is the study of genes and methods that determine complete DNA sequences and gene function
What is genetics?
The study of individual genes, including the impact of individual genes on relatively rare disorders.
What is genetic evaluation?
Broader than genetic counseling; includes information gathering, information sharing and value-neutral counseling.
mitochondrial chromosomes are known as

What are the 3 characteristics of a gene?
1.exons-coding portions
2.Introns- transcribed into mRNA but not translated into a protein
3.Regulatory regions
Homologous copies of a gene are known as
alleles
On the chromosome the arm above the centromere is called_____ and the arm below the centromere is called ______.
P arm
Q arm
What is Mitosis?
the process of nuclear division in which the chromosomes are duplicated and distributed equally to the daughter cells. Same chromosomal content as the original cell ( diploid number)
What is Meiosis?
cell division that produces reproductive cells in sexually reproducing organisms; the nucleus divides into four nuclei each containing half the chromosome number (leading to gametes in animals and spores in plants)
