Hi
The answer is : Evangelista Torricelli
I hope that's help:)
1.Amniocentesis is a procedure which involves draining a small amount of amniotic fluid. Amniotic fluid contains a few cells from the fetus. Chromosomes in the cells, which contain the genetic information of the fetus, are examined for abnormalities
2. DNA testing, introduced in 1976, is used to identify specific gene disorders.
1. Carnivore- a flesh eating animal
2. Producer- any green plant that traps the suns rays and converts them to chemical energy
3. Herbivore- an animal that feeds on plants
4. Food web- the linear feeding patterns of organisms between trophic levels
5. Omnivore- an animal that eats both plants and animals
6. Food chain- the feeding of organisms on other organisms in more than one trophic level
Answer:
A homozygous recessive pea plant would have genotype rr and the heterozygous plant would have genotype Rr. So after the crossing between these two individuals occurs the two offspring produced would be heterozygous and the other two would be homozygous recessive.
R r
r Rr rr
r Rr rr
Therefore the genotype ratio would be 1:1 and the phenotypic ratio would also be 1:1 in the F1 generation because half would be round and half would be wrinkled.
