BB
When two alleles in a pair are different (Bb or Mm) they are called
homozygous
heterozygous
trait
genotype
When two alleles in a pair are the same (BB or bb) they are called
heterozygous
gamete
homozygous
zygote
Law of Dominance states
the pair of alleles for a gene will be separated into different gametes
a dominant allele will mask the presence of a recessive allele
during gamete formation, the distribution of the alleles is random
Law of Segregation states
the pair of alleles for a gene will be separated into different gametes
a dominant allele will mask the presence of a recessive allele
during gamete formation, the distribution of the alleles is random
Law of Independent Assortment states
the pair of alleles for a gene will be separated into different gametes
a dominant allele will mask the presence of a recessive allele
during gamete formation, the distribution of the alleles is random
Different forms of a gene are called
recessive
dominant
gametes
alleles
The allele masked by the dominant one
gamete
recessive
zygote
cross-fertilization
The "stronger" of two alleles expressed
dominant
recessive
gamete
gene
Any characteristic that can be passed from parent to offspring
heterozygous
homozygous
trait
allele
A different form of a gene
allele
trait
gene
recessive
An organism's genetic makeup (consisting of 2 alleles), represented as letters (Yy or YY) is called the
genotype
phenotype
gene
allele
An organism's physical appearance, as determined by its genotype (TT = tall or tt = short) is called the
allele
genotype
phenotype
trait
When gametes from two different plants are united through fertilization is called
cross-fertilization
self-pollination
Law of Segregation
zygote
When gametes from the same plant are united through fertilization is called
cross-fertilization
