Your question: Which genotype represents true dihybrid condition?

So, the correct answer is ‘TtRr’.

What is true dihybrid condition?

A phenomenon in which two organisms with two pairs of traits or contrasting characters are crossed is called a dihybrid cross. In the genotype TtRr, T and R are gametes for dominant traits and t and r are gametes for recessive traits. So it is a true dihybrid condition. So, the correct answer is ‘Tt Rr

What is genotype of dihybrid cross?

A dihybrid cross describes a mating experiment between two organisms that are identically hybrid for two traits. … The offspring of the RRYY x rryy cross, which is called the F1 generation, were all heterozygous plants with round, yellow seeds and the genotype RrYy.

Which is a pure dihybrid?

A dihybrid cross considers two pairs of contrasting characters. TtRr genotype is obtained from the dihybrid cross of TTRR and ttrr which are true breeding homozygous dominant and homozygous recessive breeding lines. TtRr genotype consists of both dominant and recessive alleles for two different traits.

Is true breeding always homozygous?

True breeding means parents are homozygous for every trait. In the pure breeding that occurred in the plants having either recessive or dominant alleles of a gene. Due to the presence of both types of same allele pure breeding produce the progeny of their own kind in the plant.

What is the true breeding line?

True breeding lines are those plants that have been generated through repeated self – pollination and have become homozygous for a particular trait. This trait is then passed onto the future generations if bred with another true breeding plant.

Which of the following is correct for Dihybrid cross?

So, the correct option is ‘1YYRR, 2YyRR, 2yyRr, 4YyRr’.
