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

Question

Describe how traits for eye color, tongue rolling, and tallness are inherited. Hint: You don't neeed to know which traits are dominant.

Answer 1

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 )

Answer 2

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.

Answer 3

eye shade is inherited. the attention shade of human beings is in certainty controlled by way of a pair of alleles one in all that's dominant to the different. B represents the dominant brown eye shade and little b represents the ressesive blue eye shade. working example, if the mummy had blue eyes (bb) and the daddy had brown eyes (BB) then the obtainable mixtures of their young infants eye hues could desire to be: bB BB bb or Bb all of them confirm distinctive eye hues. As for related/indifferent ear lobes and rolling tongues, that's inherited too. something that's handed from mothers and fathers to offspring could desire to be contained interior the gametes, interior the nuclei of the cells. We did this polla few circumstances too and that i think of its merely to confirm and talk and useful introduce the assumption of genetics and how it works.

Answer 4

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.
