They were caused by different genes.
Fair skin and red hair are caused by different genes in modern humans, than they were in Neanderthals.
yes, a huge lot!
Fossilized skeletons and DNA testing.
Plants only inherit few physical characteristics, while Humans often inherit many physical features.
All modern humans, except Sub-Sahara Africans, carry 1 to 4 percent Neanderthal DNA in their genome.
DNA evidence. A recent study based on DNA proves that modern humans and Neanderthals interbred.
polygene inheritance
It is the eye color
a combination of factors, including competition with modern humans, interbreeding, and environmental changes such as climate fluctuations. These factors likely contributed to the decline and eventual extinction of the Neandertals.
how do the limbs of a pig differ markedly from those of humans?
Linked gene inheritance. In humans, it is called x-linked inheritance; sex-linked inheritance is when the trait is carried on the X chromosome.
B) codominance
