Biology Chapter 11

Different forms of a gene are called

• hybrids

• dominant factors

• alleles

• recessive factors

If a homozygous tall pea plant and a homozygous short pea plant are crossed,

• the recessive trait seems to disappear

• the offspring are medium height

• no hybrids are produced

• all the offsprings are short

A Punnet square is used to determine the

• probable outcome of a cross

• actual outcome of a cross

• result of mitosis

• result of meiosis

Organisms that have 2 identical alleles for a particular trait are said to be

• hybrid

• heterozygous

• homozygous

• dominant

The physical characteristic of an organism are its

• genetics

• heredity

• phenotype

• genotype

NGSS.HS-LS4-4

A situation in which a gene has more than 2 alleles is known as

• complete dominance

• codominance

• polygenic dominance

• multiple alleles

Unlike mitosis, meiosis in male mammals results in the formation of

• 1 haploid cell

• 3 diploid gamete cells

• 4 diploid gamete cells

• 4 haploid gamete cells

A gene map shows

• the number of possible alleles for a gene

• the relative locations of genes on a chromosome

• where chromosomes are in a cell

• how crossing-over occurs

A situation in which one allele is not completely dominant over another is

• codominance

• incomplete dominance

• multiple alleles

• polygenic dominance

The genetic make up of an organism is its

• phenotype

• heredity

• genotype

• hybrids
