One observation in the human pedigree that rules out a recessive pattern of inheritance. Introduction: Genetic disorder are caused due to abnormalities in the genome of a person and these disorders are inheritable from the parents to the offspring. Genetic disorders are of different types depending on the location of the infected genes and the type of allele on the chromosome such as autosomal dominant, autosomal recessive, X-linked dominant, X-linked recessive, Y-linked and mitochondrial disorders. For understanding the inheritance of human genetic diseases “pedigree analysis” is considered the most effective tool and it follows simple Mendelian pattern.

Summary Introduction

To describe: One observation in the human pedigree that rules out a dominant pattern of inheritance.

Introduction: The dominant and recessive pattern of inheritance is observed using the pedigree analysis. For a dominant pattern to be inherited only one of the dominant alleles need to be transferred but the recessive pattern of inheritance requires both the alleles that are transferred to be recessive.

In humans, cystic fibrosis and albinism are both inherited as independently assorting autosomal recessive traits. Use f to represent the recessive allele for cystic fibrosis and F for the allele for the unaffected condition. Use A to represent the dominant allele for normal melanin and a for the recessive allele for albinism. A man is albino and heterozygous for cystic fibrosis. His wife has the unaffected phenotype for both traits, although her father had cystic fibrosis and her mother is albino. 4a. What is the genotype of the wife 4b.What is the probability that a child of this couple is albino and has cystic fibrosis? 4c.What is the probability that a child of this couple is a girl who is albino and has cystic fibrosis? 4d.What is the probability that a child of this couple is normal for both traits?

For a recessive condition, two normal heterozygous individuals have children. What is the likelihood of their children being affected by this condition? What is the likelihood of their children being carriers without the condition? What is the likelihood of their asymptomatic children being carriers? Suppose that an individual with the condition has children with a heterozygous individual, what is the likelihood of their children being carriers?

A maternal effect can cause the offspring phenotype ratio to depart from that of classic Mendelian inheritance. In a species of snail, the dominant allele N codes for right-handed shell coiling and recessive allele n codes for left-handed shell coiling. If an Nn female with right-handed shell coiling mates with an Nn male, what is the shell coiling phenotypic ratio of their offspring? O 3, bidirectional coil : 1, left-handed coil 4, right-handed coil : 0, left-handed coil 3, right-handed coil: 1, left-handed coil 0, right-handed coil : 4, left-handed coil
