Patterns of Inheritance
Different forms of a gene.
allele
The genotype for males.
XY
Monohybrid crosses involve how many traits?
Traits inherited on chromosome pairs 1-22
autosomal
A strand of DNA reads . . .
A - C - T - T - G - A
What will the RNA strand be?
U - G - A - A - C - U
An organism can exhibit this type of trait ONLY if this type of allele was inherited from BOTH parents
recessive
The study of the passing of traits from parent to offspring.
genetics
If one parent is homozygous dominant for a trait and the other parent is homozygous recessive for the same trait, what is the probability that their offspring will have the same genotype of either parent?
0%
If a trait is inherited recessive, the individual must inherit ___ alleles to show the phenotype.
2
3 RNA nucleotides that specifies for amino acids.
codon
The letters used to represent an organism's genetic makeup (for example Bb) is called its ___.
genotype
The physical characteristics or traits of an individual that is displayed. For example height, hair color, blood type, etc.
phenotype
Two unaffected parents produced a child that is affected with a genetic disease. If the disease is autosomal, what is the probability of their next child being affected with the disease as well?
25%
Let f represent an autosomal disease.
Cross two carriers of the disease.
What is the probability of producing an unaffected offspring?
75%
The bond that holds amino acids together.
Peptide
Feather color in a certain type of chicken exhibits incomplete dominance. A black chicken is crossed with a white chicken. This results in a gray chicken. If the letter B represents black and letter b represents white, what is the genotype of the gray offspring?
Bb or heterozygous
Composed of DNA this determines traits.
genes
This disease is inherited as X-link recessive. Cross an unaffected father and a mother who is a carrier. what is the probability of producing an affected offspring?
25%
Let G represent a X-linked disease.
Cross an affected father with an unaffected mother.
What gender will be affected with the disease?
females
The name of the process of creating RNA from DNA.
transcription
In certain flowers the phenotype for RR is red, the phenotype for rr is white and the phenotype for Rr is pink. What type of inheritance patterns in this flower displaying?
incomplete dominance
If an organism has the genotype of mixed alleles, it is said to be...
heterozygous
This trait is inherited incomplete dominance.
Let H represent curly hair
let h represent straight hair.
Cross a wavy hair father with a curly hair mother.
What is the probability of producing a curly hair offspring?
50%
Let Q represent an autosomal dominant disease.
Cross an unaffected father with a heterozygous affected mother. What is the probability of producing a carrier of the disease?
0%
The name of the process of decoding RNA into a polypeptide chain of amino acids
translation
