Answer:
Populations have variation in traits due to random mutation, crossing over and environmental conditions.
Answer:
The correct answer is D. The genes are coded to produce specific proteins, by the process of transcription and translation.
These proteins then, lead to the production of characteristic traits like eye color, hair color etc.
So genes indirectly control the traits
Explanation:
Answer:
b.the recipe because it can be passed on to all relatives
Explanation:
A crooked nose is a genetic trait and can be passed to the progeny via genes only. Sexually reproducing organisms such as humans experience segregation of traits during gamete formation. Therefore, crooked nose inheritance is a chance factor regulated by the inheritance of genes and the segregation of alleles. On the other hand, a recipe for chocolate chip cookies can be shared with all the relatives and other individuals of the population by any means without any conditions. Therefore, a recipe will spread more quickly through the population.
I think its the Diurnal Cycle.
