<u>Answer:</u>
Charles Darwin’s study of evolution predicts that genetic evidence would show that all organisms share a common ancestor.
Option: (B)
<u>Explanation:
</u>
- Through his "theory of evolution", Darwin found that the species exist and new species form based on natural selection.
- He studied the animals and birds in Galapagos island for his evolution theory.
<u>The four key points of Darwin's Theory of Evolution:</u>
- individuals of any species are not identical;
- genes are passed from one 'generation' to another;
- more offspring are born than can survive;
- only the 'survivors of the competition' for the resources will reproduce.
MUTATIONS lead to duplications actually increase the number of genes in a genome.
It allows the scientist to determine the age of the rock it is in
Since the male and the female have recessive alleles of this gene, all of their offspring will be like that too.
rr x rr cross will result in 100% of the offspring with the genotype: rr
R- dominant (but none of the parents has this allele)
r- recessive
