The allele for an attached earlobe is recessive. in the third generation, what are the odds that a carrier father and homozygous dominant mother will have a child with an attached earlobe?
a. 0 %
b. 25 %
c. 50 %
d. 100 %

The correct answer would be A. 0%

Let A and a be the dominant and recessive allele of the gene responsible for the attachment of earlobes respectively.

The father is a carrier of the trait. Thus, the genotype of the father would be Aa.

Similarly, the mother is homozygous dominant due to which her genotype would be AA.

The cross would produce the offspring with two types of genotypes which are Aa and AA.

Thus, none of the offspring would have attached earlobes as it is recessive trait.

explanation:

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.
