Answer 1

1. Mendelian

2. 25%

3. 75%

4. 100

5. Tt

6. aabb

7. 56%

Answer 2

Answer 1-

Mendelian

The different allelic combinations are made by the process of mendelian inheritance. This happens before cell division.

Answer 2-

25%

In a monohybrid cross, there are four boxes, and thus each box denotes 25% share.

Answer 3-

75%

The cross between Pp and Pp will look like the image shared below. Here, PP and Pp will show dominant trait. Since, it is 3 out of 4 boxes, it will be 75%.

Answer 4-

100

The punnett square for this cross RR and WW is shown below. Since all the offsprings are RW, therefore it is 100% pink flowers.

Answer 5-

Tt

Since it is a case of dihybrid cross, the gametes formed from TtHh would contain both the alleles. The possible gametes would be TH, Th, tH and th.

Answer 6-

aabb

In any dihybrid cross with dominant alleles, the probability of getting aabb would be the least.

Answer 7-

56%

In a cross AaBb and AaBb, the probability of getting both dominant traits- round and yellow, would be 56%
