1. In dogs, wire hair (S) is dominant to smooth hair (s). In a cross of a heterozygous wire-haired dog with a smooth haired dog, what will be the phenotypic and genotypic ratios of the F1 generation? Use the Punnett square provided to show your results.

The genotypic ratio of the F1 generation is:

1:1 OR 50% heterozygous wire-haired, 50% homozygous smooth-haired.

The phenotypic ratio of the F1 generation is:

1:1 OR 50% wire-haired, 50% smooth haired.

Explanation:

A cross between the parents with genotype:

Parent 1; Ss and Parent 2; ss, will yield two types of progeny. Half the offspring in the F1 generation will be heterozygous wire-haired just as in parent 1, while the other half will be homozygous short-haired as in parent 2.

Demonstrating it with a punnet square:

             S                     s

s            Ss                  ss

s           Ss                   ss                                  2/4 offspring: Ss,

                                                                        2/4 offspring: ss

Since the allele for wire hair is dominant over that of short hair, the presence of one dominant allele, translates into the offspring having wire hair phenotypically or by physical assessment. The offspring who are homozygous for the recessive allele however, express short hair because they carry both alleles for short hair.

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.
