- Which of the following statements about X-linked recessive inheritance is true? X-linked recessive traits appear more frequently in females than males. X-linked traits are only found in humans. Females who are carriers of an X-linked recessive trait may not exhibit any phenotypic effects. Males have two allele copies of X-linked genes.arrow_forwardA color-blind man marries a woman with normal vision whose father was color-blind. Remember that color-blindness is an X-linked recessive trait. Hint: see figure 12.7 in book. A) What is the probability that their first child will be a color-blind daughter? B) What is the probability that their first son will be color-blind?arrow_forwardName: Class Date Polygenic Inheritance: Cat Coat Color Read aboutthe inheritance of cat coat color In each cat below, predict the phenotype of each genotype and color in each catl Make sure you indicate whether each cat is male or female One gene that affects coat color in cats is an x linked gene we'll call the pigment gene. One allele causes black fur (X) and one allele gives the cat orange fur (X"). These alleles act in a codominant manner, because when a cat has two different alleles (XB Xb), the cat has a pattern called tortoise shell, where the cat has both orange and black hairs. The Y chromosome does not have this coat color gene There is another gene that affects coat color in cats called the piebalding gene. This gene is on an autosomal chromosome and the alleles affect the amount of white patches that appear in the cat's coat, Some cats (ss) have o white patches and their other colors are blended, not patchy. Some cats (SS or Ss) have white patches and their other colors are…arrow_forward
