If one parent is heterozygous white (ww) and the other is homozygous black (ww), give the phenotype and genotype ratios for this cross.
phenotype:
a. 1/3 black ; 2/3 white
b. 1/2 white ; 1/2 black
c. 3/4 white ; 1/4 black
d. 2/3 black ; 1/3 white

genotype ratio ww: ww
a. 2: 1
b. 1: 2
c. 1: 1
d. 3: 1

Option B, 1/2 white ; 1/2 black

Genotype ratio Ww:ww

Option C, 1:1

Explanation:

Given –  

First parent is heterozygous white  with genotype Ww

Second parent is homozygous black (ww)

If these two parents are crossed each other , the following offsprings are produced –  

Ww

wWwww

wWwww

The genotype of Ww is white in color

The genotype of ww is black in color  

Thus there are ½ white and ½ black  

Genotype ratio –  

Ww: ww

2: 2

1:1

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.  

the answer is d p: cell, q: organ, r: organ system, s: tissue
