Movement disorder is characterized by symptoms often described as pulling, burning, tingling, creepy-crawly, grabbing, buzzing, jitteriness, or gnawing?

The movement disorder is the restless legs syndrome.  This is a confusion that makes a compelling impulse move one's legs. There is frequently a repulsive inclination in the legs that enhance fairly with moving them. Every so often the arms may likewise be influenced. The emotions, by and large, happen when very still and in this way can make it difficult to rest.

a) Possible genotype for the plant: TTAA and TtAa

b) Test cross between the plant and double homozygous recessive can be done to test its genotype.

c) Genotype of plant is TTAA if all progeny from test cross is tall with axial flowers. Genotype of the plant is TtAa if the progeny express both dominant and recessive traits.

This prediction is based on the test cross and can be done with help of punnet square without performing a cross.

d) Test cross determines the genotype of the dominant organisms based on appearance of only dominant or both dominant and recessive traits in the progeny.

Explanation:

a) Since the phenotype of the mysterious plant is dominant, it could be homozygous or heterozygous dominant. So,  the possible genotype for the plant: TTAA and TtAa

b) Test cross between possible genotypes and double homozygous recessive can be done to test its genotype.

Test cross 1 = TTAA x ttaa

Test cross 2  = TtAa x ttaa

c) Genotype of plant is homozygous dominant (TTAA) if all progeny from test cross is tall with axial flowers (TTAA x ttaa= TtAa).

Genotype of the plant is TtAa if the progeny is obtained exhibits following phenotypic ratio=

1 tall plant with axial flower :1 tall plant with terminal flower :1 dwarf plant with axial flower:1 dwarf plant with terminal flower.

This prediction is based on the test cross and can be done with help of punnet square without performing a cross.

d) The homozygous dominant plant does not have recessive alleles and therefore, all the progeny of the test cross express only dominant traits.

On the other hand, if the genotype of the mystery plant was heterozygous dominant, it would form four types of gametes in 1:1:1:1 ratio which in turn would give four types of phenotype in test cross progeny.
