Homework Answers
Some traits are carried on sex chromosomes X,Y .Most traits. Carried on only the x chromosome .Sex influenced traits are autosomal traits that are influenced by sex .If the male has one recessive allele,he will show that trait ,but it will take 2 recessive for that female to show that same trait.

Name Sex-linked traits are genetic char segments of DNA found on chromosomes that Sex-Linked Traits Senetic characteristics determined by genes located on sex chromosomes. Genies are and on chromosomes that carry information for protein production and that are sponsible for the inheritance of specific traits Genes exist in alternative forms called alleics. or a trail is inherited from each parent Like traits originating from genes on autosomes (non-se chromosomes), sex-linked to omosomes), sex-linked traits are passed from parents to offspring...

What are the characteristics of X-linked recessive traits and X-linked dominant traits? Explain this by using examples. How do human cells compensate for the X-linked gene dosage difference in XX and XY nuclei? How are autosomal genes are influenced to sexual dimorphism?

answer only In humans, sex-linked traits (example: colorblindness) are carried by the Y sex chromosome. Select one: a. True b. False The gene for human blood types occurs in more than two alternative forms. Which of the following situations specifically describes this type of inheritance? Select one: a. multiple alleles b. lack of dominance c. nondisjunction d. complete dominance e. incomplete dominance

Which of the following explains why most sex-linked characteristics are X-linked instead of Y-linked? Group of answer choices A All the genes on the Y chromosome are recessive B The X chromosome has more genes than the Y chromosome C Genes on the Y chromosome contain more mutations than on the X chromosome D There are no YY genotypes

1. Based on your understanding of sex-linked recessive traits, would it be possible for the phenotype to skip one or more generations before reappearing? Explain your answer. 2. Proteomics is the study of the number of different proteins that a gene produces. Why might this be a more complete snapshot of human genetics than genomics? 3. If the Huntington’s disease trait is dominant, why is it not more prevalent in the population?
