In a field of sunflower plants, 776 plants are tall and 224 plants are short. Sunflower height follows the normal pattern of inh
eritance. Dominant traits masks recessive. Tall (T) is dominant and short (t) is recessive. What is the genotype of the short plants in the field? A) T
B) TT
C) Tt
D) tt
Recessive traits need a homozygous condition to get expressed and to produce a particular phenotype. In contrast, dominant trait can be expressed in homozygous as well as heterozygous condition of the alleles of a gene.
Now, shortness is a recessive trait encoded by allele "t". Hence, allele "t" must be present in the homozygous condition in order to make the plant short.
Thus, the genotype of all the short plants in the field should be tt and the genotype of the tall plants would be TT or Tt.
Deer have following specific features that help it to detect the presence of predators like lion in a forest or grassland: Big ears to hear movement of predators very easily. Eyes on the sides of its head which allow it to see in all directions at the same time.
