Genetics Answers

Research the strengths and weaknesses, advantages and disadvantages of genetic technologies (DNA extraction, DNA amplification, gel electrophoresis, and transformation of cells) to speculate, in an informed manner, about specific future uses of generic engineering technologies. Your counterarguments must include discussion of the reliability and validity of the use of the technologies.

Define DNA

what is the genotype of a colorblind man

Match the correct definition to the correct word:

1) allele A) geneticist that developed a model for genetic crosses

2) homozygous B) father of modern genetics

3) diploid C) having pairs of chromosomes

4) inbreeding D) factor that controls inheritance of traits

5) dominant E) observable characteristic

6) Mendel F) both alleles for a trait are the same

7) F1 generation G) offspring obtained after inbreeding for several generations

8) phenotype H) both alleles for a trait are different

9) F2 generation I) one of the forms of a specific gene

10) Punnett J) a particular characteristic of an organism

11) genes K) process of crossing individuals from the same family

12) pure lines L) a form of a gene that is only expressed if is the only form present

13) genotype M) results of a cross between purebred dominant with purebred recessive

14) recessive N) a form of a gene that is always expressed if present

15) heterozygous O) results of a dihybrid cross

16) trait P) specific set of alleles that code for a trait

What are the different pattern of inheritance and their genotypes? Also examples for them. Such as codominance incomplete dominance multiple alleles and sex linked and blood types

Evaluate possible future uses of genetic engineering technologies

A black guinea pig crossed with an albino guinea pig produced 12 black offspring. When albino was crossed with a second black one, 7 blacks ang 5 albinos were obtained. What is the best explanation for this genetic situation?

The regions on the rna molecule that are translated are called

The processes that lead to variation have been discussed. However, try also to criticise these processes a bit, for example are there any disadvantages to theses processes and their contribution to variation

Assume that the supplier of your primer set informs you that they delivered the wrong forward primer to you. The forward primer sent you is for a gene in another species, with no annealing sites in the human genome. What would your expected result be if you set up your PCR reaction mix using this primer set? Motivate your answer.
