This information is not sufficient. For considering a trait as dominant or recessive, we need data of at least three generations. This data is about only two generations.

Classification is influenced by evolution. The modern system of classification is also called phylogenetic classification; which means it is based on evolutionary relationships. Organism classification is based on the relative similarities and differences between the species. Resemblances of humansRead more
Classification is influenced by evolution. The modern system of classification is also called phylogenetic classification; which means it is based on evolutionary relationships. Organism classification is based on the relative similarities and differences between the species. Resemblances of humans are due to the fact that they evolved from a common ancestor, and their differences are due to adaptations to various types of climate.
Homologus organs are those organs which have the same basic structural design and origin but have different functions. For Example: The forelimbs of humans and the wings of birds look different externally but their skeletal structure is similar. Analogus organs are those organs which have the differRead more
