Heredity Review

If an organism inherits one dominant allele and one recessive allele for eye color, their genotype would be:

• Haploid

• Homozygous

• Heterozygous

• Homologous

For an XX female to express a recessive sex-linked trait, she must have

• Two recessive alleles

• A Y chromosome

• One recessive allele

• Two dominant alleles

This is the type of inheritance pattern that happens when two dominant alleles blend forming an intermediate phenotype:

• Codominance

• Multiple Alleles

• Polygenic Inheritance

• Incomplete Dominance

Which pair of genes in the diagram to the left would be most likely to be inherited together?

• A and B

• A and C

• C and D

• D and E

The goal of the Human Genome Project was to:

• Identify people with genetic disorders

• Map the location of genes on human chromosomes

• Map the location of chromosomes on genes

• Treat patients with genetic disorders

Two parents have the genotype Gg for a genetic disorder caused by a recessive allele. What is the chance that any of their children will inherit the disorder?

• 25%

• 50%

• 75%

• 100%

Selective breeding produces:

• More offspring

• Less offspring

• Transgenic offspring

• Desired Traits in offspring

The inheritance pattern seen with the blood type AB:

• Multiple Alleles

• Polygenic Inheritance

• Codominance

• Incomplete Dominance

Human height occurs in a continuous range because it is affected by the interaction of many genes, make it a(n):

• Autosomal trait

• Polygenic trait

• Sex-linked trait

• Codominant trait

What law BEST explains why an organism with "Tt" will show only the dominant phenotype?

• Law of Dominance

• Law of Segregation

• Law of Independent Assortment

• Law of Filial Generations
