Q1. Which of these inheritance patterns would be the most likely explanation of the given pedigree?

Autosomal Recessive

Mitochondrial

X-linked Recessive

Autosomal Dominant

Based on the answer to Q1, what is the probability that the new-born male marked with ?1 will be affected by the condition?

25%

50%

100%

If the child marked ?2 was NOT affected by the condition. What would you tell the father of that child?

You are not a carrier of the condition but your child is.

You are a carrier of the condition but your child is not.

You are a carrier of the condition and so is your child

You are both affected but we can’t detect the disease yet

Which of the following options is the most likely explanation of the Given pedigree.

Autosomal Dominant

X-linked Recessive

Y-linked

Mitochondrial

If we assume that this condition is inherited in an autosomal dominant way, then what was the likelihood that all 5 of the third generation offspring in the single family were affected?

1/10

1/50

1/32

1/2

Mitochondrial disease can manifest due to mutations in the genomic or mitochondrial DNA. Therefore the phenotype of the disease isn’t sufficient to predict the inheritance pattern. However, which of these symptoms might increase your suspicions that this is a sign of mitochondrial mutation? There are multiple correct answers here, can you get that one.

Scleroderma

Gout

Poor Growth

Asthama

Do any of these common modes of inheritance explain this pedigree? If so, which is most likely? *

Multiple gene disorder

Non-genetic disorder

X-linked recessive

Autosomal Dominant

The affected female at the bottom of the pedigree comes to you for advice about her future children. What would you tell her?

Your male children would have the disorder, your female children would be unaffected and would not be carriers

Your male children would have the disorder, your female children would be unaffected carriers

Your male children would have a 50/50 chance of being affected by the disorder, your female children would have a 50/50 chance of being carriers.

Your male children will be unaffected, your female children will be unaffected carriers

The female at top right remarried (hence connected to two males). The had a daughter. What is that daughter’s genotype?
