Students have asked these similar questions
Which statement about analogies is correct? a. They occur only as errors. b. They are synonymous with homologous traits. c. They are derived by similar environmental constraints. d. They are a form of mutation.
When Gregor Mendel first proposed his theories on genetics, they were not recognized. This was because:
A.
Charles Darwin didn't agree with Gregor Mendel's theories.
B.
The current theory was that traits from parents blended together in their offspring.
C.
Gregor Mendel proposed that individuals could change their physical traits during their lifetime and pass those new traits on to their offspring.
D.
Scientists believed there were 5 nucleotide bases, not 4 nucleotide bases.
Organisms heterozygous for a recessive trait are often called carriers of that trait. What does that mean?
