While carbohydrates supply immediate energy for the body, lipids — a class of macromolecule — provide long-term energy storage. Lipids, more commonly known as fats, appear in many foods.
The fossil record gives evidence of extinct species. The fossil record shows that organisms always remain the same. Which best describes how the fossil record is
I think I understand even without the picture. I'll add a picture of the Punnett Square filled in, but what you're crossing is
Tt x tt (heterozygous crossed with a homozygous recessive)
The ratio you get in the end is 2 heterozygous (Tt) and 2 homozygous (tt) offspring, so the ratio is 1:1.
So the percentage of offspring that are homozygous recessive is 50%.
Answer:
Heterozygous A: AO (remember, O type blood is a recessive allele. It's masked by A)
Heterozygous B: BB (h0m0zygous)
AO x BB --> AB, BO
Therefore, the genotypes of their offspring will be 1 AB to 1 BO, while the phenotypes will be 1 AB blood to 1 B blood.
I hope this answer helps you find what your looking for! :)
