Assume that a recessive allele (f) is associated with a severe language disorder. An unaffected male wants to determine the genotypes of his wife, his parents, and himself. His mother has the language disorder. Neither he nor his wife has the language disorder, but one of their five children does. What is the genotype for each individual? Answers may be used more than once or not at all. (Note: the gene associated with this language disorder is on an autosome.)Mother   Father   Wife   Himself

A human baby boy inherits a recessive allele from his mother. In which circumstance would he most likely show the trait coded for by the recessive allele? Group of answer choicesThe allele is on the X chromosome.The baby inherits the dominant allele from his father.The allele is on an autosomal chromosome and the baby is a twin.The allele is on the Y chromosome.

How many genotypes are possible for this situation?

The most common allele, genotype, or phenotype in a population is referred to as theMultiple Choicewild type.dominant population.recessive population.P generation.F1 generation.

A girl with curly hair and dimples but no freckles has a brother with curly hair and freckles but no dimples. She wanted to figure out the possible genotype for herself and her brother related to these characteristics. She did some research and determined which expression of the traits was dominant and which was recessive. She recorded the information in a chart. If the two children have the same biological parents, what is one of the possible genotypes of each child for these three traits based on their descriptions? Sister    Brother

Presence of the phenotype of an autosomal recessive disorder in one generation and then absence of the phenotype in the next generation likely meansMultiple choice question.the allele is present in heterozygotes that are carrying the disorder.the disorder has mutated into another form.the allele has not been passed to the next generation.the disorder has ceased to exist in the family.
