- A single allele gives rise to the HbS form of hemoglobin. Individuals who are homozygous for the allele HbS/HbS develop sickle-cell anemia Section 9.5. Heterozygous individuals HbA/ HbS have few Symptoms. A couple who are both heterozygous for the HbS allele plan to have children. For each of the pregnancies, determine the probability that their child will be: a. homozygous for the HbS allele b. homozygous for the normal allele HbA c. heterozygous: HbA/HbSThe ABO blood group has three different alleles: F, P, and i.

- Hi, I'm having some trouble with this practice problem from my study guide. If anyone can explain it it would be very helpful! Brindle coloration is a black and brown striping pattern in some dogs. This fur coloration is controlled by different alleles at a single autosomal locus. There are three alleles, KB, kbr and ky. The KB allele is dominant over the other two alleles and produces a solid black color. The allele kbr produces the brindle color pattern and is dominant over the ky allele, which produces yellow fur. Give the genotypes of the parents and offspring in each cross. P: black X yellow; F1: ½ brindle and ½ black P: black X brindle; F1: ½ black, ¼ brindle and ¼ yellow P: brindle X yellow; F1: 100% brindleHb the mutant allele that causes sickle cell anemia is because it impacts multiple pleiotropic polygenic epistatic A Moving to another question will save this response dominant. recessive alleles chromosomes genes phenotypesr blindness is recessive, x-linked trait.
