The children in a family all have blue eyes. The biological parents also have blue eyes. The science that explains these similarities is called?
stem cells
genetic engineering
genetics
genomes
The Correct Answer and Explanation is :
The correct answer is genetics.
Explanation:
Genetics is the branch of biology that studies how traits are inherited from one generation to the next. The traits, such as eye color, are determined by genes, which are segments of DNA. The process through which traits like eye color are passed down from parents to offspring is governed by the inheritance of alleles, which are different forms of a gene.
Eye color, specifically blue eyes, is a recessive trait. This means that in order for a child to have blue eyes, they must inherit two copies of the blue-eye allele, one from each parent. If both parents have blue eyes, they each carry two copies of the blue-eye allele (homozygous recessive). When these alleles are passed to their children, all the children will also inherit two copies of the blue-eye allele and thus have blue eyes.
Genetics explains why children inherit similar traits from their biological parents. The scientific study of how these traits are passed down includes analyzing genes, chromosomes, and inheritance patterns. The underlying genetic mechanisms can involve processes such as the inheritance of dominant and recessive traits, mutations, and genetic recombination during reproduction.
Other options like stem cells refer to undifferentiated cells that can give rise to various cell types, genetic engineering refers to the manipulation of an organism’s genome, and genomes are the complete set of genetic material in an organism. While these are important concepts in biology, they do not specifically explain the inheritance of traits like eye color in the same way that genetics does.
I’ll generate an image to illustrate the concept of genetics and inheritance patterns in eye color.
Here is a simplified diagram illustrating the inheritance of eye color in humans. It shows how the two blue-eyed parents (both homozygous recessive) pass their genetic material to their children, resulting in blue-eyed offspring. This diagram highlights the genetic alleles for dominant and recessive traits.
