- Give typed full explanation Two parents who are each known to be carriers of an autosomal recessive alleles have four children. None of the children has the recessive condition. What is the probability that one or more of the children is a carrier of the recessive allele?MODIFIED TRUE OR FALSE. In the following items, read each statement carefully. I. In humans and other mammals, biological sex is determined by a pair of sex chromosomes: XX in males and XY in females.II. In the sexual pattern of inheritance, an X-linked pattern will be present and can attached both on the X and Y chromosomes. a. The first statement (I) is correct and the second statement (II) is wrong b. The first statement (I) is wrong and the second statement (II) is correct c. Both statements are correct d. Both statements are wrong MODIFIED TRUE OR FALSE. In the following items, read each statement carefully. I. One important event that happens in Meiosis at Prophase 1 is when crossing over between sister chromatids of non-homologous chromosomes takes place.II. This crossing over is the exchange of genetic material that causes variations among individuals. a. The first statement (I) is correct and the second statement (II) is wrong…Give typing answer with explanation and conclusion to all parts The chromosomes drawn below are found in a human skin cell. The lines represent the chromosomes themselves. The letters indicate the location of a particular version of a gene. a) T/F An individual’s offspring are more likely to inherit a D1 and R together than a D1 and T9 together. b) T/F About 50% of the egg cells from this individual will have both T9 and BA5. c) T/F Because r is recessive, the frequency at which the r version of the gene occurs in a population is lower than the frequency at which the R version occurs in the population. d) T/F If the protein produced by the BA gene is involved in the formation of ovaries, then the BA gene is likely located on a sex chromosome. e) T/F Because the genes shown here are found in skin cells, these genes code for proteins required for skin cell function.
- High cancer rates can run in families. Explain how Loss of Heterozygosity relates to this.Question:- A female fruit fly that is heterozygous for the white-eye mutation has red-eyed sons and white-eyed sons in equal proportions: a. regardless of the genotype of the male. b. only when mated with a red-eyed male. c. only when mated with a white-eyed male. d. only when mated with a heterozygous male.Hi im having some trouble with this question, if someone could help solve these with an explanation it would be very helpful! In cats, a gene on the X chromosome (X-linked) makes the protein amelogenin, which helps direct the formation of tooth enamel. A mutation in an amelogenin allele changes the amino acid sequence of the protein and can cause a condition called amelogenesis imperfecta, leading to defects in a cat’s tooth enamel. In one type of amelogenesis imperfecta in cats, the allele associated with the condition, a, acts in a recessive manner. Its dominant counterpart, A, results in normal levels of amelogenin. Additionally, the dominant allele H at an autosomal locus that regulates the expression of the protein Sonic Hedgehog is responsible for polydactyly (the presence of extra digits on each foot, “double paws”) and the expression of its recessive counterpart h results in the absence of polydactyly (having the 5 digits per front paw, and 4 digits per hind paw). A female cat…
- The idea that sperm carry more mutations thanoocytes makes sense. Explain how?(a)Discuss or explain the consequences for a cell if the chromatin could not be remodeled. (b) Does the action of the telemorase enzyme contradict the central dogma of molecular biology? why or why not?GENETICS Question; 1. Give the genotypes and its ratio of the dihybrid cross of FIGURE 7. Regarding this problem, you may refer the genotype of the monohybrid cross of pea flower color in Figure 6.
- Analysis of X-Linked Dominant and Recessive Traits Suppose a couple, both phenotypically normal, have two children: one unaffected daughter and one son affected with a genetic disorder. The phenotype ratio is 1:1, making it difficult to determine whether the trait is autosomal or X-linked. With your knowledge of genetics, what are the genotypes of the parents and children in the autosomal case? In the X-linked case?Analysis of Autosomal Recessive and Dominant Traits a. What pattern of inheritance is suggested by the following pedigree? b. For genotype assignment, assume that the pedigree is for an autosomal dominant trait and that the affected male in the first generation is heterozygous. Assign genotypes to all other individuals in the pedigree.Select the true statements. (can be multiple). Sperm and egg cells are diploid, meaning that they have two copies of the human genome. Somatic cells are haploid, meaning that they have one copy of the human genome. Stem cells are haploid, meaning that they have one copy of the human genome. Somatic cells are diploid, meaning that they have two copies of the human genome.
