Answer:
The population has evolved because there was a change in allele frequencies.
Explanation:
Answer:
Germs can be spread many ways, including three types of transmission (or passing of germs):
Direct,
Indirect
Airborne.
Direct transmission means person-to-person contact occurs, and the germs are passed that way. Indirect means that someone spread germs onto an object and when the next person touched that object, the germs spread.
Explanation:
It would be A, they both have different properties, as they say it, different functions.
Answer:
A) Traits can be dominant or recessive, and the recessive traits were "hidden" by the dominant ones in the F1.
Explanation:
Mendel discovered the fundamental theory of heredity: that inheritance involves the passing of genes (he called it discrete units of inheritance), from parents to offspring. Those genes are with two alleles in the genotype, one inherited from the father and other inherited from the mother.
When he cross-bred pure-bred parent (always produced offspring identical to the parent) plants dominant traits were always seen in the offspring, while recessive traits were hidden until the first-generation (F1) hybrid plants were left to self-pollinate. Mendel also noticed that in second-generation (F2) of the offspring 3:1 was ratio of dominant to recessive traits.
