Round (R), wrinkled (r) yellow (Y) green (y). What is the phenotypic ratio b/w an RrYy and rryy

Mendel crossed purebred purple-flowered plants with purebred white-flowered plants, & all of the resulting offspring

Genes located close enough together on a chromosome that they are usually inherited together:

A principle in biology that genes are located on chromosomes & accounts for the behavior of chromosomes during meiosis

Chromosomes that are not sex chromosomes are called:

A family tree representing the occurrence of heritable traits in parents and offspring across a number of generations:

if a person w/ achondroplasia mates w/ a person who doesn't have achondroplasia, what percentage achondroplasia children

The expression of two different alleles of a gene in a heterozygote:

An individual who is heterozygous for a recessively inherited disorder and doesn't show symptoms of that disorder

Which technique is used to collect fetal cells during pregnancy for genetic testing?

Having two identical alleles for a given gene is called __________.

A mating between a purebred purple-flowered pea plant and a purebred white-flowered pea plant would produce a(n) ______.

Type of inheritance which the phenotype of a heterozygote is intermediate b/w phenotypes

The genetic makeup of an organism is called the __________.

What would you examine to determine whether a trait is sex linked?

What is the key to the recognition of codominance?

A unit of inheritance in DNA consisting of a specific nucleotide sequence that makes a polypeptide
