crossing over, process in genetics by which the two chromosomes of a homologous pair exchange equal segments with each other. Crossing over occurs in the first division of meiosis. At that stage each chromosome has replicated into two strands called sister chromatids.
Answer:
A. only prganisms that feed directly off the lost plant species will be affected:)
The correct option is (C) The eggs from the female laying 1,000 eggs have larger yolks than the yolks of the eggs from the female laying 100 eggs.
The sequence of survival and reproduction events characteristic for a member of the species is known as the life history of the species (essentially, its lifecycle).
- Natural selection drives the evolution of life cycle patterns, which are a "optimization" of trade-offs between growth, survival, and reproduction.
- The quantity of eggs laid by female fish during reproduction may vary, but it doesn't provide accurate information if the eggs from the female that lays less eggs have more yolk.
- Given that the fitness factor remains the same, the quantity of eggs laid does not necessarily correspond to the amount of yolk in the eggs.

The population of predators will increase first and then decrease slowly
It would be b. 1 TT: 2Tt: 1 tt. Because crossing two heterozygous parents means the genotypes for them are Tt and Tt. Which means that there is only one way to get TT or tt and 2 ways to get Tt
