Ch 4 Modern Genetics
Three or more forms of a gene that code for a single trait.
One of the 23 pairs of chromosomes in each body cell.
Y chromosomes are often called this because their alleles are passed from parent to child on a sex chromosome.
A person who has one recessive allele for a trait and one dominant allele.
An abnormal condition that a person inherits through genes or chromosomes.
A chart or "family tree" that tracks which member of a family have a particular trait.
A picture of all the chromosomes in a cell.
The process of selecting organisms with desired traits to be parents of the next generation.
This technique involves crossing two individuals that have similar characteristics.
In this, breeders cross two genetically different individuals.
An organism that has exactly the same genes as the organism from which it was produced.
In this process, genes from organism are transferred into the DNA of another organism.
This process will involve inserting copies of a gene directly into a parent's cells.
All the DNA in one cell of an organism.
