*why do sex-linked traits (X- linked traits) such as red-green colorblindness (which is recessive) display a different pattern of genetic inheritance from autosomal recessive traits? and does it make a difference whether the sex-linked trait is dominant rather than recessive? how? *what are the chances a boy will be colorblind if his mothers father was color blind?

Consider an X-linked recessive trait that is present in 5% of the males in a population. Assume Hardy-Weinberg equilibrium and a 1:1 sex ratio in the population. What is the frequency of the trait in the females of that population? Refer to question 7. What is the frequency of carrier females in that population? ** I understand how to do part one but not sure how to do part two. The correct answer is 0.0950**

What is the probability that for a particular trait, two heterozygous parents will both contribute a recessive allele to their child? For a typical Mendelian trait with complete dominance how many different phenotypes are possible? For alleles that display incomplete dominance, how many phenotypes are possible? Some phenotypes appear to be expressed on a continuum. Several traits in this lab demonstrate this. If most genes have only two alleles, how can some phenotypes be so variable? Chin shape genes are...

Hemophilia is an x-linked recessive trait. In a population of 2000 people, 4 women have hemophilia, 30 men have hemophilia, and 80 are carriers of the disorder. What is the frequency of the hemophilia allele? (Assume the population is 50% men and 50% women.) a.0.059 b.0.033 c.0.057 d.0.039 e.0.038 In a population of 15,000 individuals, 1350 express a recessive trait. How many heterozygotes are there expected to be? a.2100 b.3150 c.6300 d.1800 e.4200

10. Red green colorblindness is an X-linked recessive disease. That means that it is carried on the X chromosome, so men have just one copy of the gene while women have two. In women, both copies must be the recessive disease allele in order to show the disease phenotype, but because men only have one allele, just one recessive allele causes the disease phenotype. Matt and Kate both have normal vision, but Kate's father is colorblind. Use X for the...
