Answer:
1) RR x rr
2) Shown below
3) 100% Rr with red eyes
4) Punnett square shown (Rr x Rr)
5) 25% of the offspring are h0m0zygous dominant with red eyes (RR), 50% are heterozygous with red eyes (Rr), and 25% are h0m0zygous with brown eyes (rr)
Explanation:
Let's say the allele for red eyes is R and the allele for brown eyes is r.
1. A cross between a h0m0zygous dominant (two copies of the dominant allele, R) and h0m0zygous recessive (two copies of the recessive allele, r) is: RR x rr
2. R R
r <em>Rr Rr</em>
r <em>Rr Rr</em>
<em />
The F1 generation is shown in the Punnett square above.
3. The F1 generation are 100% Rr. They are heterozygous. Since red (R) is dominant, the rats all have red eyes
4. A cross between the F1 generation (Rr x Rr) gives the F2 generation
R r
R <em>RR Rr</em>
r <em>Rr rr</em>
<em />
5. 25% of the offspring are h0m0zygous dominant with red eyes (RR), 50% are heterozygous with red eyes (Rr), and 25% are h0m0zygous with brown eyes (rr)
Answer: Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.
Answer: Charles Lyell inspired Darwin.
Explanation:
Charles Lyell was a Scottish geologist born in 1797 at kinnordy. He was friend to some scientists. He was a friend to Charles Darwin. He questioned the ideas of different geologists. Charles Lyell debunked the Earth is 6000 years ago which was proposed by some Bible scholars. He stressed that the Earth took long time to formed. He said that erosion give the Earth it's shape. He was termed heretic during his time because of His findings.
Answer:
100% pink flowers
Explanation:
If neither allele is dominant, it will create incomplete dominance. So the offspring will neither be red nor white, the offspring will be pink.
