If a homozygous dominant individual is crossed with a homozygous dwarf, the offspring will have. As shown in the figure a cross between two heterozygous tall plants results in 25% homozygous tall, 50% heterozygous tall and 25% dwarf plants. Thus the correct answer is option C. Answer verified by Topp

The most accurate description of an organism with genotype

This cross can be shown by a cross for the tall (dominant) or dwarf (recessive) feature of pea plant as shown. Thus, if the result is all tall plants then the genotype of the parent will be homozygous dominant (TT) and if the result is 50% tall and 50% dwarf then the parent will be heterozygous dominant (Tt) If dwarfism was dominant characters, it would have expressed itself in F 1 generation. The selfing of heterozygous tall plants yields F 2 generation with the genotypic ratio of 1 TT (homozygous tall): 2 Tt (heterozygous tall): 1 tt (homozygous dwarf). Thus, the correct answer is option B

AA x Aa 3) If tall (D) is dominant to dwarf (d) and two homozygous varieties DD and dd are crossed, then what kind of offspring will be. Explaination: Dwarfness is a recessive trait which is expressed only in homozygous condition; so, he was sure of the genotype of the dwarf plant as tt. 65. A cross was carried out between two pea plants showing the contrasting traits of height of the plant A tall plant with purple flowers crossed with a dwarf plant with white flowers produces 1/4 tall purple, 1/4 tall white, 1/4 dwarf purple, and 1/4 dwarf white. Hair color in this breed is controlled by an incompletely dominant gene. The two homozygous forms are either red or white, and the heterozygous is roan.. Air the tall plant is heterozygous, by definition the short gene is recessive and the short phenotype can only result from a homozygous recessive gene combination. Let's use T to represent the tall gene and s to represent the short gene. The het.. DD = tall (homozygous dominant) Dd = tall (heterozygous) when two alleles go walking, the TALL allele does the talking dd = dwarf (homozygous recessive) Mendel was smart to use peas, most stocks are completely true-breeding = homozygous And he made sure they were homozygous before doing crosse
