Some traits that can be counted and expressed in whole numbers, such as bristle number in Drosophila, are: O A) continuous traits B) deletion C) genome D) meristic traits E) quantitative F) species G) threshold traits H) variation

The term "homoplasy" is most applicable to which of these features? A) The legless condiion found in various types of lizards  B) The 5-digit condition of human hands and bat wings C) The beta-hemoglobin genes of mice and of humans  D) The fur that covers Australian moles and North American moles  E) The basic skeletal features of dog forelims and cat forelimbs.    Based on these choices, I am torn between A) and D). Both represent situations of possible convergent evolution, but I feel like fur isn't too significant of a derived character compared to legless conditions. B) could also be the answer too, but the 5-digit condition seems like common ancestry/morphological similarities.

Which of the following choices accurately describe what makes one person different from another with regard to traits (such as height) that have a very high heritability?  Choose all that apply a) What makes us different is not that we have different genes, but that we have different alleles of many of those genes b) What makes us different from each other is that we have different genes from each other c) Random factors during development is the most significant causes of differences between people d) Most of us have exactly the same genes and alleles, and it’s the environment we were raised in that makes us different e) None of the other choices are accurate

Suppose that a newly identified mutation in humans causes formation of tooth tissue in the nasal cavity. What class of developmental genes would you expect to be mutated in this case? O a) Gap genes O b) Maternal-effect genes c) Pair-rule genes O d) Binary switch genes

Cystic fibrosis is an autosomal recessive disorder that affects 1 in 3 000 newborns with Caucasian background. It causes thick mucus build up in various organs and can cause damages and problems in respiratory and digestive systems. a) What is the frequency of the cystic fibrosis allele in the Caucasian population? Show all your work and express your answer as a value between 0 and 1 rounded to two decimal places.  b) What percentage of the Caucasian population would be carriers for cystic fibrosis? Show all your work and express your answer rounded to two decimal places.  c)If two individuals are carriers of the cystic fibrosis allele, what is the probability that they would have a girl without cystic fibrosis? Show all your work (including the Punnett square) and express your answer as a value between 0 and 1 rounded to two decimal places.

a) what feature of the genome is likely to be located between the two LD blocks that allows scientists to visualize them as seperate blocks? b) Even though the fugure analyzes nine different SNPs, genotyping just two of se SNPs would allow you to predict the genotype of almost everyone in the population. Explain why this limited genotyping has predictive value. c) When obtaining the data allowing construction of triangular diagrams, have researchers typically genotyped common SNPs or rare SNPs? Explain.

At the beginning of the 20th century, scientists argued whether DNA or protein would be the element of "inheritance?" a) Which molecule did they think would carry all the genetic information and why? b) Describe the contribution of Griffith, Avery et al., Hershey & Chase, and Watson and Crick in the field of genetics.

Curly hair is due to a dominant allele in humans. Straight hair is a recessice allele. the heterozygous condition produces wavy hair, a. phenotype that appears as a blend of the two alleles. This is an example of which of the following patterns of inheritance.   a) Simple dominant b) Sex linkage C) Multiple allele d)Incomplete dominance
