Having a karyotype done is important to detect crucial diseases such as Trisomy 13, Trisomy 21, Klinefelter's Disease, and Turner syndrome.
Answer:
Explanation:
The DNA polymerases are enzymes that create DNA molecules by assembling nucleotides, the building blocks of DNA. These enzymes are essential to DNA replication and usually work in pairs to create two identical DNA strands from one original DNA molecule
Answer:
All of the gametes from a homozygote carry the same version of the gene while those of a heterozygote will differ.
Explanation:
A heterozygous individual carries both dominant and recessive alleles of a gene while a homozygous individual carries two copies of either dominant or recessive alleles of a gene. For example, the genotype TT and tt have two copies of dominant and recessive alleles respectively and are therefore homozygous genotypes. On the other hand, the genotype "Tt" is a heterozygous genotype.
An individual with a homozygous genotype would produce all the gametes having the same allele of the gene. The homozygous genotype "TT" would produce all the gametes with one copy of the "T" allele. An individual with a heterozygous genotype makes two types of gametes. The genotype "Tt" would produce 50% gametes having a "T" allele and rest 50% having a "t" allele. Segregation of alleles during meiosis produces different types of gametes in a heterozygous Individual.
