Gametes are produced by the process of
mitosis
meiosis
crossing-over
replication
Linked genes
are never separated
assort independently
are on the same chromosome
are always recessive
Gene maps are based on
the frequencies of crossing-over
independent assortment
genetic diversity
the number of genes in a cell
The different forms of a gene are called
traits
pollinations
alleles
hybrids
Organisms that have two identical alleles for a particular trait are said to be
hybrid
homozygous
heterozygous

A tetrad consists of
a homologous pair of chromosomes, each made of two chromatids
the copies of a chromosome that are normally in cells
two sister chromatids that have been replicated diring interphase
a parental chromosome that was replicated to form a pair, then replicated again.
Unlike mitosis, meiosis results in the formation of
diploid cells
haploid cells
2N daughter cells
body cells
The relative locations of each known gene can be shown on a

Situations where one allele for a gene is not completely dominant over another allele for that gene is called
multiple alleles
incomplete dominance
polygenic inheritance
multiple genes
