Is balding a recessive gene
WebGregor Mendel's principles of heredity, observed through patterns of inheritance in pea plants, form the basis of modern genetics. Mendel proposed that traits were specified by "heritable elements" called genes. Genes come in different versions, or alleles, with dominant alleles being expressed over recessive alleles. WebAfter this activity, you should be able to understand how DNA determines your appearance. Remember DNA is condensed into chromosomes. You have 23 pairs of chromosomes, 23 from your mother and 23 from your father. Within these chromosomes, there are sections called genes that control specific characteristics or traits.

Mix each allele of one parent with the alleles of the other. For example, if both parents are heterozygous, the Punnett square will look like this: ♂️\♀️. A. WebGene ‘B’ behaves as a dominant in males and as a recessive in females, appearing to exert its effect in the heterozygous state only in the presence of male hormone.
