What is chromosomal theory of inheritance? List the ways in which genes and chromosomes behave similarly during meiosis and fertilization.

Extranuclear inheritance can involve genes that are present in:     ribosomes   mitochondria   autosomes   sex chromosomes   In humans, which of the following would be phenotypically male?   Question 5 options:   XO individuals   XX individuals   XXY individuals   XXX individuals     Presence of an abnormal number of copies of an individual chromosome in a cell is a condition known as:     triploidy   heterogamy   aneuploidy   polyploidy

You are an allele on a single uncondensed chromosome in a Yellow fever-carrying mosquito (Aedes aegypti) diploid cell (2n = 6). Demonstrate in as much detail as possible: (1) how you will get to each genetically identical diploid cell of the multicellular offspring. (2) how you will get to the next generation of sexually reproduced progeny.

how can having extra copies of x or y chromosomes create genetic problems?

How does a chromosomal duplication occur?

Assume that each gene is located on a separate chromosome. Parent 1 has the following genotype: AaBbDdEE Parent 2 has the following genotype: aaBbDdEe A) What is the probability of an offspring with genotype: aaBbDDEe B) What is the probability of an offspring with genotype: aaBBDDEE

What are the three key features used to read chromosomes? Go to using karyptypes to predict genetic disorders What is trisomy? What is monosomy? Sketch and describe: metacentric, submetacentric, acrocentric

Why do some genes express themselves later in life? Why not earlier? How many chromosomes in a human that has trisomy-15? How many chromosomes in a human that is triploid?

Which of the following statements best describes an individual whose genetic make-up is shown below? in () 10 11 12 13 14 15 16 17 18 19 20 21 22 The individual is male with the correct number of chromosomes. The individual is female with the correct number of chromosomes. The individual is a male with trisomy. The individual is a female with trisomy. The individual is a female with trisomy.

While working in the lab, you notice that your fruit flies all appear to have an intersex phenotype. This is most likely due to: O There being a 2:3 ratio of X chromosomes to autosomal chromosomes. O There being a 1:2 ratio of X chromosomes to autosomal chromosomes. O There being a 3:2 ratio of X chromosomes to autosomal chromosomes. O There being a 1:1 ratio of X chromosomes to autosomal chromosomes. O There being a 1:2 ratio of Y chromosomes to autosomal chromosomes.
