- Species I has 2 n = 8 chromosomes and species II has 2 n = 14 chromosomes. What would the expected chromosome numbers be in individuals with the following chromosome mutations? Give all possible answers. Q. Allotetraploidy including species I and IIwe discuss various mechanisms of sex determination, including the XX/XY system of placental mammals, and the ZZ/ZW system of birds. Monotremes, the most primitive mammals, have a very intriguing sex determination scheme that shares elements of both of these systems. Please use the internet to learn more about how sex in monotremes is determined. Then write a short essay (300-400 words) describing this system and comparing/contrasting it to the XX/XY and ZZ/ZW systems.Salamanders have a male heterogametic system for sex determinations where females are ZZ and males are ZW. The allele for the color of the tail is sex linked and the red allele is found on the W chromosome and the blue allele is found on the Z chromosome. You mate a male and female and they have 3 female offspring. What is the phenotypic ratio for tail color for their offspring? Group of answer choices 2 Blue : 1 Red 0 Blue : 3 Red 1 Blue : 2 red 3 Blue : 0 Red
- Species I has 2 n = 8 chromosomes and species II has 2 n = 14 chromosomes. What would the expected chromosome numbers be in individuals with the following chromosome mutations? Give all possible answers. Q. Allotriploidy including species I and IIAbout 40% of Solomon Islanders carry a gene for blond hair, and yet only 5%–10% of these people actually have blond hair. Why is the number of people with blond hair only 5%–10% when so many people carry genes for blond hair? The duck-billed platypus has a unique mechanism of sex determination: females have five pairs of X chromosomes (X1X1X2X2X3X3X4X4X5X5) and males have five pairs of X and Y chromosomes (X1Y1X2Y2X3Y3X4Y4X5Y5). Do you think each of the X and Y chromosome pairs in males assort independently of other X and Y pairs during meiosis? Why or why not? How is the inheritance of X-linked traits different from the inheritance of autosomal traits? How is the inheritance of X-linked and autosomal traits similar? List as many differences and similarities as you can.Termites have a haplo-diploid sex determination system where females develop from a fertilized egg (they are diploid, having one allele from the female cueen and one allele from the male), and males develop from unfertilized eggs (they are haploid, having only one allele from the queen). Assuming that the female parent (queen) is heterozygous for a particular gene, what is the probability that a female offspring will inherit the recessive allele from her mother? What is the probability that a male offspring will inherit a recessive allele from his mother? O A. The probability that a daughter will inherit a recessive allele from her mother is 50%; the probability that a son will inherit a recessive allele from his mather is 50%. OB. Ihe probobility that a daughter will inherit a recessive allele from her mother is 0%; the probability that a son will inherit a recessive allele from his mother is 100%. O C. The probability that a daughter will inherit a recessive allele from her mother is…
- What specific observations (evidence) support the conclusions about sex determination in Drosophila and humans? Sort each observation to the appropriate bin. If an observation applies to both Drosophila and humans, sort it to the "Both" bin. If an observation does not apply to either Drosophila or humans, sort it to the "Neither" bin. Reset Help Three sets of autosomes per X chromosome are required for male fertility. Sex chromosomes are heteromorphic. Maleness is determined by lack of X chromosomes. Triploid individuals (3n) could be phenotypically normal females. XO individuals are male. More than one Y chromosome is needed for maleness. Diploid XXY individuals are abnormal males. Drosophila only Humans only Both Neither Submit Request AnswerSpecies I has 2 n = 8 chromosomes and species II has 2 n = 14 chromosomes. What would the expected chromosome numbers be in individuals with the following chromosome mutations? Give all possible answers. Q. Trisomy in species IDrosophila have XX/XY sex determination systems just like mammals. In Drosophila, loci for both eye color and body color are on the X chromosome. Red eye color (R) is dominant to white eye color (r), and tan body color (T) is dominant to yellow body color (t). Which of the following is the genotype for a female with a yellow body and red eyes, who is homozygous for eye color? Group of answer choices XRT XrT XRt XRT XRt XRt XRt XRT
- In certain salamanders, the sex of a genetic female can be altered, changing her into a functional male; these salamanders are called sexreversed males. When a sex-reversed male is mated with a normal female, approximately 23 of the offspring are female and 13 are male. How is sex determined in these salamanders? Explain the results of this cross.Consider a Droscophilia fly with a genotype of Nn XqYY. The dominant allele of the sex-linked gene specifies a black body and the recessive a white body. The recessive autosomal allele specifies hairy bristles while the dominant allele specifies smooth bristles. i)What is the ploidy of this fly? ii) What would the sex of this fly be? iii)What would the phenotype of this fly be with respect to these two loci?Species I has 2 n = 8 chromosomes and species II has 2 n = 14 chromosomes. What would the expected chromosome numbers be in individuals with the following chromosome mutations? Give all possible answers. Q. Monosomy in species II
