Hershey and chase performed an experiment in order to determine how bacteriophages infect bacteria and discovered that DNA is the genetic material.
<h3>
What is DNA?</h3>
This is referred to as deoxyribonucleic acid and is the genetic material of living organisms .
Hershey and chase performed an experiment using bacteriophages which contains protein and DNA by infecting it with bacteria and it was observed that DNA enters the host bacterial cell, but most of their protein does not.
This therefore means that DNA is regarded as the hereditary material.

Answer:
The correct answer would be - "aa".
Explanation:
Albinism is an autosomal recessive genetic condition which means it will be expressed only if both alleles for the pigmentation are recessive. If a single copy of the dominant allele present with the recessive allele the expression of the recessive allele would be masked by it and skin will be pigmented however they will act as carriers of the condition.
There would be three condition or three allele combination:
AA - no recessive allele so no albinism
Aa - dominant allele with recessive allele which means carrier but pigmented skin
aa - both alleles are recessive so the albinism will be expressed.
Answer:
Legume crops improve soil health, they add nitrogen and organic matter to the soil and reduces potential erosion and leaching loss. Legumes may reduce the energy footprint of cropping systems by reducing the need for nitrogen fertilizer, and improve the stability and health of agro-ecosystems.
