Study Notes
Genetics and Reproduction
-
Sexual vs. Asexual Reproduction: Asexual reproduction results in offspring with identical genetic information, while sexual reproduction produces offspring with a new combination of genetic material different from either parent.
-
Mitosis vs. Meiosis: Mitosis produces two identical diploid daughter cells and is involved in asexual reproduction. Meiosis produces four genetically unique haploid cells, is a part of sexual reproduction, and involves recombination.
-
Chromosome Structure: Chromosomes contain many distinct genes, each holding the instructions for producing a specific protein. Genes are segments of DNA. DNA is composed of molecules, and it stores genetic information within the nucleus.
-
Genetic Mutations: Changes in the genetic code (mutations) can be harmful, beneficial, or neutral. Some mutations affect the production of proteins, which can alter traits and, sometimes, the survival of the organism.
-
Genetic Material: Genes are clusters of proteins that make up DNA on chromosomes. Chromosomes are made of tightly wound DNA strands. DNA segments have instructions for protein synthesis. Chromosomes are located in the nucleus.
Genetics in Pea Plants
- Mendel's work studied the inheritance patterns in pea plants.
- He crossed purebred white-flowering plants with purebred purple-flowering plants to produce generation 1.
- Generation 1 offspring were all purple-flowering.
- Crossing two of the generation 1 offspring led to 75% purple-flowering and 25% white-flowering plants in generation 2.
Bacterial Infections and Mutations
- Antibiotics kill most bacteria, but if some survive, they may develop resistance through mutations.
- A mutation in a bacterium can benefit the bacteria by providing protection or the ability to survive the antibiotic.
- This can help the bacteria reproduce more easily, making treatment of bacterial infections more difficult in the future.
