Answer: A  the chromosomes from another parent cell were introduced

Explanation: A child is created when the male sex cell joins the female cell. If the male and female sex cells had the standard number of chromosomes, as is found in body cells then the zygote (baby) would have double that number of chromosomes. The number of chromosomes would keep doubling every generation. To avoid this doubling the parent's body cells split by miosis which halves the number of chromosomes and so when the sex cells join the total number of chromosomes is the same as that found in the parent's body cells.

vitfil [10]

Answer:

The correct answer is:

which of the blood type forms when an individual receives one copy of each allele? (D)

Explanation:

Alleles are each of the alternative forms of a gene. In this example, the two forms of the alleles for the Rhesus (Rh) factor are Rh+ and Rh-. These alleles can either be expressed as h0m0zygous alleles (two of the same kind; Rh+ Rh+, Rh- Rh-) or heterozygous alleles (a pair made up of both; Rh+ Rh-)

In the h0m0zygous state, there is the expression of the allele that makes up the pair. However, in the heterozygous state, the dominant allele is expressed phenotypically, even in the presence of the recessive allele that makes up the genotype. Therefore, the dominant allele is the resulting blood group seen in an individual in a heterozygous (one copy of each) state.
