Question

How can you determine the genotype of a plant that displays the dominant form of a trait?


A do a testcross with a homozygous recessive plant

B examine the genotype of the plant in question

C perform cross-fertilization with a heterozygous plant

D look at the phenotype of the plant in question

Answer 1

correct answer is option A

Answer 2

Answer:

The correct answer is option A.

Explanation:

To determine the genotype of a plant that displays the dominant form of a trait do a testcross with a homozygous recessive plant. In genetics, test cross can be defined as the process of breeding or crossing of an individual with the phenotypically recessive parent. This is done with the aim of determining the zygosity of the offspring by analysing the proportions of the genes in the phenotype of the offspring.
