Homework Answers
Answer :
Answer is b) Curly fur is dominant over straight and yellow and red colours show incomplete dominance.
As given both male and female lions are true breeding.
Male has straight and yellow fur
Female has curly and red fur
Offsprings in F1 after crossing have curly and orange fur.
So it is clear from observation that
A) Curly dominates on straight trait
B) Since in colour expression , neither of the colour traits of parents is expressed, rather a colour in between yellow and red (orange ) is expressed .Hence it is a phenomenon of incomplete dominance.
For codominance both colours should have been expressed in same lion.

You are breeding a species of mountain lion (2n); you cross a true breeding male that has straight yellow fur with a true breeding female that has curly red fur. The offspring have curly orange fur; based on your results, what is the mode of interaction between the alleles? a. You can’t tell mode of interaction because you don’t know which offspring is a heterozygote b. Curly fur is dominant to straight fur and yellow and red fur colour show incomplete...

please answer two question below
thankyou
e) 9; 9 3. In another plant species, the presence and type of hairs on the plant are controlled by epistatic interaction between two independently assorting genes. Gene C determines whether the plant has hairs (dominant) or not (recessive); Rene D determines whether the hairs are straight (dominant) or curly (recessive). In a cross between a straight-haired plant and a curly- haired plant, 1/4 of the offspring have no hairs. 3/8 have straight hairs,...
