Explain the underlying molecular mechanisms of incompletedominance, overdominance, and codominance.

State two factors that influence single-gene inheritence patterns?

Crossing over (that can be measured) occurs between:

How do complete dominance, incomplete dominance, and codominance differ?

Describe the chromosomal alterations and phenotype of cri du chat syndrome and Prader-Willi syndrome.

Give bilological term for an alternation in the genetic material that can be inherited.

Predict the phenotypes associated with the following mutant states. For each of the four conditions (a-d) below, indicate which of the six organs (i-vi) would be present at birth in an XX individual, and which would be present in an XY individual. i. testes i1. ovaries iii. male internal sex organs (e.g., the prostate) iv. female internal sex organs (e.g., the uterus) v. male external sex organs (e.g., the penis) vi. female external sex organs (e.g., the clitoris) a. Homozygosity or hemizygosity for nonfunctional alleles of the androgen receptor gene, which is X-linked. b. Hemizygosity for a nonfunctional allele of the SRY gene. c. Homozygosity for a nonfunctional allele of the gene specifying the anti-Müllerian hormone receptor. d. Homozygosity for nonfunctional alleles of the 5a-reductase gene.

A female that is a carrier for DMD has kids with a normal male. Show work. a) What is the chance (%) that these two parents will have a kid with DMD? b) Their first child is a son. What is the chance (%) that he will have DMD?  Hint:  Look at only the male offspring when you answer this question.

Explain the important characteristics of dominance.

Name: Class Date Polygenic Inheritance: Cat Coat Color Read aboutthe inheritance of cat coat color In each cat below, predict the phenotype of each genotype and color in each catl Make sure you indicate whether each cat is male or female One gene that affects coat color in cats is an x linked gene we'll call the pigment gene. One allele causes black fur (X) and one allele gives the cat orange fur (X"). These alleles act in a codominant manner, because when a cat has two different alleles (XB Xb), the cat has a pattern called tortoise shell, where the cat has both orange and black hairs. The Y chromosome does not have this coat color gene There is another gene that affects coat color in cats called the piebalding gene. This gene is on an autosomal chromosome and the alleles affect the amount of white patches that appear in the cat's coat, Some cats (ss) have o white patches and their other colors are blended, not patchy. Some cats (SS or Ss) have white patches and their other colors are…
