B. polygenic inheritance.
C. codominance.
D. multiple allele traits.
Answer: The correct answer is- A) Incomplete dominance.
Incomplete dominance means neither of the allele ( that is dominant and recessive allele) shows its phenotype complelety. In other words, no allele is completely dominant and a heterozygous condition produces an intermediate phenotype that lies between a dominant and a recessive trait.
As per the question, the phenotype of parents are - curly hair and straight hair.
As child expresses and intermediate phenotype that is wavy hair, therefore it is an example of incomplete dominance.
Answer:
The correct answer is option b. "Bilateral symmetry and no cephalization".
Explanation:
"Platyhelminthes" are a type of flatworms that lack circulatory and respiratory organs, and have an unique digestive cavity. Two characteristics that define platyhelminthes are they have bilateral symmetry and no cephalization. Bilateral symmetry means that if you draw a line from the head to the tail of the flatworm, you will obtain two mirror sides. Regarding cephalization, platyhelminthes are considered not fully cephalized as they only have the beginnings of cephalization.

Answer: The order of gut development
Explanation:
A protostome and a deuterostome can be differentiated from each on the basis of order of gut development.
In case of protostome spiral cleavage and determinate take place in which the development of mouth takes primarily and development of anus takes place secondarily.
A deuterostome radical and intermediate cleavage takes place in which development of anus takes place primarily and mouth takes place secondarily.
Answer:
In protostome development, there is spiral radical and indeterminate cleavage. The blastopore becomes the mouth and the coelom forms from the mesoderm. In deuterostomes development, radial and indeterminate cleavage take place.
