Which of the following is true about a plant with the genotype AABbcc?Ĭonsider pea plants with the genotypes GgTt and ggtt.
Which of the following is an example of polygenic inheritance? If a woman with type AB blood marries a man with type O blood, which of the following blood types could their children possibly have? People with type A blood have the genotypes IAIA or IAi, people with type B blood are IBIB or IBi, people with type AB blood are IAIB, and people with type O blood are ii. IA and IB are codominant, and i is recessive to both IA and IB.
The IA allele codes for the A glycoprotein, The IB allele codes for the B glycoprotein, and the i allele doesn’t code for any membrane glycoprotein. There are three alleles for this autosomal gene: IA, IB, and i. In humans, ABO blood types refer to glycoproteins in the membranes of red blood cells. If a woman and her husband are both carriers, what is the probability that their first child will be a phenotypically normal girl?Īssuming independent assortment for all gene pairs, what is the probability that the following parents, AABbCc × AaBbCc, will produce an AaBbCc offspring? Phenylketonuria is an inherited disease caused by a recessive autosomal allele. What is the best explanation for this genetic situation? When the albino was crossed with a second black animal, six blacks and six albinos were obtained. What are the genotypes of the albino’s parents?Ī black guinea pig crossed with an albino guinea pig produced twelve black offspring. A man and woman are both of normal pigmentation and have one child out of three who is albino (without melanin pigmentation). *** Chapter 14 Question 19Īlbinism is an autosomal (not sex-linked) recessive trait.
