Colored beans to represent the gene for a certain trait of garden pea. (60 pieces of the same size and shape; 30 pieces of which are of different colors from rest) Procedures: 1. Place the 30 pieces beans (one color) to one container and the other 30 pieces to the other container. Assign which color of beans will represent dominant and recessive genes of a specific trait of garden pea 2. Label the paper container as First Parent P1, male and other P1 female 3. At random, segregate the beans on the Lab table. Assume fertilization occurs and First filial generations (F1) are formed 4. Categorize the formed First filial generations 5. Put all the beans in one container. Assume that all the first filial generations undergo self-fertilization 6. Pick up the beans by two from the container without looking at it and collect the second Filial generation (F2) 7. Categorize the formed Second filial generations into two (2) phenotype, and three (3) genotype classes 8. Fill up Table 15.1 for the…

SUBJECT: GENETICS Topic: Probability 1. Consider albinism a trait to occur in a human family. If two parents areheterozygous for such trait, the probability of having a normally pigmented child is 3//4 and having an albino child is ¼. What is the probability that 2 will be normal and 1 will be albino?
A couple was referred for genetic counseling because they wanted to know the chances of having a child with dwarfism. Both the man and the woman had achondroplasia (MIM 100800), the most common form of short-limbed dwarfism. The couple knew that this condition is inherited as an autosomal dominant trait, but they were unsure what kind of physical manifestations a child would have if it inherited both mutant alleles. They were each heterozygous for the FGFR3 (MIM 134934) allele that causes achondroplasia. Normally, the protein encoded by this gene interacts with growth factors outside the cell and receives signals that control growth and development. In achrodroplasia, a mutation alters the activity of the receptor, resulting in a characteristic form of dwarfism. Because both the normal and mutant forms of the FGFR3 protein act before birth, no treatment for achrondroplasia is available. The parents each carry one normal allele and one mutant allele of FGRF3, and they wanted information on their chances of having a homozygous child. The counsellor briefly reviewed the phenotypic features of individuals with achondroplasia. These include facial features (large head with prominent forehead; small, flat nasal bridge; and prominent jaw), very short stature, and shortening of the arms and legs. Physical examination and skeletal X-ray films are used to diagnose this condition. Final adult height is approximately 4 feet. Because achondroplasia is an autosomal dominant condition, a heterozygote has a 1-in-2, or 50%, chance of passing this trait to his or her offspring. However, about 75% of those with achondroplasia have parents of average size who do not carry the mutant allele. In these cases, achondroplasia is due to a new mutation. In the couple being counseled, each individual is heterozygous, and they are at risk for having a homozygous child with two copies of the mutated gene. Infants with homozygous achondroplasia are either stillborn or die shortly after birth. The counselor recommended prenatal diagnosis via ultrasounds at various stages of development. In addition, a DNA test is available to detect the homozygous condition prenatally. What if the couple wanted prenatal testing so that a normal fetus could be aborted?
