In horses, black color (B) is dominant over chestnut color (b). Find the genotype and phenotype ratios of a cross between a hybr
valentina_108 [34]

Answer:

Phenotype: 2:2 or 1:1 / Genotype: 2:2 or 1:1 / 50% probability for chestnut color

Explanation:

If we put the two horses' genotypes in a Punnett square:

         <u> B          b</u>

<u>b</u>        Bb        bb

<u>b</u>        Bb        bb

The phenotype is describing the ending color of the offspring, where 2 of the 4 will be brown (Bb) and 2 of the 4 will be chestnut (bb), resulting in a 2:2 ratio. Genotype only refers to the alleles, where 2 of the 4 will be hybrid (Bb) and 2 of the 4 will be homozygous recessive (bb), again resulting in a 2:2 ratio. There is only a 50% chance that the offspring's phenotype will be chestnut color (bb) because the chestnut allele is recessive.

Which is not a result of increased flexibility

Increased flexibility tend to be achieved by implementing stretching exercise. When we stretch, we would improve our blood circulation because the movement help the blood to flow in different type of direction. In the long run, exercises to increase flexibility would have positive benefit for our cardiovascular system.
