You might be surprised! My uncle is 170 cm tall, his wife about 165, and two of their sons are about 170. Their third son is nearly 195 cm. Yes, he’s their biological child - we’ve checked!
Both my aunt and uncle had tall fathers and very short mothers. Height is polygenic (multiple genes are responsible), so my cousin won the height allele lottery and inherited a higher proportion of the height increasing traits both parents carried, making him a height outlier.
