Answer:
how are genes expressed for a particular trait?
Genes are expressed in two ways which could be either genotype or phenotype
genotype reflects the dominancy or recessives of a particular trait over another while phenotype entails the physical expression of such trait which could be height, color of skin among others
e.g
If P is purple while p is white
PP x Pp= PP, Pp, PP. Pp these are the genotype produced from the crossing of two parents which results into 2 homozygous gene and 2 heterozygous gene without any recessive gene
while the phenotype shows that all the offspring are Purple

Answer:
The correct answer will be-
1. Weed- 40%
2. Fruit fly- 60 %
3. Mice- 97.5 %
4. Chimpanzee-98.5 %
Explanation:
Charles Darwin suggested that all organism on earth have descended from a common ancestor. The modern technology-enabled humans to sequence the genome of an organism and compared them with each other.
When the human genome was compared with the genome of other organism found the similar sequences in them like - Weed shared 40% of the genome with humans, fruit fly shared 60% genome, mice showed 97.5% genome similarity and chimpanzees showed 98.5 % with the human genome.
On the basis of this, the chimpanzee was found to be the closest species to humans
