Biology I—Chapter 11 Introduction to Genetics
After reading pages 263-265, I can:
(terms)
1. give
the name for the scientific study of heredity.
2.
name the Austrian monk
credited with the first definitive work on understanding biological
inheritance; name the organism he used in his experimental work.
3.
name the process that occurs when a male sperm cell (pollen in
pants) combines with a female egg cell.
4.
tell what is meant
when an organism is true-breeding.
5.
contrast
self-pollination and cross-pollination.
6.
tell what a trait is.
7.
describe how Mendel
designated his organisms as parental or offspring.
8.
give the term that
describes the off-spring of crosses between parents with different
traits.
9.
tell what genes are
and what they do.
10.
describe how alleles
relate to genes.
After reading pages 265-271, I
can:
(terms)
1. state
the principle of dominance.
2. explain
the concept of segregation of alleles.
3. give
the name for sex cells.
4. tell
how capital and small letters are used to denote the dominance of
alleles.
5. give
the mathematical principle that describes the likelihood a
particular event will occur.
6. describe
how Punnett squares are used in genetics.
7. give
the term that describes an organism that carries two identical
alleles for a trait.
8. give
the term that describes an organism that carries two different
alleles for a trait.
9. contrast
a phenotype and a genotype.
10. name
the genetic principle that describes how genes for one trait can
operate independently from genes of another trait.
After reading pages 272-275, I
can:
(terms)
1. summarize
Mendel’s principles (from the four bulleted items at the top of page
272).
2. name
the situation that occurs when one allele cannot completely dominate
another and the phenotype of the offspring shows a blending of
traits somewhere between the two parent phenotypes (as in pink
flowers resulting from a combination of red and white).
3. name
the situation that occurs when both alleles contribute equally to
the phenotype and the offspring showing traits of both parent
phenotypes (as in speckled black and white chickens from a
black-feathered parent and a white-feathered parent).
4. give
the term used to describe when more than two choices exist in the
genetic code for a particular trait (as in the variety of rabbit fur
colors and human blood types—more than two choices exist for these).
5. give
the name for traits that are controlled by two or more genes (as in
human skin color).
6. name
the organism used by American geneticist Thomas Hunt Morgan in
showing that Mendel’s principles also apply to animals.
7. tell
where genes are located.
8. tell
what is meant when chromosomes are said to be homologous.
9. give
the term that describes a cell that contains both sets of homologous
chromosomes; show how this condition is represented with a symbol.
10. give
the term that describes a cell that contains a single set of
chromosomes, show how this condition is represented with a symbol.
After reading pages 275-280, I
can:
(terms)
1.
name the process that
forms haploid (N) (sex) cells from diploid (2N) cells.
2.
tell how a tetrad is
formed.
3.
describe what happens
during crossing-over.
4.
name the haploid
gamete produced by males; name the haploid gamete produced by
females.
5.
describe the 1911 work
of geneticist Alfred Sturdivant.
