The right answer is freed the hands for other uses.


bipedality is also more economic than tetrapedality, but it is not as fast and does not offer a high jumping skills.

The standing position has an advantage in reproduction because it has become attractive to females and more or less successful imitation in males, depending on their abilities, but bipedalism is a disadvantage in childbirth.

Shalnov [3]

Igneous rocks are formed by hot melted magma coming from the Earth's core that crystalizes when gets in contact with air. They can be either intrusive or extrusive. B) <em>Large mineral crystals.</em>

<h3>What is the igneous rock?</h3>

These rocks come straight from the interior of the Earth.

A liquid mass of silicate composition comes from the Earth's core. This melted mass comes at an extremely high temperature.

Magma begins to cool and solidify during its ascent to the Earth's surface. It solidifies and crystallizes into igneous rock following the magnetic field orientation.

Thre are two types of igneous rocks

• plutonic rocks ⇒ in areas close to the terrestrial crust ⇒ intrusive

• volcanic rocks ⇒ on the surface ⇒ extrusive

Albinism in humans is caused by homozygosity for mutant recessive alleles of the tyr gene, which is located on chromosome 11. al
yanalaym [24]
Exactly 989527/1048576, or approximately 94.37%  
Since each trait is carried on a different chromosome, the two traits are independent of each other. Since both parents are heterozygous for the trait, each parent can contribute 1 of a possible 4 combinations of the alleles. So there are 16 possible offspring. I'll use "a", "A", "b", "B" to represent each allele and the possible children are aabb, aabB, aaBb, aaBB, aAbb, aAbB, aABb, aABB, Aabb, AabB, AaBb, AaBB, AAbb, AAbB, AABb, and AABB 
Of the above 16 possibilities, there are 7 that are homozygous in an undesired traint and 9 that don't exhibit the undesired trait. So let's first calculate the probability of "what are the chances that all 5 children not exhibiting an undesired trait?" and then subtract that result from 1. So 
1-(9/16)^5 = 1 - 59049/1048576 = 989527/1048576 which is approximately 0.943686485 = 94.3686485%  
So the answer is exactly 989527/1048576, or approximately 94.37%
