Homework Answers
1. A new haplotype is received from one of their parents as a result of recombination within the two haplotypes of the parent. This occurs during meiosis when crossing over occurs within the MHC locus. Hence the correct answer is: Crossing over within the MHC locus during meiosis.
2. The mode of inheritance of the haplotypes of the MHC is in a codominant fashion. Hence the correct answer is: The MHC genes are codominant.
If you have any query kindly comment before giving thumbs up. Thank you.

You see a recombination frequency of 50% between two genes. Which of the following possibilities can you exclude? That the genes are located close together on the same chromosome That the genes are on different chromosomes O That the genes are assorting independently That the genes are located on the same chromosome, but very far apart Meiosis contributes to genetic diversity by: o Reducing the number of chromosomes for karyogamy (fusion of nuclei) with another gamete O Recombining homologous chromosomes...

Question 3 1 pts The pedigree shows the inheritance of a disease called Ushers syndrome which affects vision, hearing and balance. Shaded individuals have Ushers syndrome. To study the gene's location 8 molecular markers on Chromosome 11 were used such as D1151888 and D1151310.4 different haplotypes were discovered in the family. The alleles at each marker locus are numbered and the chromosomes from the parents labelled E, F G, H. 1 2 1 3 2 3 2. 1 1 نا...

2. Short tandem repeat polymorphisms (STRPs) are genetic markers that have multiple alleles per locus in the population. Since there are more than 2 alleles for a STRP, we have to use numbers rather than A/a or +/- to indicate their identities. The following pedigree corresponds to the genotype table below. The order of alleles listed for each genotype does not indicate anything about haplotype (e.g. "1,2" could mean 1 is on the maternal chromosome and 2 is on the...

Crossing-Over in Meiosis Meiosis is a process of nuclear division that reduces the number of chromosomes in new cells to half the number in the original cell. The parent cell is diploid (2n), and it begins meiosis with a replicated set of chromosomes. During meiosis, this parent cell Homologou will divide twice to create four haploid (1n) cells. pairs During prophase I of meiosis I, homologous pairs of chromosomes pair up and stick together to form tetrads through the process...

A gene for whisker length is encoded by an autosomal gene and the long whisker allele (H) is dominant to the short whisker allele (h). A second gene located on the X chromosome is responsible for nose color. The brown nose allele (B) is dominant to the pink nose allele (b). A. (8 pts) A male with short whiskers...
