Agene that has two alleles, a and a, is located on the same chromosome as a second gene that also has two alleles, b and b. suppose a diploid individual has alleles ab on one copy of this chromosome and alleles ab on the other copy of this chromosome. for this individual, select the pair of recombinant genotypes that could result if crossing over occurs between these two chromosomes.1. ab and ab2. ab and ab3. ab and ab4. ab and ab

The correct answer is option 3. "Ab and aB".

Explanation:

Crossing over of two chromosomes, or chromosomal crossover, is the exchange of genetic material between two homologous chromosomes. This genetic process is responsible for the genetic variations that occurs during sexual reproduction. Usually crossing over occurrs between matching genetic sequences, therefore a diploid invidual with an AB allele that crosses over with an invidual with ab allele will exchange each allele in equal parts. The resulting chromosomes will be Ab and aB, one part per allele.

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.

not too sure but maybe in the hot springs.
