A scientist has discovered a new gene in oysters. Oysters with the dominant allele for disease resistance 'R' have been found to

The right answer is B) homozygous dominant

We speak of homo / heterozygosity about a locus, that can be represented by several alleles (version). The alleles are dominant or recessive between them.

*So homozygote: same alleles

*heterozygote: different alleles


Consider a locus and 2 alleles:

allele R: dominant

allele r: recessively


*heterozygote: R / r

*homozygous recessive: r / r

*homozygous dominant: R / R

You cross two red griffins with blue eyes and produce offspring that are: red with blue eyes, red with green eyes, white with bl
sergejj [24]

Answer:

The reason for the offspring to present these genotypes is that during the formation of the gametes, the alleles separate and are inherited independently, therefore they can generate several different phenotypic combinations.

Explanation:

In order for an offspring to present very different phenotypes, as shown in the question above, it is necessary that the two red griffins with blue eyes that were crossed are heterozygous. Thus it will be possible for the offspring to present a wide variety of phenotype, according to Mendel's second law.

Mendel's second law is called the Law of segregation. This law explains that the alleles (which determine the characteristics of individuals) are separated in the formation of gametes and inherited by the offspring of a cross independently, and can generate different combinations of phenotypes, when the parents of a cross are heterozygous.

What molecules are made during transcription
Softa [21]

Answer:

During transcription, only one strand of DNA is usually copied. This is called the template strand, and the RNA molecules produced are single-stranded messenger RNAs (mRNAs). The DNA strand that would correspond to the mRNA is called the coding or sense strand
