Question

The allele (AA, Aa, or aa) combinations are achieved through what process?

Answer 1

1. meiosis
2. 25%
3. 75%
4. 100%
5. Tt
6. aabb
7. 25%

Answer 2

1. Meiosis : During prophase of meiosis I, crossing over occurs which results in intermixing of genes between parent.

2. 25 %. In monohybrid cross, offspring produced in phenotypic ratio 3:1. ( 4 offspring, each have 25 % )

3. 75 %. In monohybrid cross, offspring produced in phenotypic ratio 3:1. 3 (75 %) with dominant trait and 1 (25%) with recessive trait.

4. 100%. In incomplete dominance all the offspring produced in F1 generation is neither dominant nor recessive. in this case all offspring will be pink.

5. Tt. Both the alleles T and t will segregate independently.

6. aabb. it will be the rarest combination.

7. 56%. 9 out of 16 seeds produced in the ratio 9:3:3:1 will be round and yellow.
