Use this portion of a dichotomous key for tree identification to answer the question.
Charra [1.4K]

Answer:

They are nonlobed, simple leaves and are attached oppositely on the branch.

Explanation:

A dichotomous key is a tool you use in biology to know the identity of things in nature such as trees,flowers, fish or even rocks. This key has choices that follow each other in a progressive manner, where one choice led to the other until you identify the item.In this case, to identify Dogwood, you follow the below steps;

1b. Broad leaf = Step 2

2b. Simple leaf = Step 7

7a. Leaf bases attached opposite each other on branch = Step 8

8b. Leaves not lobed = Step 9

9b. Leaves not heart shaped = Dogwood

The key is (1b,2b,7a,8b,9b)

Why human with heterozygous genotype will have the dominant phenotype?
AnnZ [28]

A human with heterozygous genotype can have a dominant phenotype if one of the alleles complete mask the effects of the other.

  • Heterozygous genotype involves two different alleles, unlike homzygous genotypes in which the alleles are the same.
  • When the two alleles of an heterozygous genotype exert equal effects on one another, they are said to be codominant.
  • When one of the alleles of an heterozygous genotype incompletely exert its effects on the other allele, it is said to be incomplete dominance.
  • When one of the alleles complete dominates and masks the effects of the other allele, it is said to be dominant.

Hence, a dominant allele will always produce a dominant phenotype even if the genotype of the organism is heterozygous.
