The chances of the occurrence of the Duchenne muscular dystrophy, which is a sex-linked recessive disorder in the second progeny of a couple named Carla and Rudy, if their first son has this disease Introduction: The disease Duchenne muscular dystrophy is a sex-linked recessive disease, which is caused due to a cross between a male and a female named Carla and Rudy, which are carriers for the disease. It causes the weakness of the muscles of the human body. The first son of the couple is affected and the chance of the occurrence of the disease is 25 % (percentage) in the second child as both the parents are carriers of the disease. The effect is only on one of the chromosome in both the parents, where mutation takes place in a single allele of a gene.

Imagine you are a botanist. Below are characteristics of a never-before described plant species recently identified as part of the ‘All Taxa Biodiversity Inventory’ (ATBI). Field Notes: Specimen collected from shaded area along stream in South Cumberland State Park (Grundy County, TN). Laboratory Analysis: Body: Large leaves emerging from underground rhizome. Size: 63 cm Chromosomal Analysis: Plant body is diploid—chromosome number of 44. Lignin test: Positive Cuticle: Present Leaves: Present—large with branched veins. Underside has sori (containing haploid spores). Roots: Present—branch from the inside. Stem: Present—vascular tissue (xylem & phloem) present. Life History: Diploid sporophyte dominant generation. Haploid spores germinate into heart-shaped, haploid, gametophyte. Water required for fertilization; no seed is produced. Diploid zygote develops into sporophyte. Explain which domain, kingdom and phylum you believe this plant should be classified…
