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 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?
This is step in cell replication where cells spend most their time. DNA is also replicated during this phase.
What is interphase?
This is the structure with 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 long and results from a autosomal recessive trait.
What is cystic fibrosis?
A chromosomal abnormality in which a male has two X chromosomes and one Y
(XXY)
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?
The failure of chromosomes to separate properly during meiosis.
What is nondisjunction?
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.
Female calico cats are an example of this genetic concept.
What are mosaics?
