In humans tongue rolling is dominant to the inability to tongue roll. if a heterozygous tongue roller and a non-tongue roller have a child, what are the chances the child will be a non-tongue roller? a. 0 b. 0.25 c. 0.5 d. 0.75

The chances of a child being non - tongue roller is

Explanation:

Let the allele for dominant "tongue rolling trait" be represented by "T"

The allele for recessive  "non-tongue rolling trait" be represented by "t"

The genotype of a heterozygous tongue rolling parent will be "Tt"

The genotype of a homozygous non- tongue rolling parent will be "tt"

If a cross is carried out between these two individuals , the offspring  produced are as shown in the punnet square below-

Tt

tTttt

tTttt

So the number of offsrpings which are non- tongue roller are two in numbers represented by "tt"

So the chances that a child will be a non-tongue roller are

Where , "4" represents the total number of offsprings produced

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
