I believe the answer would be B.
Answer:
The correct answer is -
Genotypes: 1 heterozygous dominant: 1 recessive
Phenotypes: 1 long hair cat: 1 short hair cat
probability: 50% chances of both long and short hair cats
Explanation:
It is given that long hair is a dominant represented by H, over the short hair represented by h. In the cross of a heterozygous cat for long hair with a cat with short hair, would produce H, h and h, h gametes respectively.
Cross: Hh × hh
H h
h Hh hh
h Hh hh
In this Punnett, there are two heterozygous long hair offspring produced and two short-hair cats.
So, Genotypes: 1 heterozygous dominant: 1 recessive
Phenotypes: 1 long hair cat: 1 short hair cat
probability: 50% chances of both long and short hair cats
I believe true because the Precambrian is the first geologic time, going back 4600-570 years ago, meaning it should contain the earliest of things.
Answer:
Phase of the cell cycle in which cells grow, duplicate organelles, and synthesize DNA.
S phase
Explanation:
DNA replication occurs in synthesis or in the S phase of the cell cycle. Each chromosome is copied with high fidelity in a process that involves a large number of enzymes. In this process the double strand of DNA breaks down and each individual strand is used as a template for the production of the complementary one. The result is the production of two identical copies of the genetic material.
Researchers selected candidate genes by identifying homozygous tracts shared by all three siblings along with the parental phenotype, this type of study is applied for the inheritance of recessive genes. Since the recessive genes can not be expressed in heterozygous genotype, the back tracking of carriers and homozygous recessive individual will help understand its inheritance pattern. The inheritance of dyt2 can be autosomal recessive. It is usually passed on to progeny of two carriers.
