Answer:
D
Explanation:
This involves a dihybrid inheritance I.e. two genes are being passed on. During meiosis, specifically, the Prophase stage, homologous chromosomes (similar but non-identical chromosomes received from each parent) line side by side. According to the question, one chromosome contains A and B alleles and its homologue, received by the other parent carries a and b alleles. This means that the diploid individual has a genotype AaBb for that gene.
According to Mendel's law of independent assortment, the alleles separate independently of one another into gametes. I.e. allele A and a separates into the gametes without affecting alleles B and b of the other gene.
Crossing-over, which is the exchange of chromosomal segment occurs between the two homologues. Hence, the exchange of chromosomal segments containing alleles in the individual will possibly produce four gametes with the genotypes: AB, Ab, aB, ab.
Answer:
yes sure of it
Explanation:
Proteins are made up of amino acids that join together to form long chains. You can think of a protein as a string of beads in which each bead is an amino acid Antibodies are proteins in your blood that help protect your body from harmful invaders like bacteria and viruses. ... Without these antibodies,bacteria and viruses would be free to multiply and overwhelm your body with the disease they cause
A possible Hypothesis probably .
Embryology provides evidence for evolution because during their development, many organisms look similar, suggesting that very different organisms may have a common ancestor.
