Feather color in budgies (parakeets) is determined by two different genes, Y and B. YYBB, YYBB, or YYBB is green; yyBB or yyBb is blue; YYbb or Yybb is yellow; and yybb is white. Two blue budgies were crossed. Over the years they produced 22 offspring, 5 of them were white. What are the most likely genotypes of the two parents? Multiple Choice Both were yyBB One is yyBb and the other is yybb Both were YYBB Both were yyBb One is yyBB and the other is yyBb

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
