Examine the pedigree and answer the following questions; shaded individuals show the trait; genotypes are all unknown. The individual marked with the question mark is of an unknown genotype but lacks the trait. A. What mode of inheritance is the most likely, autosomal recessive or autosomal dominant? State your rationale for full credit. B. What is the genotype of the individual designated with the question mark? (Heterozygous, homozygous, or unknown). C. What are the genotypes of the parents in generation I? (Heterozygous, homozygous, or unknown). D. What are the genotypes of the three children of generation IV? (Heterozygous, homozygous, or unknown).
Examine the pedigree and answer the following questions; shaded individuals show the trait; genotypes are all unknown. The individual marked with the question mark is of an unknown genotype but does have the trait. A. What mode of inheritance is the most likely for this trait, autosomal recessive or autosomal dominant? State your rationale for full credit. B. What is the genotype of the individual marked with the question mark? (Heterozygous, homozygous, or unknown)
Please answer all parts of the following question about genes: PLEASE MAKE A PUNNETT SQUARE 1. For the following cross: Aa Bb cc Dd x Aa Bb CC Dd what is the chance of obtaining an individual who: a) shows all dominant traits? b) shows all recessive traits? c) is phenotypically like the second parent? d) is genotypically like the second parent? e) is heterozygous for all alleles? PLEASE MAKE A PUNNETT SQUARE
Please define the following terms: Gene Allele Dominant Recessive Homozygous Heterozygous
six small pedigrees are displayed. Indicate with J (yes) or N (No) if each pedigree is compatible with each of the following types of inheritance. Assume that the genetic characteristics are common in general population. Use table just like the table below in answering A B C D E F Autosomal Recessive Autosomal Dominant X-bound recessive X-bound dominant Y-Bottom
1. Construct a pedigree chart of the trait traced in the situation below.2. The pedigree chart must be constructed with the names and genotypes at the bottom of every individual in the chart.If it is autosomal: Always use the first letter of the dominant trait to represent the dominant allele. For example, if the dominant trait is red, so the allele R-red, while r-yellow. For example, if the person is homozygous dominant for curly hair, we write CC as his genotype. If sex-linked, do not forget to write the parents’ chromosomes (XX-female, XY-male), with their corresponding superscripts (dominant or recessive). The superscript must be based on the first letter of the disorder. For example, the mother is a carrier of hemophilia (which is x-linked recessive), so we write XHXh. If the father has hemophilia, we write XhY. Put the pedigree chart using code properly. The situation is given below: Trait: NeurofibromatosisThe dominant form is neurofibromatosis, caused by the production of…

Propose the most likely mode of inheritance (autosomal dominant, autosomal recessive, or X-linked recessive) for the following pedigrees. Affected individuals are shown with filled (black)symbols.
Suppose two parents, a father with the genotype AaBbccDd and a mother with the genotype aaBbCcDd, want to have children. Assume the loci are inherited independently of each other. Enter your answers as the most simplified fractions (e.g. 1/8 instead of 2/16). What proportion of the offspring are expected to have: The same genotype as the father? The same phenotype as the father? All dominant phenotypes? All recessive phenotypes?
Epilepsy is a central nervous system (neurological) disorder in which brain activity becomes abnormal, causing seizures or periods of unusual behavior, sensations and sometimes loss of awareness. For epilepsy, the concordance values are 72% for monozygotic twins and 15% for dizygotic twins. 1) Is this a single gene inheritance or multifactorial disease? 2) Is there a strong genetic or environmental cause to the development of this disease? If both genetic and environmental causes are implicated, you have to indicate each of them separately.
As it turned out, one of the tallest Potsdam Guards had an unquenchable attraction to short women. During his tenure as guard, he had numerous clandestine affairs. In each case, children resulted. Subsequently, some of the childrenwho had no way of knowing that they were relatedmarried and had children of their own. Assume that two pairs of genes determine height. The genotype of the 7-foot-tall Potsdam Guard was A9A9B9B9, and the genotype of all of his 5-foot clandestine lovers was AABB. An A9 or B9 allele in the offspring each adds 6 inches to the base height of 5 feet conferred by the AABB genotype. a. What were the genotypes and phenotypes of all the F1 children? b. Diagram the cross between the F1 offspring, and give all possible genotypes and phenotypes of the F2 progeny
A pedigree analysis was performed on the family of a man with schizophrenia. Based on the known concordance statistics, would his MZ twin be at high risk for the disease? Would the twins risk decrease if he were raised in an environment different from that of his schizophrenic brother?
