Answer:
A. I think A is the answer.
Explanation:
Dad: TtBb
Mom: ttbb
You have to use distribution for dihybrid crosses. Meaning, the first allele of each trait has a equal chance of being paired with the other allele of the other trait. So for example with Dad, I will number the traits:
T(1)t(2)B(3)b(4)
To set up the possibilities from Dad, it would be 13, 14, 23, 24: TB, Tb, tB, tb. Same idea goes for Mom, except since all alleles are the same, you only need to make one column for Mom, since if you did all 4, the other 3 would just be repeats of the 1.
Cross:
tb
TB TtBb
Tb Ttbb
tB ttBb
tb ttbb
The phenotypic ratio is 1 Tall Brown: 1 Tall Blue: 1 Short Brown: 1 Short Blue
Answer:
The correct answer is - to produce recombinant that leads to genetic variation.
Explanation:
Random shuffling or random alignment of the chromosome during gamete formation allows the formation of new allele combinations. In the crossing over the parts of the homologous chromosomes are switched between homologous and recombinants are formed that shows are genetic variation.
So, now they have different allele combinations and chromosome combinations as well. Random shuffling does not provide genetic variations as crossing over
