Question

Plants with genotypes RRTT and rrtt were mated to produce an F1 plant. The F1 plant was testcrossed to a plant with genotype rrtt. Following are the numbers and types of progeny from this testcross:

38 RrTt

42 rrtt

8 Rrtt

12 rrTt

Answer 1

Q1) Which of the following is a recombinant-type offspring?



Answer
a.
RrTt
b.
rrTt

Q2) How can you tell that the R and T genes are on the same chromosome?
Answer
a.
The number of parental and recombinant-type offspring are equal.
b.
There are more parental-type offspring than recombinant-type offspring.
c.
There are more recombinant-type offspring than parental-type offspring


no idea what I'm doing.

Answer 3

answer to the question 1 will be RrTt

Answer 4

answer to question 2 will be option b

Answer 5

are you sure? I'm in his class also?

Answer 6

we have 2 more questions acually if you could help us out. Let me post on another thread.

Answer 7

yes i am..
A genotypic recombinant is an offspring with a genotype different than both parents

Answer 8

If two genes are on same chromosome then there will be less crossing over and thus parental or wild characters will be more

Answer 9

@Abhisar Actually Q1 = B. That would be the recombination type.
