Feather colour in parakeets is controlled by two genes. Blue colour (B) is dominant over absence of colour (b). Yellow colour (Y) is dominant over absence of colour (y). When a B allele and a Yallele are present, a green parakeet is produced. The probability of obtaining a female or male parakeet is the same as for humans. What is the probability of obtaining a male green parakeet when a green parakeet heterozygous for both genes is crossed with a white parakeet? Select one: a. 0.75 b. 0.25 c. 0.13 d. 0.50

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.
