<span>When the idea of evolution originated, scientists used objects that were similar. An example being given would be that of monkeys and humans were much more alike than dogs and monkeys. When scientists realized how minor those differences were, it enabled them to study how close those relationships actually were. Public knowledge grew about cells and DNA; scientists also knew how it could be used to determine similarities and differences in proteins in humans and animals. Tying all of these methods together will create an evolutionary map.</span>

Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offsprin
Andrei [34K]

Answer:

The correct answer would be 2 in 4.

According to the question Xo and XO show codominance and express themselves completely when present in heterozygous condition. Cats bearing XoXO show patchwork of black and orange fur and are called tortoiseshell cats.

Xo codes for orange color fur and XO codes for black color fur. In addition, Y chromosome does not contain any gene associated with fur color.

Now, genotype of mother cat is XOXO (orange fur). So, the gametes formed would be XO only.

The genotype of father cat is XoY(black fur). So, the gametes would be Xo and Y.

The cross would lead to the formation of two male cats each having XOY as their genotype and two female cats each with XOXo as their genotype.

Hence, both the male cats would show orange fur and both the female cats would show patchwork of orange and black fur.

Therefore, we can conclude that 2 out of 4 would exhibit tortoiseshell coloring.

1. How did you revise your sequence from your initial idea ? Explain how you decided on the sequence. For the Natural Selection
liberstina [14]

Natural selection is the idea that  organisms that posses favorable traits that enable them to survive in their environment are the ones that live long enough to pass on these traits to their offspring.

<h3>What is natural selection?</h3>

The question is incomplete but I will try my best to explain the idea of natural selection.

The term natural selection refers to the idea put forward by Charles Darwin that organisms that posses favorable traits that enable them to survive in their environment are the ones that live long enough to pass on these traits to their offspring. This is also called the survival of the fittest.
