Answer:

For an offspring to have a recessive trait, both parents must have at least one recessive allele in their genotype

Explanation:

When an organism contains a pair of dissimilar alleles for a given trait it is said to be heterozygous. A heterozygous state contains one dominant allele and a recessive allele. When two parents are heterozygous, the offspring will have a recessive trait. For example a cross between heterozygous tall plants.

In rabbits, short hair (S) is dominant over long hair (s). What genotype and phenotype ratios are expected from a cross between

irga5000 [103]

Answer:

Answer:

Genotype Phenotype

SS 1/4 Short hair 3/4

Ss 2/4 Short hair 3/4

ss 1/4 Long hair 1/4

Explanation:

Both are heterozygous for the trait so we can expect that the cross would be:

Ss x Ss

S s

S SS Ss

s Ss ss

So the resulting off-spring would have the following genotype and phenotype:

1 out of 4 will have a genotype of SS.

2 out of 4 or half will have a genotype of Ss.

1 out of 4 will have a genotype of ss.

But because short hair is dominant the phenotype ratios would differ because Ss and SS would express short hair, so we add up their ration:

Short hair: 1/4 + 2/4 = 3/4

Long hair: 1/4

So in summary:

Genotype Phenotype

SS 1/4 Short hair 3/4

Ss 2/4 Short hair

ss 1/4 Long hair 1/4

Which stament describes what happend to elements during radioactive decay?

maw [93]

In alpha decay, the nucleus loses two protons. In beta decay, the nucleus either loses a proton or gains a proton. In gamma decay, no change in proton number occurs, so the atom does not become a different element. ... If it loses two protons through alpha decay, it will have 82 protons

The x-ray film shows a fracture where one side of the cortex is intact and flexed and the other side has signs of interruption (

zalisa [80]

Answer:

The correct answer is - option B.

Explanation:

Greenstick fractures are the type of fractures where one side of the cortex is intact and flexed while the other side is fractured. This type of fracture known as the incomplete fracture,

If any fracture have two or more lines of fracture it is called as Comminuted fractures. Impacted fractures have one segment on other. Due to the performing same activity again and again stress fracture occures that is characterized by failure of one cortical bone.

Thus, the correct answer is option B.
