Another name for heterozygous:
purebred
homozygous
hybrid
alleles
Another name for homozygous:
heterozygous
purebred
hybrid
gametes
The process that occurs during Prophase 1 which increases genetic diversity in gametes.
linked genes
fertilization
crossing-over
polyploidy
Linked genes are:
Genes that have genetic mutations
Genes that have too many alleles
Genes that are often passed on together
Genes that code for the same trait
Capital letters are always used for ________ alleles.
Recessive
Dominant
Two dominant OR two recessive alleles for the same trait would be considered ___________.
heterozygous
hybrid
recessive
homozygous
When an allele can "hide" another trait, we say the hidden trait is:
homozygous
linked
recessive
weak
The allele or gene combinations (letters) present is known as the _______.
phenotype
genotype
monohybrid
dihybrid
RR is an example of:
heterozygous recessive
heterozygous dominant
homozygous dominant
homozygous recessive
Tt is an example of:
homozygous
purebred
phenotype
genotype
Tall is an example of an organism's:
genotype
phenotype
In the punnett square picture, the parents:
have the same genotype
are both homozygous
are both heterozygous
have the same phenotype
What percent of the offspring in this cross will have the recessive phenotype?
100%
25%
50%
0%
Extra Credit: How is a dihybrid cross different then a monohybrid cross?
They compare two traits at once.
The dominant traits don't always "hide" recessive traits
They don't follow the rules of basic genetics
They can compare more than 2 traits at once.
