Based on the observed inheritance pattern and ratio of phenotypes, what are the genotypes of the affected children?   a) If c- = Cystic Fibrosis, the children are c-/c-.   b) If c- = Cystic Fibrosis, the children are C/C.   c) If c- = Cystic Fibrosis, the children are C/c-.

Circle any inheritance patterns that could explain this pedigree. Assume individuals marrying into the family do not have a mutant allele. Please refer to the image attached. A) Paternally imprinted B) Maternally imprinted C) Maternal inheritance D) Autosomal recessive E) Autosomal dominant F) X-linked recessive G) X-linked dominant

2. Hemophilia is an X linked recessive trait. There is a woman who is a carrier for hemophilia and marries a man with hemophilia. a) Complete the Punnett Square (it is a google drawing so you will have to double click it to go to the drawing and type in and around the square. Hold the CONTROL (or Command) button and press the PERIOD button to write a superscript/exponent.) b) What are the possible genotypes of the children? c) Could any of their children have hemophilia? If so, would the child be male or female? Explain your reasoning.

1)If both parents are heterozygous, which genotypes are possible for their offspring? choose all that apply A)homozygous dominant B)heterozygous C)homozygous recessive D)more information would be needed

Albinism is inherited through a recessive allele (a). Juan has normal skin color. His Mom and Dad also have normal skin color. Juan marries Paige, who also has normal skin color. Surprisingly, their first child is an albino. What is everyone's genotype?

A man with hemophilia, an X-linked recessive genetic disease, marries a woman who is a carrier for the same disease. What is the chance that one of their daughters will have hemophilia?  A) 0% B) 25% C) 50% D) 75% E) 100%

Recessive genetic disorders are more frequent than disorders inherited as dominant because : a) recessive genetic disorders are limited to persons of the same ethnicity c) dominant genetic disorders are never expressed in males d) people carrying dominant genetic disorders always die before birth e ) carriers are not eliminated by the disease before reproduction

Identify a disorder caused by a chromosomal abnormality and how the disorder affects the individuals with this disorder. When was this disorder discovered and how often is it seen in today’s population?

In humans, cystic fibrosis is a disease caused by a recessive allele (). Individuals with normal (wildtype) phenotype have the genotype (F). If two heterozygous individuals marry and have 8 children, what is the probability that: a) four will be normal and four will have cystic fibrosis? b) one will have cystic fibrosis and seven will be normal? c) All eight children will have cystic fibrosis?

2) The length of your eyelashes follows an autosomal inheritance pattern. Long eyelashes (E) are dominant over short eyelashes (e). A woman with type AB blood who is heterozygous for eyelashes has children with a man who is heterozygous type-A blood and who has short eyelashes. a) Complete a Punnett square showing the possible genotypes of their offspring. b) What percent of their offspring would have short eyelashes and Type-A blood?
