Answer:
B and D
Explanation:
Since it says all carbon atoms have six electrons, we know that they only have six protons too. The carbon 13 and 14 means they have extra neutrons that increases their atomic mass.
Answer:
carbon source Earth's crust
Cross pollination is the transfer of pollen of different species to stigma of different species of plants.
Cross pollination results in healthy, viable and diverse plants.
Mendel observed that traits could either be dominant or recessive.
Blended traits or incomplete dominance is the condition in which dominant allele could not produce its trait alone instead blending with recessive allele takes place giving new phenotype to progeny.
Explanation:
In cross pollination pollen transfer takes place from anthers to stigma. In Mendelian genetics the anthers of the plant was removed because it has both male and female parts on same plant so that self pollination does not take place.
The importance of cross pollination is that it creates diversity in the plant species since the traits having different alleles are combined to form the progeny plant. The offspring are healthier and high quality seeds are found.
Mendel observed that traits are either dominant or recessive in general. It was observed that when homozygous parents were crossed, the progeny in F1 generation always had dominant trait. The recessive trait only appeared when F1 generation offspring were self pollinate.
Blended traits or incomplete dominance appear when alleles get blended and exhibit the traits in phenotype. The phenotype appeared will not be matching with either parents.
The example is a white coloured flower is crossed with red colour flower the resultant colour of the flower is pink. It shows that dominant allele red is not completely dominant and gets blended with white colour.
Answer:
carbon and titanium, hope that helps
Explanation:
The allele for dwarfism - D its dominant
Recessive allele -d
If the person has heterozygous alleles -Dd the person will have achrondroplastic dwarfism
However if the person if homozygous for the allele DD it’s Lethal and person can’t survive
If both parents are Dd
Dd X. Dd
Offspring DD Dd Dd dd
Probability of children who survive with the trait have the genotype Dd
Probability - 1/4 + 1/4
Probability of having surviving children with the trait -1/2 -0.5
