Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Aa, DD, bB, yy are all examples of
A
genotypes
B
phenotypes
Explanation: 

Detailed explanation-1: -Aa, DD, Bb, yy are all examples of genotypes. It is genetic makeup of an organism.

Detailed explanation-2: -For example, BB, Bb, bb could be used to represent a given variant in a gene. Genotypes can also be represented by the actual DNA sequence at a specific location, such as CC, CT, TT.

Detailed explanation-3: -The different types of genotypes are-homozygous recessive (pp), homozygous dominant (PP), and heterozygous (Pp). The homozygous dominant and the heterozygous genotypes show the same phenotypes.

Detailed explanation-4: -One gene is for ear size (AA or Aa being big ears whereas aa is for small ears) and the other gene is for buggy eyes (BB and Bb for buggy eyes whereas bb represents normal eyes).
