The phenotype of the F1 generation offsprings will be black. They will be heterozygous in nature.
<h3><u>Explanation:</u></h3>
The genes for the fur colour in horses are completely dominant and the dominant colour is black and is represented by B. The recessive colour is chestnut and is represented by t.
The genotype of the homozygous black horse is BB. and the genotype of the homozygous chestnut coloured parent is tt.
The gametes from the black parent =B.
The gametes from the chestnut parent = t.
So the genotype of the F1 offspring = Bt.
It is a heterozygous black horse because the black gene is completely dominant over chestnut gene.
The answer is <span>D.A mouse lies still when it sees a cat, which helps it evade detection by a predator.
Behavioral adaptations are thing organisms do to increase their chance to survive and reproduce. This is, actually, how organisms react in response to a threat. For example, animals could move from place to place, or imitate something they are not (mimicry). The example of mouse's behavioral adaptation is when mouse sees a cat, it lies still in order to evade it. Mouse changes its behavior to survive.</span>
An object's speed in a particular direction is called its velocity.
Answer:
This is true, because the advent of genetic engineering and different nutritional researches have greatly enhanced the Nutritional values in foods, with resultant increases in the growth and development of cells and tissues from increase growth hormones metabolism. However, reduction in the outbreak of disease, due to advancement in medical research and drug manufacturing are another factors which may contribute to this
