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.
Lll. a limited supply of necessary resources. If there isn't enough resources the species will have to learn to adapt to be able to gather the new food supply they need. Such as birds and there beaks, if the insects population went down and that was the main food supply for that type of bird they would have to be able to adapt in order to survive, so evolution occurs. Over time that bird would change to adapt to its new feeding source.
Hope this helps!
The answer would be: relatively constant environmental conditions
When the environment condition is changed, the organism need to changes too. If the organism reproduced asexually, their genetic material of the offspring would be identical without change. This makes asexual reproduction couldn't produce a different offspring.
Sexual production will produce a various genetic material that might turn the changes into beneficial condition.
