the image shows two siblings with their grandparents. which best explains why the siblings look more like each other and less like their grandparents? the siblings are more closely related to each other than they are to their grandparents. each sibling is more closely related to the grandparents than to the other sibling. the grandparents do not have any shared characteristics in common with the siblings. the grandparents do not have any shared characteristics with one another.
Answer
Brief Explanations:
Genetic relatedness explains physical resemblance among family members. Siblings share the same parents and inherit approximately 50% of their genes from each parent, resulting in siblings sharing, on average, 50% of their genes with each other. Grandchildren inherit 50% of their genes from one parent, who in turn inherited 50% of their genes from their parent (the grandparent). Therefore, a grandchild shares approximately 25% of their genes with each grandparent (0.5 * 0.5 = 0.25). Because siblings share a higher percentage of genes with each other compared to the percentage they share with their grandparents, they tend to resemble each other more closely.
Answer:
The siblings are more closely related to each other than they are to their grandparents.
