Question

a dd individual/trait is: *
a heterozygous genotype
a heterozygous phenotype
a homozygous genotype
a homozygous phenotype

from mendells first set of experiments, he concluded that: *
there are two factors controlling each characteristic he studied
of the two factors, one of the factors dominates the other factor
the two factors, separate and go to different gametes
all of the above

Explanation:

Analyze the first question

The genetic makeup \(Dd\) consists of two different alleles (one dominant \(D\) and one recessive \(d\)) for a single gene. This represents a heterozygous genotype.

Analyze the second question

Mendel's first set of monohybrid cross experiments led to several fundamental conclusions:

1. There are two factors (alleles) controlling each characteristic.
2. One factor can dominate the other (Law of Dominance).
3. The two factors separate during gamete formation (Law of Segregation).

Therefore, all of the stated conclusions are correct.

Answer:

Question 1

• a heterozygous genotype (Correct answer)
• a heterozygous phenotype
• a homozygous genotype
• a homozygous phenotype

Question 2

• there are two factors controlling each characteristic he studied
• of the two factors, one of the factors dominates the other factor
• the two factors, separate and go to different gametes
• all of the above (Correct answer)
