50 percent of the offspring would be expected to have the ability to roll their tongues If a heterozygous male is crossed with a homozygous recessive female.
Explanation:
Information given:
the ability to roll tongue is dominant, the genotype would be RR, Rr
the inability to roll tongue is recessive trait the genotype = rr
Given that heterozygous male is crossed with homozygous recessive female, the genotype is
Rr X rr
Punnet square shows that:
R r
r Rr rr
r Rr rr The genotype ratio is 1:1
phenotype ratio is 1:1
There are chances of 50 % offspring having the ability to roll their tongues as they are heterozygous and have the dominant allele for rolling of tongues.
Answer:
II
Explanation:
Since 'I' is the more dominant trait and 'homozygous dominate' is asking for the same dominante feature, II should be the answer

Earth's history. In the worst one, 250 million years ago, 96 percent of marine species and 70 percent of land species died off. It took millions of years to recover.
Answer:
I think Eukaryotic, and Stationary goes to the Elodea cell, and the other two goes to the other one
Answer:
The correct answer is-Wernicke's area.
Explanation:
Wernicke's area is located on the left side of the brain in the temporal lobe. It is that region of the brain which is responsible for language development and language comprehension.
So if a problem occurs in the Wernicke's area of the brain than it will be difficult for that person to form a meaningful speech and understanding the words being spoken to them. That person will be able to talk fluently and in phrases but his sentences might lack meaning.
Therefore the damage to Gia's brain was probably localized in her Wernicke's area.
