Black fur in mice (
Tpy6a [65]
The answer is D) 1/2.

Let's imagine that two genes of the genotype can be analysed separately.

Black fur is determined by dominant allele B. In this case, parents Bb and BB will give offspring with only brown fur:
Parents:          Bb     x     BB 
Offspring:     BB   BB   Bb   Bb
Both homozygous (BB) and heterozygous (Bb) offspring will have black fur.

On the other hand, long tails are determined by recessive allele t. Parents Tt and tt will have 50% offspring with short tail and 50% offspring with long tail:
Parents:         Tt         x       tt
Offspring:    Tt      Tt        tt      tt
Heterozygous offspring (Tt) will have short tail, and homozygous offspring (tt) will have a long tail.

So, the offspring will definitely have black fur and will not affect the fraction of the offspring with black fur and long tails from the cross of <span>BbTt × BBtt. But, </span>there will be 2 out of 4 offspring with short tails which is 50% or 1/2.

Margaret [11]

Answer:

The correct option is A. Algae

Explanation:

Algae is the best possible answer because the process of photosynthesis can be carried out only by plants, algae and cyanobacteria.  Hence, option A is correct. These organisms are called autotrophs as they are capable of making their own food.

Other organisms like paramecium, arthropods and fungi are not capable of photosynthesis. These organisms like arthropods are called heterotrophs. They do not make their own food and feed on other organisms for food.
