If two parents have dark hair, the child will most likely have dark hair.
If one has light and the other dark, the child has a 75% chance of having dark hair or a dark-dominated mix because the gene for dark hair is dominant.
If two parents have light hair, the child will most likely have light hair.

Of course, it gets a lot more complicated than this, the genes of the child's grandparents and great grandparents could be carried by the parents as well. So if the parents have dark hair but they each have a parent with light hair, the light hair gene will be carried by them and could be passed on to the child. That's how it is with genetic disorders, such as Systic Fibrosis or Sickle Cell Anemia.

With independent assortment, the ratio of genotypes in the F2 generation of a cross between true-breeding strains (AA bb x aa BB

MariettaO [177]

Answer:

c. Aa Bb

Explanation:

The parents were pure breeding with genotypes AAbb and aaBB. A cross between AAbb and aaBB would produce AaBb genotypes in F1 progeny. Two F1 strains would be crossed to produce F2 progeny. The F2 progeny would have the genotype ratio= 1:2:1:2:4:2:1:2:1.

Out of all the obtained genotypes in the F2 generation, the proportion of "AaBb" genotype was 4/16. Therefore, "4" in the given ratio represents the genotype "AaBb".

moderate temperatures and precipitation, as well as nutrient-rich soil due to annual leaf fall, characterize this biome.

Anna [14]

Moderate temperatures and precipitation, as well as nutrient-rich soil due to annual leaf fall, is characteristic of deciduous forest.

<h3>What exactly is a deciduous forest?</h3>

A forest that is mostly composed of trees that lose their leaves in the fall is known as a deciduous forest.
Among the varieties of deciduous trees found in Wyoming are aspen, cottonwood, box elder, ash, mountain ash, poplars, willows, fruit trees such the wild plum, and, less frequently, oak and maple.
Temperate deciduous woodlands are located in mid-latitude zones, or the areas between the arctic regions and the tropics.
This area has four distinct seasons since the deciduous forest areas are exposed to both warm and cold air masses.

Does the enzyme make the reaction occur faster

Scrat [10]

Answer:

Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.

Which occurs during translation

RideAnS [48]

Answer:

Translation occurs in a structure called the ribosome, which is a factory for the synthesis of proteins. ... Translation of an mRNA molecule by the ribosome occurs in three stages: initiation, elongation, and termination. During initiation, the small ribosomal subunit binds to the start of the mRNA sequence.
