Prove using a punnett square that two blue eyed people can not have a brown eyed child

Biology
1 answer:
ra1l [238]3 years ago

So considering B is for dominant Blue eye and b is for recessive brown eye;

Now the possible combinations which will ensure a blue eyed person will be BB or Bb but never bb.

So using the square for BB and Bb

       B        B

B      BB     BB

b      Bb     Bb

All the above combinations would make all children have blue eyes BUT 2 children would also have brown eye colour as a recessive allele which could effect the next generation.

I can't be 100% sure because of not reading the actual question but this is my best guess.

Answer:

Just before the cat drops, it was stationery. Therefore it has energy of position called  potential energy.As it drops, the Gravitational potential energy is converted to Kinetic Energy,The conversion mid- air is P.E to K.E to P.E to K.E to P.E to K.E, until it touches the ground. As it touches the  ground all the energy is converted to P.E energy of position.

As it runs after mouse the P.E is converted back to Kinetic , energy of motion. As it feeds on the mouse , the chemical energy obtained  as protein from mouse meat.This is later converted back to Mechanical energy as (kinetic and Potential  energy)   in the cat.

How does genetic variation and environmental factors work together to cause natural selection?
Norma-Jean [14]

_______________, harmful or helpful, is considered to be the source for new alleles and a main contributor to the diversity of l
ololo11 [35]

The right answer is A mutation.

Alteration of the genetic material (DNA or RNA) of a cell or virus that causes a change in certain traits due to the inheritance of this genetic material from generation to generation.

Abnormal modification of the DNA of a gene, either spontaneously during cell division, or under the influence of external agents called mutagens. This gene is modified to be transmitted to the daughter cells. Some mutations have no effect on the cell. Others are the first step in a long process of cancerization.

Rare are the mutations that are beneficial.
