17. Several examples of how scientists use symmetry to identify and group animals in
categories and to study evolutionary relationships are shown in the table.
Type of Symmetry
asymmetry
radial
Description
no distinct body plan
identical structures arranged in a circle
structures divided equally on left and right sides
Examples
sponges
corals
mammals
bilateral
Based on the table, which inference about the relationship between symmetry and
evolution is most accurate?
A
Organisms with different types of symmetry are more closely related than organisms with the same
symmetry
B.
Organisms with the same type of symmetry may be more closely related than organisms with different
symmetries.
C.
Organisms with radial symmetry evolved into organisms that are either asymmetrical or that exhibit bilateral
symmetry.
D.
Organisms with bilateral symmetry evolved into organisms that are either asymmetrical or that exhibit radial
symmetry

Chapter 11.1 & 11.2 notes section 11.1 1. every living thing has a set of ? inherited from its parents. 2. after becoming a ? , mendel spent several years studying ? and mathematics at the university of vienna. 3. during sexual reproduction, male and female reproductive cells join, a process known as ? . 4. pea flowers are normally ? , which means that sperm cells in pollen fertilize the egg cells in the ? flowers. 5. when mendel crossed plants with ? characters for the same trait, the resulting offspring had only one of the characters. 6. a ? is a specific characteristic, such as seed color or plant height, that varies from one individual to another. 7. filius and filia are the latin words for ? and ? . 8. the offspring of crosses between parents with different traits are called ? . 9.to mendel's surprise, all of the offspring had the character of only ? of the parents. 10. mendel's first conclusion was that biological inheritance is determined by ? that are ? from one generation to the next. 11. scientist calls the chemical factors that determine traits ? . 12. mendel's second conclusion is the ? . 13. the principle of dominance states that some alleles are ? and others are ? . 14. when mendel allowed the f1 plants to reproduce by self-pollination the traits controlled by ? alleles reappeared in about ? of the f2 plants in each cross.

Use this new information to determine the parents’ genotypes (indicated by red arrows). then calculate the probabilities that the second male offspring will have each condition. drag one pink label to each pink target and one blue label to each blue target. then use the white labels to answer questions 1 and 2. labels can be used once, more than once, or not at all.
