A couple without an ancestral history of Tay-Sachs disease (a rare autosomal recessive) have two normal children and an infant a

Bas_tet [7]

Answer:

The probability is 25%.

Explanation:

Let the dominant allele for the disease be 'T' and recessive allele be 't'.

The couple with normal phenotype produces an infant with the Tay Sach's disease.
As the disease is autosomal recessive in nature, it will get expressed in a homozygous recessive condition, that is, when the genotype is : tt.
As the normal parents are producing a diseased offspring, the both parents must be heterozygous dominant (Tt) for the disease allele.
The brother of the husband and the sister of the wife, both having a normal phenotype, can have the following genotypes, TT or Tt.
If either of the individual (brother or sister) has TT genotype and the other has other has either TT or Tt genotype, there is zero probability that they will produce an offspring with the disease.

T T and T T

If both the individuals have a Tt genotype, the probability to produce diseased offspring is one-fourth or 25%.

If we examine the diagrams of mitosis and meiosis, we see that in both cases, DNA replication occurs. Yet one process

Ymorist [56]

Answer: B Meiosis is followed by fertilization: the union of gametes to create a diploid zygote.

Explanation: Fertilization does enhance genetic variation, but not of daughter cells. It enhances genetic variation in offspring. That means two parents could have four children with a variety of traits, such as different eye color or different heights. Meiosis enhances genetic variation through the reduction of chromosomes number, crossing over, and independent and random assortment of chromosomes.
