The question is incomplete. The complete question is:

Indicate if the conditions described would result in the development of a male or a female individual. SRY is a gene on the Y chromosome that is involved in initiating the development of the male phenotype in humans.

a) Only one X chromosome  

b) One X chromosome and a Y chromosome with the SRY gene deleted

c) One normal X chromosome and an X chromosome with an SRY gene insertion

d) Two X chromosomes and a Y chromosome

e) An individual with only one X chromosome and a Y chromosome with an SRY gene mutation

f) Four X chromosomes and a Y chromosome

g) One each of the X and Y chromosome

a) Only one X chromosome = FEMALE

b) One X chromosome and a Y chromosome with the SRY gene deleted = FEMALE

c) One normal X chromosome and an X chromosome with an SRY gene insertion = MALE

d) Two X chromosomes and a Y chromosome = MALE

e) An individual with only one X chromosome and a Y chromosome with an SRY gene mutation = FEMALE

f) Four X chromosomes and a Y chromosome = MALE

g) One each of the X and Y chromosome = MALE

Explanation:

The SRY gene is present on the Y chromosomes of human males and serves as one of the major determinants of sex in humans. The SRY gene regulates the development of testes in the fetus. The release of testosterone from developing testes then results in the development of other male characteristics. The absence of SRY genes or the presence of a nonfunctional SRY gene would result in the development of the fetus into a female child.

Therefore, human females have two X chromosomes as the sex chromosomes and the human males have functional SRY gene present on their Y chromosomes. Insertion of the functional SRY gene to the X chromosome of the fetus would result in its development into a male child irrespective of the absence of the Y chromosome in it.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.    

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
