<h2>Maternal effect</h2>
Explanation:
In maternal effect the phenotype of the progeny is decided by the genotype of the mother
- The female partner is one step ahead to her male partner
- The ovum transcribes some of its nuclear genes prior to fertilization and these genes are responsible for the development of embryo that is why these genes are called maternal effect genes
- This effect is observed in Drosophila
In the given question both male and female have brown eyes with Nn genotype,phenotype of the offspring will be decided by the genotype of mother(Nn) hence despite of having recessive genotype(nn) all the offsprings will show brown eyes
Answer:
D.both A and B
Explanation:
because if there some option,like abcd and the letter d. is both a and b that is the correct answer.
Genotypes are the genetic composition of the organism. The alleles for the genotype are located at the genetic loci of the chromosome inherited from each parent.
<h3>What are alleles and genetic loci?</h3>
The alternate version of the genes that code for the hereditary trait and characteristic of the organism giving them the genotype and the phenotype is the alleles.
Genetic loci is the designated position found on the chromosome of the organism possessing the alleles coding for the genotype that can be purebred dominant and recessive, and heterozygous.
Therefore, alleles are physically present on the loci.

The "community
acquired" penicillin resistant S. aureus originated from the hospital since
1940’s based on the graph and after 10 years, S. aureus resistant increases to 60%.
In 1960’s, it spread to the community and eventually spread across the world.
Moreover, Staphylococcus<span> aureus infections <span>can
be treated with penicillin in the past but when it became resistant to penicillin, pharmaceutical companies discovered methicillin,
which is a derivative of penicillin. However, </span>S. aureus resistant was also develop with methicillin from late 1980’s
in the hospital and in the community from the start of year 2000.</span>
