You decide to mate two Hebridean Black Dragons (yes from Harry Potter fame). The female is black with rough scales (though her mother had smooth scales) and purple eyes. The male is green (though his father was black) with smooth scales and yellow eyes (his father had purple eyes). Green color, Rough scales, and Yellow eyes are dominant.

a. What are the genotypes of the parents? be specific

b. What is the probability of having a female dragon that is completely recessive for all traits?

Expert Solution

Let ' G ' be the dominant allele responsible for the green colour and let ' g ' be the corresponding recessive allele responsible for the black colour.
Also, let ' R ' be the dominant allele responsible for the rough scales and let ' r ' be the corresponding recessive allele responsible for the smooth scales.
Also, let ' Y ' be the dominant allele responsible for the yellow eyes and let ' y ' be the corresponding recessive allele responsible for the purple eyes.

a) Now, the genotype of the parents -
The genotype of the male parent = GgrrYy
The genotype of the female parent = ggRryy

b) Their cross to produce F1 offsprings -

You decide to play a simplified version of blackjack where you are dealt two cards from a well-shuffled deck of 52 cards. One of the cards is dealt face down and one of the cards is face up. Assume that all of the cards count for their face value (e.g., a 3 of hearts = 3), face cards (J, Q, K) count as 10, and aces [always] count for 11^(1) The value of a player’s hand is determined by the...
