one trait is correct answer.
In monohybrid experiment, one trait is followed for definite generations. For example - height of individual.
If two traits ( like color and height ) are followed, it is called dihybrid cross.

Complete a one-trait (monohybrid cross) when given a description of a particular trait and whether the gene for that trait is dominant or recessive. Give predicted results of that trait as percentages or fractions.

3. Consider two traits for a hypothetical animal fur color and ear length. Each trait is controlled by one gene with two alleles. Black fur is dominant to gray fur and long ears are dominant to short. The genes for the two traits are located on different chromosomes. Note: In the following problems, you need to take both traits into account simultaneously a. You cross a true breeding black long-eared male with a true-breeding gray short-eared female. What is the...

mendel found that the organisms expressing a recessive trait A) were pure-breeding B) appeared in the second generation of a cross between two parents with contrasting traits C) all of these are true statements about recessive phenotypes D) could be produced even if neither parent expressed the trait E) disappeared after crossing with a purebred dominant trait

Q. 15, p. 67: Two traits are examined simultaneously in a cross of two pure-breeding pea plant varieties: Pod shape can be either swollen or pinched. Pea color can be either green or yellow. A plant with the traits swollen and green is crossed with a plant with the traits pinched and yellow and a resulting F1 plant is self crossed. A total of 640 F2 progeny are phenotypically categorized as following: 360 swollen yellow, 120 swollen green, 120 pinched...

Consider a cross between two individuals who are heterozygous for three traits (seed shape, color, and flower color), where one allele is dominant and the other allele is recessive. What is the probability that this cross will produce an offspring with ONLY recessive phenotypes for the three traits?

For single crossovers, the frequency of recombinant gametes is half the frequency of crossing over because A) A testeross between a homozygous and heterozygote produces 1/2 heterozygous and 1/2 homozygous progeny.
