When the egg cell is fertilized with the sperm cell, it changes into a zygote. It then becomes a morula and blastula. Then it turns into grastula and neurula where neural plate is transformed into neural tube.. Finally, it becomes a human embryo.
Answer:
1. law of Independent Assortment; metaphase I; independent of.
2. law of Segregation; meiosis I; in separate gametes.
Explanation:
Between 1856 and 1863, Gregor Mendel developed a series of mating experiments using pea plants, which enabled the discovery of some basic principles of inheritance. These principles/laws are stated as:
1) Law of segregation: this principle states that the inheritance pattern of phenotypic traits is characterized by the presence of a gene pair and each gamete carries only one allele for each gene pair so offspring inherit one gene variant (allele) from each parent
2) Law of independent assortment: this principle states that the genes responsible for the inheritance pattern of different traits are independently sorted from one another and thereby different traits are independent one from another.
3) Law of dominance: this principle states that the dominant allele will always be expressed in heterozygous individuals (this law is only applicable in cases of complete dominance).
Answer:
It could be embreology. (I think i spelled that wrong)
Explanation:
It is a way to compare the embreos of two species to see the similarities between the two. If there are similarities then they have a common ancestor. If they don't have similarities then they arent from the same family.
