Answer:
<h3>Genotype frequencies</h3>
25% DD
50% Dd
25% dd
or
1 DD: 2 Dd: 1 dd
<h3>Phenotype frequencies</h3>
75% Dark brown, 25% light brown
or 3 dark brown: 1 light brown
Explanation:
Two heterozygous parents have the genotypes Dd. Therefore, the cross is Dd x Dd.
D d
D DD Dd
d <em>Dd dd</em>
<em />
25% (1:4) of the organisms have the genotype DD, and therefore the phenotype is dark brown, since it has two copies of the dark brown fur allele (DD)
50% (1:2) of the organisms have the genotype Dd, and therefore, the phenotype is dark brown since dark brown fur (D) is dominant to light brown fur (d).
25% (1:4) of the organisms have the genotype dd, and therefore the phenotype is light brown, since it has two copies of the light brown fur allele (DD)
Answer:
The answer is 50%
Explanation:
The rest of the answers are unreasonable
I think the correct answer from the choices listed above is option A.
The first type of cell to differentiate is a neuron. The neurons are
cells that process and transmits information through electrical and
chemical signals. Hope this answers the question.
Most of the joints in the appendicular skeleton are synovial joints.
So, the correct option is (c).
- A joint, sometimes referred to as an articulation, is where two or more bones come together. The names of two bones are included in each articulation.
- Immobile joints are ones that do not permit movement at the joint sites .These joints don't have a joint cavity; instead, dense fibrous connective tissue, typically collagen, holds the bones physically together.
- A synovial membrane-lined joint capsule that produces synovial fluid surrounds and protects the two of them.
- Specialized joints known as cartilaginous joints can be identified by their structural characteristics.
- In fibrous joints, white connective tissue fibres that travel from one articulating portion to the next separate the articulating parts.
