Answer:

The two previous horses were heterozygous recessive. They carried the genes for OWLs however the genes were recessive therefore the dominate gene gave it's phenotype. I would tell the horse owner that it would be best to breed using different horses, however breeding with the same horses may still lead to healthy results.

Explanation:

This answer revolves around Mendel and his studies. The parents had the gene coding for the disease however it was "out-shined" by the dominant gene, in this case the healthy gene. Therefore the two parents were healthy. Now according to Mendel's research and his punnet square (I suggest you look into it for further explanation) if two heterozygous recessive creatures were to have an offspring there is a high chance that one of their offspring will have the disease seeing as babies in general will receive an allele from the mother and one from the father. So a child having

A couple has three children, two without sickle cell anemia and one with sickle cell anemia. The mother has sickle cell anemia a

bezimeni [28]

Answer:

Explanation:

The sickle cell allele is recessive. Hence, in order for any child of the couple to have sickle cell anemia, such a child will have to inherit an affected allele each from the two parents. This means that both the father and the mother must have affected alleles in their genotypes. In other words, two sickle cell alleles are required for the abnormality to manifest.

Let us assume that the sickle cell allele is represented by S and the normal allele is represented by A.

Now, it is established that the mother has sickle cell anemia, her genotype would be SS. The father does not have sickle cell, his genotype can either be AA or AS.

Assuming the genotype of the father is AA:

SS x AA

AS AS AS AS

All the children would be normal in this case.

Assuming that the genotype of the father is AS

SS x AS

AS SS AS SS

50% of the children would have sickle cell while the remaining 50% would be normal.

Therefore, in order to produce children with sickle cell, the father has to be AS, otherwise, he has to be AA.

What do flowers and runners have in common? how are they different?

kompoz [17]

Answer:

Both flowers and runners help a plant to reproduce.

Explanation:

Both flowers and runners help a plant to reproduce. While a flower help in sexual reproduction, a runner helps in asexual reproduction.

A flower has both male and female gamete at one place. When the pollen grains with in a flower reaches the female ovary, a new seed is produced which has the potential to develop into new plant. In case of runner (which is a stem), the tip of the stem has the potential to grow into a new plant
