Flower position, stem length, and seed shape are three characters that Mendel studied. Each is controlled by an independently as

tresset_1 [31]

Answer:

1/64

Explanation:

<em>The probability of the offspring being homozygous dominant for the three alleles is 1/64.</em>

Since the three characters assort independently, the probability of the offspring being homozygous dominant for all the three traits is an independent event.

For independent events, the probability of all the events happening together is the multiplication of individual event's probability.

For a cross involving two heterozygotes, taking tall/dwarf for example:

Tt x Tt = TT, 2Tt, tt

The probability of obtaining a homozygous dominant genotype is 1/4.

Hence, the probability of the offspring being homozygous dominant for the three alleles will be:

1/4 x 1/4 x 1/4 = 1/64

Which of the following statements is true about Tiktaalik?

yawa3891 [41]

Tiktaalik is a transitional fossil which shows how fish evolved into amphibians and reptiles. So the correct option is B.

What is Tiktaalik?

Tiktaalik is a direct ancestor of tetrapods or four-legged animals. It is an extinct fish-like animal and it lived on earth 380-385 million years ago (Devonian period).

The word Tiktaalik is derived from the <em>Inuktitut</em> language which loosely translates to large freshwater fish. This animal had characteristics of both fish and tetrapod and is therefore called the link between these two kinds of animals.

The characters resembling fish are gills and scales and the characters resembling tetrapods are rib bones, movable neck and lungs. There are characters that are a mix of both tetrapods and fish. These are bones and joints in limbs but fish-like fins instead of feet or hands.
