Answer 1-
<u>Mendelian </u>
The different allelic combinations are made by the process of mendelian inheritance. This happens before cell division.
Answer 2-
<u>25% </u>
In a monohybrid cross, there are four boxes, and thus each box denotes 25% share.
Answer 3-
<u>75% </u>
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-
<u>100 </u>
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-
<u>Tt </u>
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-
<u>aabb </u>
In any dihybrid cross with dominant alleles, the probability of getting aabb would be the least.
Answer 7-
<u>56% </u>
In a cross AaBb and AaBb, the probability of getting both dominant traits- round and yellow, would be 56%
