The snow goose (chen caerulescens) has both a blue and a white morph. inheritance is mendelian: bb and bb individuals are blue,

while bb individuals are white. if 23 geese in a population of 142 are white, and 119 are blue, how many of the blue geese would you expect to be carriers of the b allele (i.e., bb heterozygotes)

We solve the problem using the Hardy-Wineberg equation.

Let us start with the homozygous recessive number of white trait,

∴ q² =  \frac{23}{142} = 0.16

We have the frequency for white trait as q = 0.4

Solving for the frequency of blue trait by using the fact that,

p + q = 1

∴ p = 1 - q = 1 - 0.4 = 0.6

Now we can calculate 2pq in p² + 2pq + q², which is the frequency for heterozygous blue trait,

∴ 2pq = 2 x 0.6 x 0.4 = 0.48

And the homozygous blue trait is given by the expression,

∴ p² = 0.6² = 0.36

Hence, the carriers for the trait of blue are, 0.48 + 0.36 = 0.84, or 84% of 142.

∴ 84% of 142 = \frac{84 \times 142}{100} = 119

Answer is 119.

The sporophyte of an unknown plant species grows as a separate plant than the gametophyte. The plant produces both female and fl
N76 [4]

Answer:

The correct answer would be "The plant is a fern, and sporophyte is its dominant phase".

Ferns refer to the lower plants which do not bear flowers, have leafy or feathery fronds, and they reproduce by spores.

They show alternation of generation in which sporophyte is the dominant stage.

The mature diploid sporophyte releases haploid spores with the help of meiotic divisions.

The haploid spore divides by mitotic division and matures into a haploid gametophyte. The single gametophyte bears antheridium and archegonium which release flagellated male gametes and egg (female gamete) respectively with the help of mitotic division.

The gametes fertilize to produce a diploid zygote.

The zygote divides mitotically and matures into the diploid sporophyte.

What is the name given to organisms that can make their own food for the biosphere?
Ray Of Light [21]
Autotrophs are organisms that can make their own food for the biosphere.

This term comes from the Greek terms:
Auto- meaning "self" and Troph- meaning "feeding or growth"
So autotroph quite literally means "to feed oneself". Autotrophs, for the most part, use photosynthesis from sunlight to produce their own sugars.
Plants are the primary autotrophs on Earth!
