hello everyone let's start the question the questions that which of the following represent a test for capital w small w crosses with capital w Capitol w capital w small w crosses with capital w small w capital w small w crosses with small w small w capital w Capitol w crosses with capital w Capitol w is asking about test this text or it is made between two parents it is made between two parents having unknown genotypes are unknown recessive gene which means that the stresses of genotype it is not expressing itself in the presence of dominant not found any expression in presence of dominant and it is denoted by the small letter of the alphabet with hair
it is capital w small w interested with capital w capital w is the success of no this is not a test because this is heterozygous dominant and hear this is homozygous dominant to both parents are dominant here it is not a test for because test of is made between recessive gene type of a parent is a second option which is capital w small w when process capital w small petrol dominant again both the parents is also not a test for ABC capital w small w crosses with small w small w then this is a test this is a test cross Vikas this is heterozygous dominate but this is our
touch what if we see the other option which is for which is capital w capital w crosses with capital w Capitol w so they both are dominant this is also not test for police advanced test cross and significance of test process it is used to identify the type of the Anmol ka ok significance of the text from under the correct answer will be option third which is capital w small dablu crosses with small w small dubbing
