Question

question 16
which is an example of codominance?
a a homozygous black and homozygous white cow mate and produce a gray calf.
b a homozygous black and homozygous white cow mate and produce three black calves and one white calf.
c a homozygous black and homozygous white cow mate and produce three white calves and one black calf.
d a homozygous black and homozygous white cow mate and produce a black and white spotted cow.

question 17
of all the people who have studied inheritance, the person who made the most lasting impression on the science of genetics is:
a charles darwin
b robert hooke
c king george iii
d gregor mendel
e frederick griffith

Explanation:

• Question 16: Codominance is when both alleles in a heterozygote are fully expressed. In option D, the offspring shows both black and white (both parental traits) which is an example of codominance. Option A is incomplete dominance (blending). Options B and C follow Mendelian ratios (3:1) for dominant - recessive traits.
• Question 17: Gregor Mendel is known as the father of genetics for his work on pea plants and laws of inheritance. Charles Darwin is known for evolution by natural selection. Robert Hooke discovered cells. King George III was a monarch. Frederick Griffith did work on bacterial transformation.

Answer:

Question 16: D. A homozygous black and homozygous white cow mate and produce a black and white spotted cow.
Question 17: D. Gregor Mendel
