Briefly summarize the processes of mitosis and meiosis indicating where the similarities lie and in which aspects they differ. Explain what is meant by the term ‘linked genes’ with respect to homologous recombination. Identify the different types of chromosomal abnormalities that can lead to disease (e.g. insertions) and in a sentence or two, describe a disorder associated with one of these aberrations. Please use your own words, thanks

describe how anatomy and physiology can be used for many different applications.

Steve independently transformed lentil with either the pea Rms3 or the Rms4 genes, both of which are candidates for increasing lentil leaf size. Describe how he should first test his transgenic lines and then how he should intercross and select for plants that were homozygous for both Rms3 and Rms4.

briefly describe (one or two paragraphs) the process of somatic cell nuclear transfer and how it is used to create cloned cells.
Explain what you consider to be the positive and negative aspects of cloning both scientifically and morally, giving at least three ‘for’ and three ‘against’ points – Discuss whether you think it is a good use of science and will benefit mankind or whether you believe it is unethical and should no longer be pursued? Please use your own words

Keeping in mind the relationship between structure and function, discuss the potential uses of artificial cells and/or cell like materials and whether you consider them to be a good substitute for the natural versions.
You will need to search the internet for your own examples, please cite sources.

When can a mutation in only one of the alleles for a locus in a diploid cell have devastating effects for that cell ?
Group of answer choices
When the mutation affects a haploinsufficient locus
When it causes a synonymous mutation in the protein region of a gene
When it completely abolishes the expression of the mutated allele
When it causes a nonsense mutation downstream of the stop codon of a protein-coding gene
When it affects the coding sequence of a gene that is not normally expressed in a that cell

Given what we know about the relationship between genes, chromosomes, and DNA, why can more than one allele of a gene be present in an indívidual?
Group of answer choices
Because recessive alleles need to be in the presence of another recessive to show their phenotype
This cannot happen; there can be many alleles for a gene, but most organisms will carry only one of them
Most eukaryotic organisms have at least 2 sets of homologous chromosomes
Due to blending inheritance, organisms will combine alleles that they inherit from their parents

1.
Mendel's Law of Segregation says this:
Select one:
alleles are always paired
alleles separate during gamete formation
alleles that are dominant get into gametes more often
alleles that are recessive get into gametes more often
alleles stay together during gamete formation
2.
The use of the garden pea by Mendel was important because it has this ability.
Select one:
to produce only one color
to have a few traits to focus on
have several flower colors on one plant
to self fertilize
only reproduce with another, separate plant
3.
A test cross is used to:
Select one:
determine an unknown genotype using a homozygous recessive individual
determine if there are any alleles
determine if there are more than 2 pairs of alleles
determine an unknown genotype using a homozygous dominant individual
determine if there are 3 or more pairs of alleles
