nebula

Why are fossils considered to be so rare?
lucky conditions need to be met- The dead organism must be protected from scavengers, microorganisms and the processes of weathering (usually this means the body is quickly covered by sediments)

If a homozygous recessive pink hair bunny mated with a heterozygous ginger hair bunny what is the percentage of them having a bunny with pink hair?
- Pink hair is recessive → use g
- Ginger hair is dominant → use G
The parents are:
- Homozygous recessive pink bunny = gg
- Heterozygous ginger bunny = Gg
Cross:
gg×Gggg \times Gggg×Gg
Possible offspring:
- From gg parent: only g
- From Gg parent: either G or g
Punnett square results:
- Gg = ginger hair
- gg = pink hair
So the offspring are:
- 50% Gg (ginger)
- 50% gg (pink)
Answer:
- 50% gg (pink)

What is the difference between Analogous & homologous structures?
Analogous:
Different ancestors, Different underlying structures
Homologous:
Same ancestor/Same underlying structures
