The genes for miniature wings (m) and garnet eyes (g) are approximately 8 map units apart on chromosome 1 in Drosophila. Phenoty
pically wild-type females (m + g / mg +) were mated to miniature-winged males with garnet eyes. Which of the following phenotypic classes reflect offspring that were generated as a result of a crossover event?
1. garnet eyes
2. wild type
3 .miniature wings
4 .miniature wings, garnet eyes
Two types of posterity can be created subsequent to mating: parental and recombinant. Recombinants are created because of the traverse of non-sister chromatids at the hour of gamete arrangement. Here, mating happens between m+g/mg+ female and mg/mg male so the posterity would be separated as follows:
m+g/mg : Parental
mg+/mg : Parental
m+g+/mg : Recombinant
mg/mg : Recombinant
m+g+/mg (wild sort) and mg/mg (smaller than usual wings, garnet eyes) are the recombinants thus they were created because of the hybrid occasion.
Hence,the right answer is option 2 & 4 "wild type and miniature wings,garnet eyes"
C) Flush out the contaminants with an excessive amount of water.
Explanation:
Water is universal solvent. It dissolve many solutes inside it. Soil is contaminated with number of chemicals which is used by farmers for the controlling of pathogens. These chemicals remains on the soil for very long time. These chemicals are removed from the soil by applying high amount of water which flush out the chemicals from the soil.
The nervous system is responsible for voluntary/involuntary movement. The glands of the endocrine system produce hormones that are responsible for growth, metabolism, sexual function, etc.
