The scientific study of heredity is known as
biology
psychology
genetics
principle of dominance
Fertilization is the process of
the joining of the male an female reproductive cells
cloning
the development of an embryo
recessive traits being masked
A specific characteristic of an individual, such as seed color or plant height, is known as a
gene
allele
hybrid
trait
A hybrid is an offspring resulting from
parents with the same traits
parents with different traits
"Factors" passed from parents to offspring that are responsible for an individual's traits
genes
alleles
hybrids
traits
Different forms of a gene, such as green and yellow seed color, are known as
genes
alleles
hybrids
traits
Mendel's principle of dominance states that
all alleles are dominant
all alleles are recessive
some alleles are dominant and some are recessive
organisms only display recessive alleles
Segregation of alleles refers to the fact that
both alleles for a gene from each parent are passed down to offspring
one allele for a gene from each parent are passed down to offspring
The sex cells (sperm & egg) are referred to as
Somatic cells
Gametes
Alleles
Genes
What the organism displays or expresses
Genotype
Phenotype
The alleles an organism has for a particular trait
Genotype
Phenotype
Heterozygous individuals
Have two copies of the dominant allele
Have one copy of each allele
Have two copies of the recessive allele
Homozygous individuals
Have two copies of the dominant allele
Have one copy of each allele
Have two copies of the recessive allele
