The gene that encodes for plant height in sunflower plants follows a strict recessive/dominant pattern of inheritance and has 2 alleles (tall and short). A tall sunflower plant is crossed with a short sunflower plant. Half of the offspring from this cross are tall, and the other half are short. From this information, what are the parents' genotypes

Tall sunflower- Tt

Short sunflower- tt

Explanation:

According to this question involving a gene that encodes plant height in sunflower plants, the allele for tallness (T) exhibits dominance over the allele that codes for shortness (t).

A tall sunflower plant is crossed with a short sunflower plant. Half of the offspring from this cross are tall, and the other half are short. The short plants will possess a genotype "tt" because the short trait can only be expressed when the alleles are the same.

The tall offsprings must possess a heterozygous genotype i.e. Tt. If this cross produced Tt and tt offsprings, hence, the geneotypes of the parents must be:

Tall sunflower parent- Tt

Short sunflower patent - tt

answer: b: experiments that showed that all cells are similar in how they metabolize and in their composition
