What device is used to predict the
heritability of a trait?
|
Punnett square
|
|
What type of gene will only be expressed
in the homozygous condition
|
Recessive
|
|
What are alternate forms of the same gene called? For example, for the hair color gene there are different color possibilities, even though it is the same gene (blonde, red, brown)
|
Alleles
|
|
Who is the Father of heredity?
|
Gregor Mendel
|
|
What gene will always show up when it is in any genotype?
|
Dominant gene
|
|
What term means the way a gene is expressed or the way it looks?
|
Phenotype
|
|
What is the science that studies heredity
|
Genetics
|
|
What is any characteristic that is passed from parent to offspring called?
|
Trait
|
|
If one parent is homozygous recessive, what genotype must the other parent have to get only some homozygous recessive offspring
|
The other parent must be heterozygous. That parent must pass the recessive gene on for the offspring to be homozygous recessive, but if that parent had two recessive genes the ALL the offspring would be homozygous recessive
|
|
What is the basic unit of heredity?
|
Gene
|
|
What % of offspring will be heterozygous if both parents are heterozygous?
|
50%
|
|
What type of genotype has one dominant gene and one recessive gene?
|
Heterozygous genotype
|
|
What is another term for the genotype of a hybrid?
|
Heterozygous
|
|
What is the passing of traits from parent to offspring called?
|
Heredity
|
|
What do all the genes of an organism make up?
|
Its genome
