Answer:
Same phenotype but different genotype is possible due to presence of dominant allele
Explanation:
A person can have a dominant allele on both the homologous chromosomes while another person may have single dominant allele and a corresponding recessive allele.
Is spread from one person to another through a variety of ways that include: contact with blood and bodily fluids; breathing in an airborne virus; or by being bitten by an insect.
DNA sequencing technique runs through database so it can compares all the sequenced information and finds similarities.
Answer:
Option-A
Explanation:
Fertilization refers to the fusion of the male and female gamete to form the zygote.
When the fertilization occurs inside the organism through insemination then it is known as the internal fertilization and when it occurs outside the organism like observed in the amphibians when male and female gametes fuse in the water is known as external fertilization.
Both are different type of fertilization but share a similarity that is the formation of a single cell called the zygote which grows into the embryo by the mitotic division. The embryo later develops into the organism.
Thus, Option-A is correct.
