Question

13 multiple choice 1 point analysis question: which offspring could not arise from the parent cells with the chromosomes shown below? assume crossovers can occur between chromosome pairs in the parent cells. allele key dominant c - curly wing b - brown body l - legs on head r - red eyes recessive c - normal wing b - black body l - antenna r - orange eyes

Explanation:

To determine which offspring could not arise, we need to consider the alleles present in the parent chromosomes and the possibility of crossovers. Offspring inherit alleles from their parents. By examining the allele - key and the phenotypes of the offspring, we can identify if the combination of alleles is possible given the parental chromosomes. If an offspring has a phenotype with alleles that are not present in either parent (even considering crossovers), it cannot arise from these parents.

Answer:

(Without seeing the actual allele combinations in the offspring options, we cannot definitively choose an answer. But the general approach is to check for non - parental allele combinations). If we assume the options are as follows based on the phenotypes described in the allele - key:
A. Offspring with a phenotype that has an allele not present in either parent's chromosomes (after considering crossovers) could be the answer.
B. Similar check for each option to see if the allele combination is possible from the parents.
C. Similar check for each option to see if the allele combination is possible from the parents.
D. Similar check for each option to see if the allele combination is possible from the parents.

We need more specific information about the allele combinations in each offspring option to accurately choose the one that could not arise from the given parents.
