Question about Mendel's principle?

Question

I really don't get this question. HELP please! x] thxx

Q: Mendel's principles state that each trait is coded for by two allels. And that the alleles segregate when gametes are formed. Show what that means in a diagram.

Answer 1

use a punnet square use the females alleles on top and the males on left, then put them together.
B b
b Bb bb
b Bb bb

Get it?

Answer 2

Just show a parent genotype with two alleles.
Then put the gametes underneath the parent genotype with each letter in a separate circle. Draw arrows from the parent genotype to each circle to show that the alleles separated (segregated).

P Bb

g B b

P stands for parents.
g stands for gametes.
Circle each gamete and draw in the arrows.

Answer 3

ok, im no longer likely to repeat this of websites and all that, yet ill attempt to do my superb, which i learnt it mendel's regulation of independant sequence grew to become into that each and each pair of alleles separates into gammetes with the aid of themselves. in case you kno what the 9:3:3:a million ratio is, that's the genotype opportunities ratio heres an occasion. Say you have the gene to be bald as ressevie, and furry? to be dominant, and blakc hair colour is dominant...whcih it relatively is, and blonde is recessive... So furry=H Bald=h Black Hair=B Blonde=b So the mum and dad could have 2 characters for each gene, like HHBB HhBb HHbb hhBB hhbb they're going to produce gametes like this, take HhBb as an occasion HhBb---- HB, Hb, hB, hb, then you jsut draw your greater punnet sq....and remedy.
