Probability of Inheriting Alleles

The video tutorial discusses a genetics problem involving pedigrees and autosomal recessive inheritance. It explains how to calculate the probability of individuals being carriers and the likelihood of a child inheriting a recessive allele. The tutorial analyzes parental genotypes and concludes with a final probability calculation for the child's genotype.

What type of inheritance pattern is discussed in the video?

• Autosomal dominant

• X-linked recessive

• Mitochondrial

• Autosomal recessive

What is the probability that the first child of individuals 4-3 and 4-4 will have the disease?

• 1/8

• 1/16

• 1/4

• 1/2

If a daughter is a carrier, what is her genotype?

• AA

• aa

• Aa

• aA

What is the probability that a daughter will inherit a recessive allele from her father?

• 1

• 1/4

What is the probability that a female is heterozygous if both her parents are heterozygous?

• 3/4

What is the probability that a child will inherit a recessive allele from both parents?

• 1/48

• 1/96

• 1/24
