Cell Division
This type of cell replication occurs in almost all of our cells.
What is mitosis?
This is the loss of eggs due to degradation and re absorption.
What is follicular atresia?
The process of how tissues and organs are formed.
What is morphogenesis?
Having two of the same version of an allele.
What is homozygous?
This type of mutation changes the DNA code, but does not result in changes to the protein sequence.
What is a silent mutation?
The step in cell replication where cells spend most their time. DNA is also replicated during this phase.
What is interphase?
This is the structure in the testes where sperm a produced.
What is the seminiferous tubules?
This is the 16-cell stage of pre-embryonic development.
What is the morula?
The physical result of the alleles you have.
What is phenotype?
Containing three copies of a chromosome.
What is trisomy?
This is the term for a cell with two of each chromosome.
What is diploid?
The changes a sperm must undergo before being able to fertilize an egg.
What is capacitation?
This fluid protects the embryo from physical damage and helps maintain temperature.
What is amniotic fluid?
This disorder causes thick mucus to build up in the lungs and results from a autosomal recessive trait.
What is cystic fibrosis?
What is incomplete penetrance?
The process of chromosomes swapping parts during meiosis.
What is homologous recombination?
During oogenesis these cells will not go on to become eggs.
What is a polar body?
This structure will eventually develop into the digestive and respiratory tract.
What is the yolk sac?
Improved fitness compared to homozygous individuals.
What is heterozygous advantage?
Female calico cats are an example of this genetic concept.
What are mosiacs?
This structure is where microtubules bind to DNA during mitosis and meiosis.
What is a centromere?
This is the outer layer of an egg a sperm must penetrate.
What is the zona pellucida?
These finger like protrusions remove fluid in the uterus that normally prevent blastocysts from contacting the uterine walls.
What are pinopodes?
This autosomal dominant disorder causes neural degeneration and doesn't appear until your 30s and 40s.
The failure of chromosomes to separate properly during meiosis.
What is non-disjunction?
