Life and 98% of what you learn is a waste
Your answer would be D. The possible combinations of alleles in offspring based on the parents genetic makeup. The punnet square is basically used to determine what the outcome of an offspring would be.
Answer:
An oil spill, fertilizer run off, and another thing i could think of is a flood hope this helped :)
Explanation:
Flowering plants reproduce sexually through a process called pollination. The flowers contain male sex organs called stamens and female sex organs called pistils. Cross-pollination happens when the wind or animals move pollen from one plant to fertilize the ovules on a different plant.
C = dominant
c = recessive (cystic fibrosis)
CC, cc = homozygous (homo = same)
Cc = heterozygous (hetero = different)
Recessive traits are expressed only when two recessive alleles are present
If you get CC, you will not have cystic fibrosis. (<span>c </span>is the cystic fibrosis allele)
This person would be homozygous dominant and would not pass on the disease because they do not have any cystic fibrosis alleles.
If you get<span> Cc</span> you will not have cystic fibrosis b/c the<span> C</span> is dominant and overrides the cystic fibrosis allele c.
This person would be heterozygous and, though they do not have the disease, they would still have a chance of passing on the disease because they carry the cystic fibrosis allele.
If you get cc you will have cystic fibrosis b/c c is the cystic fibrosis allele and it is not being overridden by a dominant allele.
This person would be homozygous recessive.
