hope it helps thank you ❤
When two parents are purebred it means that they are homozygous for the characteristic that's being tested (in this case the fur colour). When they are crossed, the offspring will obligatory be heterozygous, an allele of each type from its parents. So, the trait that comes up will be the dominant trait, while the recessive trait will be hidden.
Answer:
A
Explanation:
If a woman with type AB blood and a man with type A blood have a child, the genotype will be AA and and AB (that is, a combination of the mother and father's gene).
Phenotype refer to the gene that is actually expressed. In this case, A.
In the example above, there are 2 phenotypes of Type A blood. The type A blood phenotype can result from two genotypes of AA and AB.
Answer:
warm temperature
Explanation:
<em>I cannot see the choices in your image. I can only see choice A, which is "soil."</em>
"Abiotic factors" are part of the ecosystem that don't have life. However, they have an<em> impact </em>on the<u> life of the</u><u> biotic factors</u><u> </u><em><u>(living organisms)</u></em><u> in the environment.</u> Examples of abiotic factors are:<em> sunlight, temperature, climate, soil, humidity, wind, etc. </em>
"Boreal forests" are abundant on the Earth's Northern Hemisphere. The climate here is generally cold, which doesn't allow some trees to survive. It is totally opposite to the warm temperature and high humidity that you can feel in the<em> "tropical forests." </em>Such factors allow many plants and animals to survive.
Clearly, the boreal forests lack the "warm temperature" that the tropical forests have.
Answer:
It occurred in the mother and in meiosis II stage
Explanation:
A karyotype shows that a child has Klinefelter syndrome (47,XXY) which involves a male child having an XXY chromosome in which the XX chromosome codes from the mother.
If the child is also color-blind (due to a recessive X-linked allele), despite his parents having normal color vision then the nondisjunction occurred in meiosis II because sister chromatids separate during meiosis II and the non separation is the reason for the Klinefelter syndrome.
