In organisms with large genomes, inversions are more likely to be tolerated if the breakpoints occur in: reciprocal translocatio
andre [41]

Answer:

Non-coding DNA.

Explanation:

Inversion is a type of chromosomal abnormality in which the sequence of a segment of a chromosome is inverted or rotated at an angle of 180 degrees.  This type of abnormality can change the reading frame of the gene and can cause mutations.

But if the genome sequence is non-coding that is not involved in the formation of protein synthesis than even if the reading frame is inverted will not affect the phenotype of the cell. Also, the non-coding sequences are removed by the splicing mechanisms.

Thus, Non-coding DNA is correct.

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
