Answer:
The one who determines the gender of a new baby is the father, since he is the carrier of the X and Y sex chromosomes.
Explanation:
The sex chromosomes X and Y are called sex determinants, since the sex of the offspring depends on them:
- <em>XX</em><em> corresponds to the female sex.
</em>
- <em>XY</em><em> corresponds to the male sex.
</em>
A mother can only provide her offspring with X chromosomes, while the father can provide both X and Y chromosomes, so he is the one who determines the sex of a new child. In this case, the possibility of having a male or female child will always be 50:50
Answer:
genotype is responsible for establishing phenotype
Explanation:
When Mendel experimented with pea plants, concept of genes and alleles had not come up yet. Through his experiments Mendel first proved that some type of combination in cells leads to a particular phenotype.
He coined the term "factors" which are today known as alleles. These factors paired up and displayed a particular phenotype. Today we know that the alleles are responsible for a genotype which ultimately results in a phenotype. Hence, he established that genotype is responsible for establishing phenotype even before the term genotype was coined.
