The remaining questions go together. In a species of collared lizard (Crotaphytus collaris), long tail (T) is dominant to short tail (t), and green scalation (G) is dominant to brown scalation (g). Both tail length and scale color are autosomal traits. But green scalation is a x-linked"-limited trait only expressed in males – females have brown scales regardless of G/g genotype. In addition, T is a recessive lethal allele – TT homozygotes do not develop. A long-tailed brown male mates with a long-tailed brown female. Their first two viable offspring are a short-tailed green male a long-tailed brown male. What is the genotype of the father? ["", "", "", "", ""] What is the genotype of the mother?

Like cats, ogres have X-linked fur colors. They can have either an X that is blue or an X that is green. If a Green male ogre and a Green/Blue spotted female ogre have children. Use XG for green and XB for blue. What percent of FEMALE offspring will have green fur? ____50%_____ (use table below) Blue and green fur? ________50%_______________ What percent of MALE offspring will have green fur? Tell me how you determined this. Related: Explain why (under normal circumstances) female ogres can be Green, Blue, or Green and Blue checkered/spotted whereas male ogres can only be solid Green or solid Blue. You find a rare 1/3000 chance of a male ogre that is green and blue checkered. Give one scenario that might explain this male.
I will be adding two questions here because I asked two of the same questions twice by accident earlier. A man and a woman do not have hemophilioa, but the womans father did. (Hemophilia is X-linked recessive). a) What is the probability that they will have a child with hemophilia? b) Is it possible for any of their daughters to be affected? Explain. A cross between a horse homozygous for red hair and a horse homozygous for white hair results in offspring with the coat colour called roan. When you look at the fur of the roan offspring you see both red and white hairs. What type of inheritance best explains this? a) blending inheritance b)codominance c)incomplete codominance d)multiple alleles
The Delacour family is descended from the Veela race, a semi-human, semi-magical humanoid people reminiscent of the Sirens in Greek mythology with special powers. Imagine that being a Veela and having these powers is a X-Linked Dominant trait that is passed on genetically. (Hint: Use the Punnett Square.) What are the possible genotypes for Fleur and Bill’s daughter, Victoire? What are the genotypic frequencies related to the female children (in percentage format)? What is the likelihood (in percentage format) that Victoire would express Veela powers?
Duchenne muscular dystrophy is an X-linked, recessive disorder in which muscles waste away early in life, resulting in death in the teens or twenties. A man and woman in their late thirties have five children—three boys (ages 1, 3, and 10 years) and two girls (ages 5 and 7 years). The oldest, boy shows symptoms of the disease. What are the probabilities that their other children will develop the disease? Give only typing answer with explanation and conclusion
Choose correct option and do explain. Considering an X-linked dominant trait, if an affected woman and an unaffected man decide to have children, which of the answer choices is possible for their children? a. All of their sons are expected to show the dominant trait. b. Their daughters are expected be heterozygous for the gene. c. Their daughters are not expected to show the dominant trait. d. Their sons are expected to be heterozygous for the gene. e. All their children, whether male or female, are expected to show the dominant trait.
A man who is a dwarf due to achondroplasia and has normal vision marries a color-blind woman of normal height. The man's father was 6 feet tall, and both the woman's parents were of average height. Achondroplasia is autosomal dominant, and red-green color blindness is X-linked recessive. What are the possible genotypes and phenotypes of their children? What are the ratios for each? For full credit, you must show all work.
Hemophilia is another example of a X-linked disease caused when a recessive allele (Xh) is expressed. If a normal male reproduces with a heterozygous normal female, what are the expected genotypes and phenotypes? Will any of their daughters develop hemophilia? you must also give the gender of the child in your genotype and phenotype descriptions here.
X-linked ichthyosis is an X-linked recessive trait that manifests in part as dry, scaly skin (“ichthy-” = fish or fish like). Suppose a couple are considering having a child together. Parent A is heterozygous for the ichthyosis allele while Parent B is hemizygous negative for the ichthyosis allele. What is the probability their child would be unafflicted with ichthyosis but be a carrier of the ichthyosis-causing allele? a.0% b.25% c.50% d.75% e.100%
Hemophilia is another example of a X-linked disease caused when a recessive allele (Xh) is expressed. If a normal male reproduces with a heterozygous normal female, what are the expected genotypes and phenotypes? Will any of their daughters develop hemophilia? As in the previous question, you must also give the gender of the child in your genotype and phenotype descriptions here.
Duchenne muscular dystrophy (DMD), marked by muscular degeneration, results from an X- linked recessive gene. Thus, a female who is heterozygous for this gene and does not have the disease can be a carrier. What kind of offspring can you expect from a DMD-affected male and a carrier female? Can there be a carrier male?
The next four questions go together. Cystic fibrosis (f) and deafness (d) are caused by two unlinked autosomal recessive alleles, and colorblindness is caused by an X-linked recessive allele Xc. A female who is deaf and is a carrier for cystic fibrosis and colorblindness marries a male who is colorblind and is a carrier for cystic fibrosis and deafness. I. What are the female's and male's genotypes? II) What is the probability their first child is a phenotypically normal female? Enter your answer as percent without the percent sign to two digits (e.g. 12.34). III) What is the probability their first child is a phenotypically normal male? Enter your answer as percent without the percent sign to two digits (e.g. 12.34). IV) What is the probability their first child has all three conditions ? Enter your answer as percent without the percent sign to two digits (e.g. 12.34).
Note: Don't copy from internet, Also answer correctly in terms of diploid, hemizygous, and carrier!! Thanks Explain why genetic disorders caused by recessive alleles of X-linked genes appear more frequently in males than in females? In your explanation, please include explanations of the following terms: diploid, hemizygous, carrier.
