Zoe has cystic fibrosis. Which of the following is the most likely explanation? Zoe probably inherited one faulty allele from her father, who is a earner, and one normal allele from her mother. Zoe probably inherited one faulty allele from her mother, who must also have cystic fibrosis, and one normal allele from her father. Zoe must have inherited faulty alleles from both parents, both of whom must also have cystic fibrosis, Zoe must have inherited faulty alleles from both parents, both of whom are earners.

Analysis of X-Linked Dominant and Recessive Traits A young boy is color-blind. His one brother and five sisters are not. The boy has three maternal uncles and four maternal aunts. None of his uncles children or grandchildren is color-blind. One of the maternal aunts married a color-blind man, and half of her children, both male and female, are color-blind. The other aunts married men who have normal color vision. All their daughters have normal vision, but half of their sons are color-blind. a. Which of the boys four grandparents transmitted the gene for color blindness? b. Are any of the boys aunts or uncles color-blind? c. Is either of the boys parents color-blind?
If black and white true-breeding mice are mated and the result is all gray offspring, what inheritance pattern would this be indicative of? dominance codominance multiple alleles incomplete dominance
Use the probability method to calculate the genotypes and genotypic proportions of a cross between AABBCc and Aabbcc parents.
Analysis of X-Linked Dominant and Recessive Traits In the eighteenth century, a young boy with a skin condition known as ichthyosis hystrix gravior was identified. The phenotype of this disorder includes thickening of skin and the formation of loose spines that are sloughed off periodically. This man married and had six sons, all of whom had the same condition. He also had several daughters, all of whom were unaffected. In all succeeding generations, the condition was passed on from father to son. What can you theorize about the location of the gene that causes ichthyosis hystrix gravior?
Mendel performs a cross using a true-breeding pea plant with round, yellow seeds and a true- breeding pea plant with green, wrinkled seeds. What is the probability that offspring will have green, round seeds? Calculate the probability for the F1 and F2 generations.
In addition to codominance, the ABO blood group antigens are also an example of ________. incomplete dominance X-linked recessive inheritance multiple alleles recessive lethal inheritance
A testcross is a way to determine ________. a. phenotype b. genotype c. dominance
The ABO blood groups in humans are expressed as the IAlB, and IAalleles. The allele encodes the A blood group antigen, lBencodes B, and i encodes O. Both A and B are dominant to O. If a heterozygous blood type A parent (IAi) and a heterozygous blood type B parent (IBi) mate, one quarter of their offspring will have AB blood type (IAIB) in which both antigens are expressed equally. Therefore, ABO blood groups are an example of: multiple alleles and incomplete dominance codominance and incomplete dominance incomplete dominance only multiple alleles and codominance

Which is one of the seven characteristics that Mendel observed in pea plants? flower size seed texture leaf shape stem color
