A scientist finds a new organism that may be either a bird or a bat, but it is not clear which group it belongs to. He is pretty sure that the organism has analogous structures with bats and homologous structures with birds, as suggested by genomic data. The organism has one trait that is shared with bats but not birds. Which group should he choose for the new organism and why?
A) Bats because of the analogous structures; the trait shared only with bats is ancestral.
B) Birds because of the homologous structures; the trait shared only with bats is ancestral.
C) Birds because of the homologous structures; the trait shared only with bats is derived.

In a classic experiment using pea shape, mendel conducted two separate genetic crosses. in the first cross the parent plants were “true breeding” for pea shape; one had round peas ( r )and the other had wrinkled (r). the first cross produced a filial 1 generation of all round peas. in the second cross, mendel bred plants from the filial 1 generation. this cross produced different results. out of approximately 1000 plants, about 75% were round and 25% were wrinkled.
