Answer:
The correct answer is "exchange of genetic information between parental chromosomes".
Explanation:
Homologous recombination is a genetic recombination that occurs when two similar or identical molecules of DNA exchange some of its nucleotide sequences. This type of recombination is most widely used for DNA repair purposes, however this is not distinctive of eukaryotes as prokaryotes use it as well. Therefore the most significant an unique role of homologous recombination in eukaryotes is the exchange of genetic information between parental chromosomes. This particular function is known as chromosomal crossover and it is only found in eukaryotes.
Answer:
AB, aB, Ab
Explanation:
Man has blood type B so could be BB (homozygous dominant) or could be Bb (heterozygous)
Woman has blood type A, so she could be AA (heterozygous dominant) or Aa (heterozygous)
Now, we need to make a separate cross for woman with AA, man with BB and we get children of all AB
Then we can make another cross for genotypes Aa and BB, and we get AB and aB
We can continue this for AA,Bb and for Aa,Bb
Answer:Genetic engineering, also called recombination DNA technology, involves the group of techniques used to cut up and join together genetic material, especially DNA from different biological species, and to introduce the resulting hybrid DNA into an organism in order to form new combinations of heritable genetic material.
Explanation:
Answer:
3 alleles is the correct answer . Blood types = A , B , AB and O .
Explanation:
Human blood type is determined by codominant alleles. There are three different alleles, known as IA, IB, and i. The IA and IB alleles are co-dominant, and the i allele is recessive. The possible human phenotypes for blood group are type A, type B, type AB, and type O.
