GRE Subject Test: Biochemistry, Cell, and Molecular Biology › Help with Other Inheritance Patterns
Each of the listed statements about transposable genetic elements in eukaryotic genomes are true except for which one?
Which of the following are examples of codominance?
I. A person with blood type AB
II. A flower that displays a red and white spotted phenotype (both colors are attributed to the same gene; homozygosity for either color makes a flower that is completely red or white)
III. A flower that displays a pink phenotype (a homozygous dominant flower is red and a homozygous recessive flower is white)
IV. An organism whose heterozygous phenotype is identical to the homozygous dominant phenotype
A student determines that color for a new diploid species is conferred by one gene. The student mates a homozygous dominant red mother with a homozygous recessive green father to yeild 100% of offspring that are both red and green. What form of inheritance best describes this?
Crossing foxes that are double heterozygotes for two genes regulating coat color yields 27 grey, 12 red and 9 black offspring. What mechanism explains the ratio of coat color observed in the offspring?
Human beings are capable of having A, B, AB or O blood. While "A" and "B" alleles can be expressed at the same time on red blood cells, O type blood can only be a phenotype if a person has 2 "O" alleles.
Based on this information, what two modes of inheritance contribute to blood type in human beings?
When the expression and subsequent phenotype of one gene is dependent on the expression of another gene, this type of phenonemon is known as __________.
