Identical twins are produced from the same sperm and egg (which splits after the first mitotic division), whereas fraternal twin

s are produced from separate sperm and separate egg cells. If two parents, one with brown eyes (a dominant trait) and the other with blue eyes (the recessive trait) produce one twin boy with blue eyes, what is the probability that a fraternal twin will transmit the blue eye allele to his or her offspring

Answer:

This is 25%

Explanation:

Analysis, Since the dominant brown eyed  parents  produce blue eye child, this shows they are heterozygote dominant

However,this fraternal twin is not genetically identical, due to the blue eye color,(recessive) but the fact remain that they  are the parents.(because he inherited the recessive allele from each of the parent)Therefore the probability is 25%.

This is because he is the only one out of the 4 kids( based on Mendelian fashion) this is  1/4,25%

Which characteristics do birds and mammals share? Check all that apply.
valkas [14]

Answer:

B and E

Explanation:

The correct answer would be that <u>both birds and mammals are vertebrates and are also endothermic.</u>

Both birds and mammals belong to the same animal kingdom. They also belong to the same chordate phylum but belongs to different classes under the phylum. However, they both belong to the same sub-phylum Vertebrata - a group of chordates with the vertebral column.

Birds (aves) and mammals represent different classes of animals. Birds lay eggs that later hatch when conditions are right to give rise to their young ones. Mammals, on the other hand, give birth to their younger ones and are able to produce milk through their mammary gland to feed them. The body of mammals is characterized by the presence of hairs that help insulate the body making them to be homoiothermic, unlike birds that of birds, where hair is replaced with feathers.

However, both birds and mammals are endothermic, that is, they both maintain a fairly constant body temperature irrespective of the temperature of their environment.

The correct options are B and E.

In many tropical rainforests, people clear land by cutting down trees and burning them. After a few years, the soil runs out of
meriva

Answer:

Land will convert into desert eventually

Explanation:

When the soil gets devoid of nutrient, it will be unable to support trees, plants or vegetation of any type. Trees and plants are responsible for holding the soil tightly and prevent it from eroding.

Once there will be no nutrient in soil, there will be no trees, plants or vegetation and hence there will be no mechanism to prevent soil erosion. Thus, the soil will erode due to deforestation and the land will convert into desert eventually
