Chapter 3, Problem 26QP
Summary Introduction
To predict: The pedigree chart for the family with the youngest son affected by albinism.
Introduction: Albinism is an autosomal recessive condition where the pigment melanin is lost from the skin that provides color to the skin. The skin becomes whitish and pale and is prone to damage under sunlight.

Mendel's Law of Independent Assortment states that:
the members of a pair of homologous chromosemes assort independently of each other during gamete formation
none of these
the members of a pair of homologous chromosomes separate from each other during gamete formati
different pairs of homologous chromosomes assort independently of each other during gamete formation
different pairs of homologous chromosomes separate from each other during gamete formation
Mendel’s observation that two different traits could be inherited independently of each other can be explained by understanding that:
During meiosis, the process of chromosome assortment into daughter cells is random
Alleles of the genes reside on homologous chromosomes
All of the listed choices are correct
During meiosis, maternal and paternal members of homologous chromosomes are distributed separately into daughter cells
When Gregor Mendel was working in the mid 1800s, scientists had not yet discovered chromosomes or meiosis. However, we now understand how Mendel's principles are rooted in the events of meiosis. As an example of this, state Mendel's principle of independent assortment and explain how it relates to independent assortment in meiosis.

- Assume that color blindness is a recessive character on the X chromosome.

What are the probable genotypes of all individuals?arrow_forwardCystic fibrosis is a recessive human condition.

- The gene for nose shape is found on the X chromosome. Round nose is dominant to pointed nose. Human individuals with XXY (an additional X chromosome) are male. Individuals with XO (only one X chromosome) are female. For the following family, identify the possible nondisjunction events (rare mistakes during meiosis) that could explain the phenotype of the child. A man with a pointed nose and a woman with a round nose have a daughter with a round nose. This daughter has Turner Syndrome (genotype XO: one X chromosome). Nondisjunction must have occurred in melosis 2 of the mother More than one of the answers is correct Nondisjunction must have occurred in meiosis 1 of the father Nondisjunction must have occurred in meiosis 1 of the mother Nondisjunction must have occurred in meiosis 2 of the fatherarrow_forwardA WOMAN IS HETEROZYGOUS FOR TWO HARMFUL RECESSIVE ALLELES IN DIFFERENT CHROMOSOMES, ONE FOR PHENYLKETONURIA (PKU) AND THE OTHER FOR CYSTIC FIBROSIS (CF).
