Organisms that have two identical alleles for a particular trait are said to be
hybrid.
homozygous.
heterozygous.
dominant.
Unlike mitosis, meiosis results in the formation of
two genetically identical cells.
four genetically identical cells.
four genetically different cells.
four genetically identical cells.
In alleles, capital letters show:
Recessive traits.
Dominant traits.
Heterozygous means:
Same alleles. Ex: TT
Different alleles. Ex: Tt
What is true about genotypes?
Genotypes are the physical traits
Genotypes are the allele combinations.
Phenotypes refer to:
Allele combinations.
