A single inherited trait represented by a SINGLE letter | Allele |
The trait that "overpowers" another trait whenever present in a pair of alleles. | Dominant |
A trait that is"overpowered" by another. | Recessive |
A pair of inherited alleles that determine the trait. | Genotype |
The physical expression of a trait | Phenotype |
Two of the same alleles together. | Homozygous/Purebred |
Two different alleles together. | Heterozygous |
Whose genetic information determines the gender of a human baby? | Father |
If a homozygous dominant pair is crossed with a heterozygous pair, what percent of the offspring could be recessive? | zero |
A change in the base sequence of DNA is called a(n)? | Mutation |
The offspring produced by the singe-celled organism is a _________________ of the parent cell. | Clone |
The process used to create "Dolly" the famous sheep is called? | Cloning |
Which sheep will "Dolly" look like? | The sheep that donated the "udder" cell |
The probability that a human offspring will be a male is? | 50% |
Identical twins are formed when? | A fertilized egg splits |
Does the offspring of Clyde and Claire favor one parent or is it random? | Random |
Considering Clyde and Claire, which parent will most likely determine the gender of the child? | Father |
This provides the instructions for all cell activity including genetic traits | DNA |
The Father of modern genetics | Gregor Mendel |
The creator of the tool that is used to determine the probability of the outcome of offspring. | Reginald Punnett |
