Answer #1

A is False. The corrected form will be - Males do not have two alleles of all genes on X chromosomes. There can be only one allele present on one gene.

In humans the sex of an individual is determined by the sex chromosomes that they inherit. All individuals carry two sex chromosomes, but males carry a so-called X and a Y chromosome (and are thus called XY) whereas females carry two X chromosomes (and are thus called XX). When a male and female produce an offspring, each gives the offspring one of its sex chromosomes, chosen with equal probability. Thus, a child always inherits an X chromosome from its mother...

Which of the following statements about sex determination in Drosophila is false? Transformer along with transformer-2 regulates the splicing of double-sex RNA. The sex-lethal (Sxl) gene is transcribed in female fly embryos, but not in male fly embryos. Only males make functional transformer protein. Double-sex RNA is spliced differently in males and females.

A phenotypic trait is considered sex-linked when a trait occurs only in males the genes for the phenotype occur on X or Y chromosomes the phenotype is expressed only after sexual intercourse the phenotype occurs only in females the phenotype is polygenic for both sexes An individual that has two different alleles for the same trait is said to be polygenic. recessive. homozygotic. heterozygotic. pleiotropic.

6. Red-green color blindness occurs in about 8% of males and .4% of females. Many genes contribute to Red-green colorblindness and most of these are sex-linked, which is the reason for the disparity in the frequency between males and females. Call the allele that encodes a functional product "+" and the allele that encodes a non-functional product "=". Why is Red-green color blindness more fequent in males? a.   because males inherit only a single X chromosome, which means that inheriting...

Which statement regarding vertebrate hemoglobin is false? A. Vertebrates have multiple copies of the genes that code for globins. B. The genes that code for globins diverged only recently. C. In bird and mammals, genes that code for alpha-globin are located on a different chromosome from those that code for beta-globin. D. In fish, genes that code for globins are found on a single chromosome.

Color blindness in humans is controlled by a gene located on the X chromosome (sex-linked). The normal gene, Xc need only be present as a single copy for an individual yo have normal vision. Since males and femaleshave diffrent numberss of X chromosomes , the incidence of color blindnes between sexes. If a color blind man marries a women with normal vision whoses father was color blind, what proportion of there sons and daughters would you expect to be color...

Sex-linked crosses 4. Hemophilia is an X-linked disease, meaning that the gene that causes the disease is found on the X chromosome. Affected males only have to have one allele to have the disease (XhY), while affected females have to have two alleles (XhXh). Imagine that an affected male has children with an unaffected carrier female. a. What are the genotypes of the parents in this cross? b. Draw a Punnett cross to show the offspring of this couple. c....
