Allele — alternative forms of a gene for each variation of a trait of an ... for a trait;
Hybrid — offspring formed by parents having different forms of a specific trait.
The other traits Mendel studied can be substituted for tall and short. ... plants of all
sizes from tall to short; He knew that the tall gene covered up the short gene; C
and ... The F1 plants are tall because the T allele is expressed and "cover up" the
t allele. ... If the alleles are the same, the individual is homozygous f...
Patterns of single gene transmission and expression depend upon ... Many traits
do not adhere to Mendel's laws because they are determined by more than ... If
both alleles are the same, the genotype for that individual is said to be
homozygous. ... Notice from Figure 10.6 above that when the F1 hybrid offspring (
Tt) were ...
For qualitative traits, heterozygotes may resemble one or the other or neither
