Most people afflicted with recessive disorder with recessive disorders are born to parents who are not affected at all by the disease. Most genetic disorders of humans are caused by recessive alleles. Dominant alleles on the hand cause lethal disorders, however they are less common compared to the recessive alleles disorders, this is because most individuals carrying a lethal dominant allele have the disorder and they die before pass it to the offspring, while the individuals with the recessive lethal genes are more likely to be healthy and reproduce.
Answer:
They are all Eukaryotes, with nucleus, and chromosomes. They also have membrane which demarcate part of the cytosol. In addition they lac cell wall.
Explanation:
<span>a.) Ozone depletion
b.) habitat fragmentation
c.) decreased biodiversity
d.) fossil fuel consumption
So answer choices a, b, and c are all <em>results</em> of nonrenewable sources, but an actual example would be fossil fuel consumption or d,), as the fossil fuels are the source and they cannot be reused :)</span>
The genetic base of the shape of orchid is very complex.
Mendelian traits are described as simple traits determined by one gene. The different alleles of the gene contribute to the difference in the trait. This is true for some traits in plants, animals including humans and other organisms, but not for the shape of orchids.
The shape of orchid flowers is determined by the ABCDE group of genes that are responsible for the body plan in plants. These genes are the equivalent of HOX genes of animals.
The protein products of different genes of the ABCDE group interact with each other in complex ways creating different shapes of orchids.
