Answer 1

A pedigree chart is most often used to

determine someone's phenotype

determine if a trait runs in a family

determine someone's genotype

manipulate genes



Horse breeders often mate horses that have special traits that they will pass on to offspring. this is an example of

Survival of the Fittest

Evolution

Artificial Selection

Natural Selection


Scientists could use genetic engineering to do all of the following EXCEPT

increase the nutritional values of plants

turn off the gene responsible for a physical defect

make a plant that is more drought tolerant

breed two animals



Genotypes are used to determine an individual's traits through a

Gene Diagram

Mendel Square

Punnett Square

Palmalt Square

Answer 3

woah...

Answer 4

1 - A pedigree chart is used to show your family tree of traits, so which one is it?

2 - Artificial Selection (We went over this earlier)

3 - B, because a scientist cannot just turn off a gene...

4 - O believe it is a Punnett Square...

5 - It is chromosomes, because there is 46 chromosomes which are paired up in twos, which make sit 23 pairs...

6 - Genotype is the details of a person you can't see, and phenotype is the details you can see

Answer 5

I believe* not O believe, xD

Answer 6

which makes it 23 pairs...* LOL all these typos.

Answer 7

@sammixboo You are wrong. We can turn off genes. This is done through either gene knockouts, DNA methylation, or creating specific RNA sequences to bind and destroy the mRNA of the gene in question. It is actually a very simple thing and is routinely done.

@hippo4 Are these questions exactly as they were asked? There things have a lot of mistakes.

Answer 8

I believe this is only 7th grade science also? I am not sure. I remember doing this lesson.

Answer 9

@sammixboo I'm not sure. I am a 5th year PhD student so I am a bit out of touch with what is being taught in high school and lower.

Answer 10

Oooohhh...

Answer 11

@sammixboo I just run around on here trying to help out.
