What is a trait that will appear in yhe offspring if one of the parents contributes it?
In order for a recessive trait to appear in the offspring, it must inherit a recessive allele for that trait from both parents.
What type of succession are pioneer organisms involved?
they are the last organisms to appear.
What is the fraction of genotypes that appear in offspring?
Genotypic Ratio. Source- My Biology Book
The approach to evolution that involves the study of similar structures that appear during the development of different organisms is known as the study of?
Comparative Embryology- This is the study of similar structures appearing during the embryonic development of related organisms.
When traits do not appear according to the expected ratio in offspring what may have occured?
crossing over

What are 3 ways that a species may form?
They can be formed by evolution: A species can't survive in it's environment so it evolves into a more adapted species Two different species can mate: A new species can appear from the offspring of two different species.
In what Era did the first land dwelling organisms appear?
