Mendel observed several traits that have two different forms. For example, the height of pea plants is controlled by two different
S7L3. Students will recognize how biological traits are passed on to successive generations.
c. Recognize that selective breeding can produce plants or animals with desired traits.
is process of selecting a few organisms with desired traits to serve as parents of the next generation.
This is generally used to increase the value of the plant and animal.
Dairy cows are bred to produce larger quantities of milk.
Varieties of fruits and vegetables are bred to resist disease and insect pests.
involves the crossing of two individuals that have identical or similar sets of alleles.
This results in the offspring having alleles that are very similar to those of the parents.
The goal is to produce breeds of animals with specific traits.
Problems with inbreeding:
Inbreeding increases the probability that the organism may inherit alleles that lead to genetic disorders.
Is the process used to produce an organism that is genetically identical to the organism from which it was produced.
This can be done with plants and animals.
Dolly the sheep
Scientists believe and hope that cloning will allow humans to live healthier lives.
What are some possible ethical issues that could result from cloning?
genes from one organism are transferred into the DNA of another organism.
This is sometimes gene splicing.
