Document Summary

Offspring acquire genes from parents by inheriting chromosomes: Parents provide their offspring with coded information in the form of hereditary units called genes. The genes we obtain from our parents are those that link us to our familial bonds, ands are the reasons we resemble our parents (like eye color) Genes program the specific traits that emerge as we develop into adults. The program is written in the language of dna, the polymer of four nucleotides. The inherited information is passed on in the form of each genes specific sequence of dna nucleotides. The language is symbolic formed from mental images. Genes program cells to synthesize specific enzymes and other proteins whose action produces an organism"s inherited traits. The transmission of hereditary traits plays a part in dna replication n (producing copies of genes to be passed from the parents to the offspring). Gametes gametes unit passing on genes of both parents to offspring.

How was it established that particular phenotypes are inherited as a result of genetic information present in the chloroplast rather than in the nucleus?

The organelle heredity is detected when the paternal parent has more influence than the maternal parent over the phenotype of the offspring. In addition, assuming other factors such as X-linked inheritance can be eliminated, different results from reciprocal crosses support inheritance by extranuclear elements.

The organelle heredity is detected when the maternal parent has more influence than the paternal parent over the phenotype of the offspring. In addition, assuming other factors such as X-linked inheritance can be eliminated, different results from backcrosses support inheritance by extranuclear elements.

Describe a specific example of a cross between two parents, eachhomozygous for different traits, which wouldresult in a phenotype that is distinct from eitherparental phenotype.

1. Indicate the genotype and phenotype of each parentand the offspring.
2. Indicate the inheritance pattern of the characterdescribed.

Rules:
1. You may use imaginary organisms. Crosses involving dragons,hobbits, and unicorns are allowed.
2. The distinct offspring phenotype may not be a result ofmutations.
3. Describe a cross that is not described in your textbook.

3. In the early 1800âs, French biologist Jean Baptist Lamark proposed that organisms inherited traits which their parents had acquired over their lifetimes. For example, the giraffe which stretched out its neck in an effort to get food would pass on a longer neck to its offspring. This explained why animals only evolved in ways that benefited them. Critique what is known as âLamarkian Evolutionâ.
