Answer:
Darkened shapes are recessive
Explanation:
In the pedigree shown, we can see that 2 parents that are unshaded shapes have 2 children that are shaded shapes. This would be impossible if shaded shapes were dominant and unshaded shapes were recessive. This is because parents that have a recessive trait have 2 of the same alleles. So if 2 parents that both have a recessive trait have a child, the child will definitely have that trait. But we can see that this is not the case, the parents have 2 offspring that have different phenotype from the parents. This must mean the parents are heterozygous, meaning that they both have 2 alleles that are different. The dominant allele masks the recessive allele, so the dominant allele is expressed. In this case, the children inherited 2 recessive alleles, 1 from each parent, making them have a different phenotype from the parents.
Charles Darwin also was the first biologist to propose the use of the phylogenetic tree or the evolutionary tree. The phylogenetic tree illustrates how organisms are related, usually by traits. It also represents how organisms are related by common ancestors. Other scientists refer to the phylogenetic tree or parts of the tree as a cladogram.
Attached is an example of a simplified phylogenetic tree.
Answer:
Its based on their physical properties
Explanation:
Answer:
The answer would be D. Tropical Rain forests comprise only 6% of all land on Earth yet are home to nearly 50% of all the species on Earth.
