information, what are the genotypes of the red parent tulips?
Answer:
According to the information, the parent red tulip plants have a heterozygous genotype for red colour. The allele for red colour is dominant whereas the allele for white colour is recessive. Hence, the recessive allele will be masked by the dominant allele and the parent plants will have red tulips.
When heterozygous red tulip plants will be crossed, then 25% red homozygous plants will be made, 50 % would be red heterozygous plants whereas 25% would be white homozygous.

the explanation is in the answer...
Explanation:
Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).
Molecular biology. DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.
Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.
Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.
Direct observation. We can directly observe small-scale evolution in organisms with short lifecycles (e.g., pesticide-resistant insects).
