The difference in heat distribution between the poles and the equator is due to Earth’s
kkurt [141]
The axis of the earth is tilted (ANSWER IS C). The equator is heated more than other areas because the sun's rays hit it directly.
As you move north or south of the equator, they fall slantingly or obliquely.
When summer is in the south and vice versa, the heat also changes with the earth's rotation.
The tropic of Capricorn and the tropic of Cancer alternately get direct sunlight.

Achondroplasia is a form of dwarfism inherited as a completely dominant trait. Two achondroplastic dwarfs have a dwarf child; la
yulyashka [42]

Answer:

There's 25% probability that their next child will be normal, and 75% of it being a dwarf.

Explanation:

Achondroplasia (A) is a dominant trait.

Two achondroplastic dwarfs (A_ x A_) have a dwarf child (A_) and a normal child (aa). The second child must be aa because if it had a dominant allele it would also be dwarf.

The only way for two achondroplastic parents to have a normal child is that <u>they are both heterozygous (Aa) for this gene.</u>

The cross Aa x Aa would produce the following offspring probabilities:

  • 1/4 AA - dwarf
  • 2/4 Aa - dwarf
  • 1/4 aa - normal

So there's 1/4=25% probability that their next child will be normal, and 3/4=75% of it being a dwarf.
