Describe how traits for eye color, tongue rolling, and tallness are inherited.?

Describe how traits for eye color, tongue rolling, and tallness are inherited. Hint: You don't neeed to know which traits are dominant.Describe how traits for eye color, tongue rolling, and tallness are inherited.?
Eye color and tongue rolling are straight Mendelian traits, one allele on each of the parental chromosome sets ( do not know which chromosome number ) Tallness is a polygenic trait; it is located at approximately 5 loci points ( 10 alleles ) and is additive in expression, or can be epigenetic, where some alleles modify the expression of others.





PS I stand corrected on the eye color. ( below )Describe how traits for eye color, tongue rolling, and tallness are inherited.?
It depends on what chromosomes your parents pass on. If your mom can roll her tongue and her egg cell contains the chromosome then you would be able to roll your tongue.
Sorry to disagree but eye colour is definitely NOT a simple Mendelian inheritance. Google this and the human genome project for an insight. In short, no-one knows as yet - so I don't know why your teacher has asked this.
