Document Summary

Science dealing with heredity and variation: what is heredity, transmission o physical and psychical characteristics. Incomplete dominance: what is a gene, unit of heredity, what is a chromosome, long linear dna molecule-animals circular- bacteria. Phenotype- the appearance or performance of an animal determined by the genotype (genetic make up and the environment: genotype- determined by two factors, breeding value (what genes are present, non-additive value (how genes are combined) How many chromosomes does an organism have: cattle: 30. Incomplete dominance: complete dominance, over- dominance, co- dominance. Show equal performance for homozygous dominant (aa) and heterozygous (aa) Incomplete dominance: when the heterozygotes is intermediate as the expression of the trait. Over dominance: heterozygous (aa) is superior to homozygous dominant (aa, over-dominance is a condition in genetics where the phenotype of the heterozygote lies outside of the phenotypical range of both homozygote parents. Co-dominance: heterozygous (aa) is intermediate to homozygous dominant (aa) and to homozygous recessive (aa)

Part A:

In prokaryotes and eukaryotes cell reproduction is similar in that it requires some kind of signal to proceed, DNA replication, careful separation of the DNA into two equal portions, and division of the cytoplasm. How is cell reproduction different in prokaryotes and eukaryotes?

Select one:

a. In a eukaryotic organism, the signals for cell division are usually not related to the environment but to the function of the entire organism.

b. Eukaryotic cells constantly divide whenever environmental conditions are adequate and the cells are large enough.

c. The linear chromosomes in prokaryotes are constantly being updated.

d. Prokaryotic cell division requires cytokinesis before mitosis because of their small size.

e. The sexual phase of most prokaryotes (bacteria) is essential to the rapid cell division required for infection.

What does the name Cyclin Dependent Kinase stand for?

Select one:

a. A protein important to the cell cycle that is dependent on DNA synthesis.

b. An enzyme that cuts DNA so that chromosomes can segregate.

Consider two traits for an organism, determined by two genes, each of which is governed by at least two alleles. In the case of a dihybrid individual, the gametes formed will be of either the parental type or the recombinant type. Recombinant type gametes are formed because of
