Question | Answer |
Heredity | The passing of genes from one generation to another |
Genes | A unit of heredity that codes for a particular trait that is located on our chromosomes |
Alleles | Different forms of the same gene (Brown Hair, Blonde Hair, Black Hair, Red Hair) |
Inherited Traits | A trait that is passed on from parents to child through the genes |
Acquired Traits | A trait that is learned through the environment (walking, reading, riding a bike) |
Dominant | This allele can be expressed when only one copy is present. It will cover up another factor because it's stronger- capital letter |
Recessive | This allele is expressed only if two copies are present. It seems to disappear in the person- lowercase letter |
Homozygous | Two of the same alleles (DD or dd) |
Purebred | Another word for homozygous |
Heterozygous | Two different alleles (Dd) |
Hybrid | Another name for heterozygous |
Homozygous recessive | Two recessive alleles (dd) |
Homozygous dominant | Two dominant alleles (DD) |
Phenotype | Physical appearance of a gene (hair color, eye color) |
Genotype | The genes of an organism located on the "inside" of the person (ex: Dd) |
A cat has an allele for red fur but its fur is black. The allele for red fur is | recessive |
What is the genotype that makes a female? | XX |
What is the genotype that makes a male? | XY |
A rabbit with black fur (BB) is crossed with a white fur (bb). What are the chances of having a rabbit baby with white fur? | 0% |
How many total chromosomes are in each human sperm or egg cell? | 23 |
What is the dominant color for a cross between a heterozygous purple flower and a white flower? | Heterozygous would be Tt. The "T" is dominant trait. Question indicated it was a heterozygous purple flower - so purple is dominant and white is recessive. |
