Two brown eyed parents give birth to a blue eye baby. Which trait (blue eyed or brown eyed) is dominant

The brown eyed trait is dominant

Explanation:

This question involves a single gene coding for eye color in humans. The alleles responsible for these traits in the gene are brown alleles (B) and blue allele (b). However, according to this question, two brown eyed parents give birth to a blue eye baby.

The dominant trait is the BROWN-EYES, however, the two brown-eyed parent gave birth to a blue eyed child because the two parents were heterozygous for the trait i.e. contained one brown allele and one blue allele in their respective gene (Bb). Hence, if these two cross, 3/4 of the children will possess the dominant trait (brown eyes) while 1/4 will possess the recessive trait (blue eyes).

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
