The answer is D. multiple alleles
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.
During the process of transcription, a portion of a DNA molecule is used to create a mRNA Molecule. DNA stores genetic information in the nucleus of your cells. When RNA molecules are produced it happens inside the nucleus. The RNA molecule can then leave the nucleus and travel to ribosomes which are located in the cytoplasm and attached to endoplasmic reticulum. The RNA will be used to create proteins molecules.
Answer: Mitochondria are present in the cells of all types of aerobic organisms like plants and animals, whereas Chloroplast is present in green plants and some algae, protists like Euglena.
