Sex-influenced or sex-conditioned traits pertains to traits that are phenotypicany expressed depending on whether the individual is male or female.
Sex-limited traits these are characteristics only expressed in one sex.
1. Explain the difference between Sex-influenced and Sex limited traits.
True or False: If the heritability of arm span is 0.68 in humans, then 68% of the length of a person’s arms is controlled by his/her genes. The remaining 32% is controlled by the environment.
Male-pattern baldness is an example of a sex-influenced trait. The baldness allele, which causes hair loss, is influenced by the hormones testosterone and dihydrotestosterone, but only when levels of the two hormones are high. In general, males have much higher levels of these hormones than females, so the baldness allele has a stronger effect in males than in females. (B-baldness; N-full or normal) hair) A normal man marries a normal woman. What can be the possible genotypes of the parents respectively? *
a. BN x BN
b. NN x BN
c. NN x bb
d. NN x BB
e. BN x bb
f. BB x BB

- Two wavy haired people (one male and one female) marry and have eight children. Of these eight, how many would you expect to be curly haired, how many wavy haired and how many straight haired, assuming that the family follows the expected statistically predicted pattern? Suppose you examine the actual children and discover that three of the eight have curly hair. What do you suppose went wrong?arrow_forwardBehavioral geneticists attempted the controversial goal of rooting complex social and behavioral traits like intelligence, educational attainment, or even sexual preference to genetic differences between individuals. In pursuit of these goals, linkage studies and GWAS eventually identified hundreds of genetic variants associated with such behavioral traits. Describe the methods used in large-scale studies on same-sex sexual behavior. Summarize results of such studies. What is your reaction to such findings? Are you convinced that there are indeed gay genes?arrow_forwardAre sex-linked traits, sex-limited traits, and sex influence traits following Mendelian principles of heredity? Why or why not?

- What kind of heritability estimates (broad sense or narrow sense) are obtained from human twin studies?arrow_forwardMid-Digital Hair and FrecklesFinger mid-digital hair (M) is dominant over the recessive trait of no mid-digital hair (m). Freckles (F) is dominant over the recessive trait of no freckles (f). (It is important to note that this example of mid-digital hair and freckles cannot be explained with simple genetics, but for the purpose of this question, assume that it can.)A woman that is heterozygous for freckles and has no mid-digital hair is married to a man with no freckles that is heterozygous for mid-digital hair. The couple is expecting a child. Draw a Punnett square of this cross then answer the following questions: What is the probability that their offspring will have mid-digital hair? What is the probability that two offspring in a row will have no freckles? What is the probability of two offspring in a row having mid-digital hair and freckles?arrow_forwardThe Genetics &IVF Institute developed its XSORT method to increase the probability of conceiving a girl. Among 574 women using that method, 525 had baby girls. Assuming that the method has no effect so that boys and girls are equally likely, find the probability of getting at least 525 girls among 574 babies. Does the result suggest that the XSORT method is effective ? Why? Or why not?arrow_forward
- Identical twins (also called monozygotic twins) are derived from a single egg fertilized by a single sperm, creating a zygote that later divides into two. Because identical twins originate from a single zygote, they are genetically identical. Caroline Loat and her colleagues examined nine measures of social, behavioral, and cognitive ability in 1000 pairs of identical male twins and 1000 pairs of identical female twins (C. S. Loat et al. 2004. Twin Research 7:54–61). They found that, for three of the measures (prosocial behavior, peer problems, and verbal ability), the two male twins of a pair tended to be more alike in their scores than were two female twins of a pair. Propose a possible explanation for this observation. What might this observation indicate about the location of genes that influence prosocial behavior, peer problems, and verbal ability?arrow_forwardIn your own words, explain how genetic ancestry testing works.

- Drosophila buzzati is a fruit fly that feeds on rotting fruits of cacti in Australia. The broad-sense heritability of body size (thorax length) was calculated from a natural population of the fruit flies, and was 0.3. If the phenotypic variance was 5, what is the genetic variance?arrow_forwardWhat limitations or potential biases might be associated with commercial genetic ancestry testing?
