I'm pretty sure the recessive allele is expressed in a heterozygous individual.
Just letting u know tho, I'm not completely sure
Hope it is right and helps u tho...lemme know :)
Venules is the correct answer
Earth formed 4.6 billion years ago, and it wasn't until approximately 3.5 billion years ago that we estimate the first prokaryotic unicellular organism existed. The first eukaryote organism probably evolved 2 billion years ago, with the first multicellular organisms evolving about 1 billion years ago.
If 1 centimeter (cm) represents 10 million years (mya), then the 4.6 billion years of the existence of Earth would represent 4.6 meters (m), with the 4.6 m mark being the present.
This means that if we made a timeline with these dimensions, the origin of life would be at the 1.1 meters (110 cm) mark, the eukaryotic life forms appearing at the 2.6 m mark, and the first multicellular organisms around the 3.6 m mark.
