In secondary neurulation, 

the neural tube arises from the aggregation of mesenchyme cells into a solid cord that subsequently forms cavities that coalesce to create a hollow tube.

Autosomal Recessive Traits

Autosomal recessive traits normally appear with equal frequency in both sexes.

The trait seems to skip generations.

When both parents are heterozygous, approximately one-fourth of the offspring are expected to express the trait.

Recessive traits appear more frequently among the offspring of consanguineous matings.

Example - Tay–Sachs disease, sickle cell anemia, cystic fibrosis, PKU
