The correct answer is option B, that is, a dentist surveying patients about toothpaste preference.

Convenience sampling refers to the non-probability technique of sampling where the subjects are chosen due to their suitable availability and propinquity to the researcher. This type of sampling method is dependent upon the collection of data from the members of the population who are conveniently accessible to take part in the study.

In one type of plant, orange petals (O) are dominant over yellow petals (o) and tall stems (T) are dominant over short stems (t)

vodka [1.7K]

Answer No 1:

The set up of the punnet square is shown in the attached diagram. As the alleles assort independently hence the gametes formed will be OT,Ot,OT,Ot and OT,Ot,oT,ot. These will be the outcomes of the possible gametes formed. When these gametes are cross bred, the results are shown in the diagram attached.

Answer No 2:

The outcomes of each possible genotype are:

OOTT = 2/16

OOTt = 4/16

OOtt = 2/16

Oott = 2/16

OoTT = 2/16

OoTt = 4/16

Answer No 3:

Orange petals with tall stem and orange petals with small stems present in ratio 12:4 i.e. 3:1.
