100
The long name for this molecule is Deoxyribonucleic acid.
What is DNA?
100
When a genotype has two identical alleles.
What is homozygous?
100
Hairy knuckles are dominant to non-hairy knuckles in humans. This is the phenotype for Hh.
What is hairy?
100
When the two alleles in a genotype are different.
What is heterozygous?
100
If the genotype is Hh, will the phenotype be the dominant or recessive form of the gene.
What is dominant?
200
DNA has sections called this that code for traits.
What are genes?
200
This is the genetic make-up of an organism.
What is genotype?
200
Another way to say the genotype "tt" is this.
What is homozygous recessive?
200
This is the form of the gene that covers up the recessive form when the genotype is heterozygous.
What is dominant?
200
Cross one parent who is heterozygous for unattached ear lobes with a parent who has attached ear lobes. This is the probability of this couple having a baby who has attached ear lobes. (E)
What is 50%?
300
Hair color, eye color, height are all examples of this.
What are traits?
300
These are the different forms of a trait.
What are alleles?
300
Using the letter H, if curly hair is dominant to straight hair, these are the possible genotypes for curly hair.
What are HH, Hh?
300
This is the type of dominance where the dominant allele completely covers up the recessive allele when the genotype is heterozygous.
What is complete dominance?
300
Cross one parent who is homozygous dominant for a widow's peak with a parent who has no widow's peak. This is the probability of this couple having a baby who does not have a widow's peak.
What is 0%?
400
DNA is wound up around proteins into this type of structure.
What are chromosomes?
400
This is a type of dominance that occurs during a heterozygous genotype when the dominant allele only partially covers up the recessive allele.
What is incomplete dominance?
400
A TT (tall) plant is crossed with a tt (short plant). This is the percentage of plants that will be tall.
What is 100%?
400
This the tool that people use to predict the outcome of a certain cross.
What is a punnett square?
400
Two short haired (dominant) guinea pigs are mated several times. Out of 100 offspring, 25 of them have long hair. These are the probable genotypes of the parents. (H)
What is Hh?
500
After meiosis, a cell with with this many chromosomes is produced.
What is 23 chromosomes?
500
This is the visible appearance of a trait.
What is phenotype?
500
In guinea pigs, the allele for short hair is dominant. This is the genotype that a purebreeding short haired guinea pig would have? (H)
What is HH?
500
Another word for a cross is this.
What is fertilization?
500
Black hair is homozygous dominant. Brown hair is heterozygous. Blonde hair is homozygous recessive. (This is an example of incomplete dominance.) A woman with brown hair marries a man with brown hair. These are the possible outcomes for their kids. Give probability for each phenotype.
What are 25% black hair, 50% brown hair and 25% blonde hair?
