant is crossed to a dwarf pea plant?
The F1 progeny produced by the crossing of pure tall pea plant with pure dwarf pea plant, is put through to self pollination, in the upcoming generation 1 homozygous tall 2 heterozygous tall 1 homozygous dwarf progeny are produced. The ratio obtained between the homozygous tall and homozygous dwarf is 1:1.
What is the genotype of a homozygous tall pea plant?
genotype TT
a homozygous tall pea plant will have the genotype TT. A homozygous short pea plant will have the genotype tt.
When a tall pea plant is crossed with a short pea plant?
When a tall and short plant are crossed, all of the offspring are tall. If the offspring self-fertilize, they produce tall and short plants in a ratio of 3:1 in the next generation. Mendel’s actual counts were 787 tall:277 short plants in this generation (2.84:1 ratio).
