In the garden pea, tall vine (D) is dominant over dwarf (d), green pod (Y) is dominant over yellow (y) and round seed (W) is dom

siniylev [52]

Answer:

3/8 tall, green, round

3/8 dwarf, green, round

Explanation:

<u>The progeny which are in highest ratio represent parental plants.</u>

Here in the given question, 3 out of 8 progeny are tall, green, round and 3 out of 8 progeny are dwarf, green, round which are the highest in number so they represent parental plants. The reason behind this is that during crossing over only two non-sister chromatids undergo crossing over while two other parental chromosomes remain intact. Out of the 4 chromosome types, 2 remain the same which will result in the same type of genotype of off-springs as of parents. So even if there is 100% chance of crossing over between non sister chromatids still only 50% will be recombinants rest of the 50% will represent parental type.

Another case may be when two genes are very near to each other then it is quite possible that the genes may not undergo crossing over at all in that case there will be no recombinants at all.

So, it simply means that parentals > recombinants or the progeny which are highest in number represent parentals.

In case of unlinked genes, parentals = recombinants. But, <u>recombinants can never be greater than parentals.</u>

A pea plant is heterozygous for both seed shape and seed color. S is the allele for the dominant, spherical shape characteristic

So, you would make a punnet square. You would put the capital S and lowercase s on the top of it and then the capital Y and lowercase y on the side. Then you should have SY, sY, Sy, and sy as your outcomes.

Mistletoe is a green plant that can make its own food, but also derives food from the mesquite tree on which it lives. In this w

Natali5045456 [20]

Answer:

1. Mistletoe is parasitic to the mesquite tree, it steals from the tree without giving anything valuable back to it. In this case, only the mistletoe gains an advantage.

2. If the mistletoe population on the tree were to increase, the mistletoe would probably end up slowly killing the tree. I say this because its a parasite to the tree. Its constantly stealing water and valuable minerals that it needs and doesnt give back anything that could help the tree. With all the water and minerals being stolen and an uneven rate with no way for the tree to replenish it all quickly enough it'll die.

3. Its parasitic since the mistletoe just takes and takes harmfully
