Question

part a the syntenic genes a and z are linked. a cross between two parents, aazz and aazz, produces f1 progeny with the aazz genotype. what are the possible arrangements of alleles on the f1 progenys chromosomes? aa/zz az/az or az/az az/az az or az az/az incorrect; try again; 5 attempts remaining submit previous answers request answer provide feedback next >

Explanation:

Step1: Analyze parent genotypes

Parents are AAzz and aaZZ. Since A and Z are linked, the gametes from AAzz will be Az and from aaZZ will be aZ.

Step2: Determine F1 genotype formation

The F1 genotype AaZz is formed by the combination of Az and aZ gametes. The possible arrangements of alleles on F1 progeny's chromosomes are AZ/az (cis - configuration) and Az/aZ (trans - configuration).

Answer:

AZ/az or Az/aZ
