In 1809, prominent naturalist Jean-Baptiste Lamarck proposed a theory for the evolution of species. According to his theory, whi

ch was known as transmutation of species, organisms gain physical traits during their lives that allow them to adapt to their environments. These organisms then pass their acquired physical traits down to their offspring. This process, according to Lamarck's theory, explains the way in which species have become adapted to their environments. Which of the following observations most likely demonstrated the inaccuracy of this theory?

The answer is: Organisms will not pass acquired physical traits to the next generation.

In his theory, Lamarck proposed how species adapted to the changed environment by passing down <span>acquired physical traits to the next generation. But, after Charles Darwin published his theory of evolution, Lamarck's theory was rejected. Now, it is known that acquired physical traits could not be inherited and epigenetics is a good proof for that.</span>

This tutorial will take you step by step through the question. Individuals with the genotypes Aa Bb CC Dd and Aa bb Cc Dd are cr
Mrac [35]

Answer:

The correct answer is -

a) 1/16

b) 1/64

c) 1/32

Explanation:

According to the law of independent assortment, each allele of a particular gene has equal chances of getting inherited into the gametes.

In a Mendelian cross of Aa x Aa would give;

AA = 1/4,

Aa = 2/4 and

aa = 1/4

The result of the cross between AaBb x AaBb would be 1/16 due to the fact that probability is still the same AA = 1/4, BB = 1/4 therefore, AABB = 1/16 = 1/4× 1/4.

Now based on this crossing the following:

AaBbCCDd x AabbCcDd.

Take each allele as individual

Aa x Aa would give; AA = 1/4, Aa = 2/4 and aa = 1/4

Bb x bb would give; BB = 1/2, bb = 1/2

CC x Cc would give; CC = 1/2, Cc = 1/2

Dd x Dd would give; DD = 1/4, Dd = 2/4 and dd = 1/4

Then the probability of progeny of the following would be:

a) the probability of AaBbCcDd = 2/4 x 1/2 x 1/2 x 2/4 = 1/16

b) the probability of aabbCCdd = 1/4 x 1/2 x 1/2 x 1/4 = 1/64

c) the probability of AabbCcDD = 2/4 x 1/2 x 1/2 x 1/4 = 1/32

A) a large group of cells that grew without regulation.

A tumor is where there is a mutation that causes cells to lose their ability to self regulate, so they reproduce too fast and become unspecialised, causing a tumour.
