Red-green color blindness is an X-linked recessive disorder that is passed through generations and can be traced by using a pedi
Nostrana [21]

Answer:

Lisa and Monica

Explanation:

<em>The correct answer would be Lisa and Monica.</em>

<u>For X-linked recessive disorders, a female can be unaffected, a carrier, or affected. However, a male can either be affected or unaffected and never a carrier. This is because females have two X chromosomes while males have only one.</u>

In addition, completely filled-in shapes in a pedigree mean that such individuals are affected for the trait in question while half-filled shapes mean the individuals are carriers for the trait.

Hence, individuals in the pedigree that are labeled carriers for red-green color blindness are Lisa and Monica (they both have half-filled shapes).

nasty-shy [4]
It can be concluded that the cells CONTAIN ACID FAST BACTERIA.
Acid fast staining is a staining technique that is used to differentiate two types of gram positive cells, those that have waxy mycolic acid in their cell wall and those that do not. 
Those cells that do not have mycolic acid in their cell wall will show blue color after acid fast staining.<span />

The dominant allele is D and causes dimples and the recessive allele is d and causes no dimples. How would a geneticist describe
SSSSS [86.1K]

A geneticist describes the phenotype of an individual with the alleles dd as homo-zygous recessive. In heterozygous individuals, it is masked by the dominant allele.

<h3>Dominant and recessive alleles</h3>

In diploid organisms, an individual receives two gene forms or 'alleles' for the same gene locus.

An individual is heterozygous when receives two different alleles for the same gene locus, whereas an individual is homo-zygous when receives the same alleles for a gene locus.

In cases of complete dominance, the dominant allele completely masks the recessive allele in heterozygous individuals.
