26. In sheep, eye color is controlled by a single gene with two alleles. When a homozygousbrown-eyed sheep is crossed with a homozygous green-eyed sheep, blue-eyed offspringare produced. If the blue-eyed sheep are mated with each other, what percent of theiroffspring will most likely have brown eyes?(A) 0%(B) 25%(С) 50%(D) 75%(E) 100%27. In peas the trait for tall plants is dominant (T) and the trait for short plants is recessive (t).The trait for yellow seed color is dominant (Y) and the trait for green seed color isrecessive (y). A cross between two plants results in 296 tall yellow plants and 104 tallgreen plants. Which of the following are most likely to be the genotypes of the parents?(A) TTYY x TTYY(В) ТТуу х TТYу(C) TtYy x TtYy(D) TtYy x TTYY(E) TtYY x Ttyy28. In humans, red-green color blindness is a sexlinked recessive trait. If a man and a womanproduce a color-blind son, which of the following must be true?(A) The father is color-blind.(B) Both parents carry the allele for color blindness.(C) Neither parent carries the allele for color blindness.(D) The father carries the allele for color blindness.(E) The mother carries the allele for color blindness.29. In the pedigree below, squares represent males and circles represent females. Individualswho express a particular trait are represented by shaded figures. Which of the followingpatterns of inheritance best explains the transmission of the trait?(A) Sex linked dominant(B) Sex linked recessive(C) Autosomal recessive(D) Autosomal dominant(E) Incompletely dominant
