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:
B. The chromosomes exchange genetic information.
Explanation:
Crossing over of tetrads during meiosis is very important for the exchange of genetic information.
This step of meiosis allows for each chromosome to be genetically unique and distinct from the others, creating genetic variation.
Crossing over does not double the number of chromosomes or reduce the number. The number of chromosomes stays the same.
So, the correct answer is B. The chromosomes exchange genetic information.
