1. Name three types of evidence used to support the theory of evolution
Llana [10]

Answer:

1) Fossil evidence Support

2)Genetic evidence supports evolution.

Biological evidence supports evolution;

Explanations;

1)Fossil evidence Support evidence;

This gives the geographic information about many fossils, it gives evidence that two species with a common ancestor can have their development differently and in

different locations. The common ancestor term is crucial especially in

theory of natural selection . In this evidence there is prove that common ancestor is shared through comparison between modern plants and modern algae to fossil algae by scientist.

Examples are bones, exoskeletons, stone imprints of microbes as well as animals.

2)Genetic evidence supports evolution.

This provides the understanding of how traits are passed from one generation to another under the study of DNA, DNA which contains the information needed by all organisms need to grow and to maintain themselves.geneticmaterial are passed to offspring by parent during reproduction. There are code which is made up of different chemical sub unit known as base. posses by DNA that helps to to function properly.

represented by letter A, T, C, and G.

3)Biological evidence supports evolution;

In this evidence, details about how evolution can be observed within the physical structures of adult organisms. is provided. It is evidence that involves of structural evidence such as vestigial structure which means an organisms with organs and similar structures with different functions.

For Example, considering the bodies of whales which is an organisms,there are small leg bones that are vestigial.

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.
