Answer 1

Answer #1

In qq:RR, the flowers produced are yellow. R is dominant here for producing yellow colour.
In QQ:rr, the flowers produced are pink. Q is dominant for producing pink colour.
InQQ:RR, the flowers produced are orange . Here both dominant alleles Q and R are responsible for producing orange flowers.
The first possiblity of producing orange flowers is correct.

QQ X RR

Q Q

R QR QR

From the above, it is proved that the offsprings produced are in equal ratio which gives orange flowers

3B. In bougainvillea (a tropical plant), the q/q; R/R genotype results in yellow flowers, and the Q/Q: r/r genotype gives pink flowers. Wild-type flowers are orange and are observed in plants with genotype Q/Q; R/R. Two possibilities have been proposed for the biosynthetic pathways of flower color: 1. yellow pigment → pink pigment → orange pigment OR 2. red pigment → pink pigment → orange pigment a) Propose a genetic experiment that can determine which of the two possibilities is...

Genetics Experience Please The R locus determines flower color in a new plant species. Plants that are genotype RR have red flowers, and plants that are rr have white flowers. However, Rr plants have pink flowers. What type of inheritance does this demonstrate for flower color in these plants?

Question 2b) You are studying a flowering plant that produces remarkable bright green flowers in its wild type. Your colleagues have discovered two new mutant lines of this plant. One new line breeds true for a yellow flower color. Another new line breeds true for a blue flower color. Your group does the following crosses and makes these observations: yellow X green ⇒ F1 is all green ⇒ F2 75% green and 25% yellow blue X green ⇒ F1 is...
