If two white sheep produce a black offspring, the parent's genotype for color must be

not enough information was given

Mendel's view of the mechanism of heredity was radically different from the prevailing view of the time because he saw heredity working through ______

segments of DNA (genes) that encode proteins, which ultimately control traits of the offspring

a blending of heritable factors in offspring, much as a combination of blue and red pigments produces purple color

particles that travel throughout the body, capturing particular characteristics, before the particles ultimately come to reside in sperm and egg for transmission to the next generation

unchanging (immutable), heritable factors that were contributed by each parent and never mixed

In a test cross, F 2 refers to ____

the second filial generation (the grandchildren of the original mating pair)

the grandparents of the 1st generation

Imagine a particular trait that is determined by a single gene. If this gene is present in two forms, how can you tell which allele is dominant and which is recessive?

Do a test cross between two true-breeding individuals and observe the trait expressed by the F 1 plants.

The trait that is most common in the population is the one determined by the dominant allele

Do a test cross between two true-breeding individuals and observe the characteristic expressed by the F 2 plants.

Cross one of the F 1 individuals to either of the parents.

In an individual of genotype Aa , where are the A and a alleles physically located?

One allele is on one chromosome, and the other is in the same position (locus) on the homologous chromosome

They are both on one chromosome

One allele is on one chromosome, and the other allele is on a different, nonhomologous chromosome

One allele is on one chromosome, and the other is in a different position (locus) on the homologous chromosome

Mendel's principle of independent assortment applies to the ____

independent assortment of alleles of one gene relative to the alleles of any other gene

independent assortment of one member of a homologous pair of chromosomes (a homolog) relative to the other member of the homologous pair (the other homolog)

independent assortment of a pair of alleles in the formation of sex cells

segregation of a pair of alleles in the formation of sex cells

Imagine that long fins in zebrafish is a dominant trait. A breeder wants to set up a breeding program beginning with homozygous dominant long-finned fish. If she obtains a handful of the long-finned fish, how can she tell which if any of these are homozygous for the trait?

Cross the long-finned fish with short-finned fish; if the offspring are all long-finned, the long-finned parent is homozygous

Cross the long-finned fish with short-finned fish; if four-fifths of the offspring are long-finned and one-fifth are short-finned, the long-finned parent is homozygous

Cross the long-finned fish with short-finned fish; if three-fourths of the offspring are long-finned and one-fourth are short-finned, the long-finned parent is homozygous

Cross the long-finned fish with short-finned fish; if half the offspring are long-finned and half are short-finned, the long-finned parent is homozygous

When applied to Mendel's experiments, the term true-breeding means a self-fertilization of two plants that produces _____

offspring identical to the parent

offspring with only dominant traits

offspring with only recessive traits

Homologous pairs of chromosomes frequently ____

carry different genes for different characters

are not both present in diploid cells

What is a Monohybrid Cross?

Involves a single pair of genes, or one trait.

The trait that appears in the homozygous condition.

Is used to predict the probability that certain traits will be inherited by offspring.

The case when one allele is not completely dominant over another.

Recessive alleles may not be expressed because they are

the least common allele in a population.

the most common allele in a population.

less likely to have crossing over.

When is a recessive allele expressed in offspring?

when parents have no dominant alleles

when the offspring is heterozygous
