Category A
A record that shows a family tree and family inheritance patterns
What is a Pedigree
The variations of a specific gene are known as
What are alleles
Phenotype is
What is the observable characteristics of genes or genotype
An organism with identical alleles for a particular trait
What is purebred
Which gene is the color blindness gene carried on?
The X or the Y
What is the X gene
The presence of two different alleles for the same gene
What is heterozygous
An allele that can mask or hide the presence of another allele is
What is dominant
Heredity is
What is the transmission of genetic traits from paren to offspring
What color would the offspring of a brown chicken and a black rooster be?
What is both brown and black
True or False
A female can be color blind
What is True
A diagram used to show possible genetic combinations
What is a Punnett square
The condition in which both alleles are partially expressed in a blended appearance
What is incomplete dominance
What two possible genotypes can there be for a black furred rabbit?
What is BB and Bb
What color would the offspring of a white flower and a red flower be if the genes were incompletely dominant
What is pink
What are the problems of inbreeding animals?
What is genetic defects from animals too closely related
The presence of two same alleles for the same gene
What is homozygous
An allele that can be hidden by the presence of another allele is
What is recessive
What is the genotype of a white furred rabbit?
What are two conclusions about genetics Mendel made from his pea plant experiments?
What is
1. Law of Segregation: each parent contributes on gene to a pair of genes
2 Each trait has its own pair of genes
What are the benefits of inbreeding animals?
What is certain traits are magnified
Alleles that display equal power in determining phenotype
What is codominance
An organism that has two different alleles for a particular trait is
What is a hybrid
A cross between a white furred purebred recessive rabbit and a hybrid black furred rabbit would yield what % of white furred and what % of black furred offspring?
What is 50% white furred and 50% black furred
What is the genotype of an incomplete dominance cross between red flowers and white flowers?
What is RW
What is the difference between dominance, codominance and incomplete dominance?
What is
1. Dominant genes mask recessive genes
2. Codominant genes are both expressed equally
3. Incomplete dominant genes are expressed in a blended appearance
