Answer:
A and a
Explanation:
GAMETE formation occurs via a process called MEIOSIS. During meiosis, segregation and independent assortment of genes occur. According to Gregor Mendel who proposed the law, the law of segregation states that the alleles of a Gene will separate into gametes. This separation occurs in such a way that only one allele of that gene is found in each gamete.
In this case, an organism with genotype "Aa" will produce gametes that contains the following: A and a. Therefore, the gametes of genotype Aa will be A and a.
Nitrofurantoin is antibiotic drug commonly used to treat urinary tract infections in pregnant women because of its safety and effective use (the body quickly filters it out). It is not recommended to be used in late pregnancy due to the potential risk of hemolytic anemia in the newborn.
But, recent studies suggested that there is a possible association between congenital malformations following exposure to nitrofurantoin during the first trimester of pregnancy.
fertilization comes first
it is followed by cleavage which is the rapid cellular division which forms the blastula
then comes gastrulation where the 3 germ layers are formed.
followed by organogenesis which consists first forms the organs and then comes the specialization
Therefore your answer would be B
