Chapter 7 Lesson 2

Chromosomes determine all inherited traits because they are made up of

• ATP

• DNA

• centromeres

• phospholipids

Children tend to resemble their parents due to

• heredity

• metabolism

• homeostasis

• responsiveness

A distinguishing characteristic that can be inherited is a(n)

• gene

• cross

• allele

• trait

Which type of inheritance concerns traits that are located on the X chromosome?

• polygenic

• sex-linked

• codominance

• incomplete dominance

If an individual possesses two recessive alleles for the same trait, the individual is said to be

• mutated

• haploid for the trait

• homozygous for the trait

• heterozygous for the trait

The law of segregation deals with which of the following?

• the separation of alleles during meiosis

• the separation of daughter cells during meiosis

• the separation of homologous chromosomes during meiosis

• the separation of homologous chromosomes during mitosis

Which of these was a key factor in the success of Mendel's experiments?

• He started with several different types of plants

• He started with plants that were native to the area

• He started with cross-pollinating, flowering plants

• He started with self-pollinating, purebred plants

Mendel's second law of genetics, the law of independent assortment, is one explanation of the

• final stages of gametogenesis

• random fertilization of gametes

• genetic variation within species

• greater strength of dominant alleles

How are incomplete dominance and codominance different from each other?

What allele is represented in a heterozygous individual?

• Dominant

• Recessive
