Answer;
Mitochondria and chloroplasts contain their own DNA.
Explanation;
-Mitochondria and chloroplasts have striking similarities to bacteria cells. They have their own DNA, which is separate from the DNA found in the nucleus of the cell.
-From the Endosymbiotic theory, even though both organelles are found in eukaryotic cells, both mitochondria and chloroplast have characteristics often found in prokaryotic cells. These prokaryotic cell characteristics include: an enclosed double membrane, circular DNA, and bacteria-like ribosomes.
Answer: His phenotype will be Bb. He will have brown hair because it is a dominant trait.
Explanation: Heterozygous indicates that there are two different genes present in a genotype (Bb instead of BB or bb).
Each parent contributes one allele describes the influence that parents have on whether or not offspring inherit a genetically inherited trait.
Explanation:
Allele is a form of gene present on the chromosome. Human have 2 alleles for a trait on a chromosome. Each parent contributes one of its allele to the progeny.The alleles for the gene are present on the same locus of chromosomes.
The alleles are either dominant or recessive. The contribution of alleles and the expression of trait decide the alleles of offspring.
The phenotype is determined by the allele expressed as short or tall and human ABO blood type.
An allele is sequence of DNA. The organism having two same alleles are homozygous and having two different alleles are heterozygous.
