Answer:
1 out of 16 or 1/16
Explanation:
Let:
R = Round seed r = wrinkled seed
Y = Yellow seed y = green seed
Starting from the parent generation or the P generation, the genotype of the parents would be:
RRYY x rryy
This is because the cross is between a parents that are "purebred" for specific traits. This means that the parents are homozygous for the traits which in genotype form is represented by either two capital letters or two lower case letters.
Attached is the F1 generation results between a cross between the P generation.
As you can see the genotype of all the offsprings is RrYy.
Now also below is the cross between the F1 generation offsprings.
For recessive traits, it is only expressed when the dominant gene is not in the genotype, or in other words, the genotype is all in small letters. Since we are looking at two traits, you need to look for how many squares out of the total have all lowercase letters.
There is only 1 rryy out of the 16 predictions. So the answer would be 1/16.
Answer:
Glaciers picking up boulders is not a type of erosion
Explanation:
The four main types of river erosion are abrasion, attrition, hydraulic action and solution. Abrasion is the process of sediments wearing down the bedrock and the banks. Attrition is the collision between sediment particles that break into smaller and more rounded pebbles. Hydraulic action is the force of water against the banks compressing air pockets into cracks, which expand and fracture the rock over time. Solution is the process of acidic water dissolving soluble sediment.
Answer:
False.
Explanation: Fertilization is a process in sperm cell combine with egg cell.
In human beings, fertilization occurs internally. During fertilization, sperm of male combine with egg of female inside the female body which changes into zygote. After sometime, zygote turns into a new baby. About nine months, the baby comes out from the body of female.
