In humans, blue eyes are caused by a recessive allele ("b") that dilutes pigment production. BB and Bb individuals have brown ey
saveliy_v [14]

Answer:

Probability that the son will be:

color-blind = 1/2

blue eyed = 1/8

blue eyed and color-blind = 1/16

Explanation:

Mother : BbXcX

Father : BbXY

Colorblindness is X linked recessive trait hence will be caused when the son has XcY genotype.

XcX   X    XY :

     Xc    X

X  XcX  XX

Y   XcY  XY

Half of the sons will have normal vision and other half will be colorblind hence, there is 1/2 probability that the son will be colorblind.

Eye color is autosomal trait and blue color will be produced when the child has bb genotype.

Bb     X    Bb  :

   B    b

B  BB  Bb

b  Bb   bb

1/4 of the children will have blue eyes. Since half of the children are expected to be males, 1/4 * 1/2 = 1/8 sons are expected to have blue eyes.

Probability of a son being blue eyed and color blind will be :

1/8 * 1/2 = 1/16

What is meant by ‘fishing down the food web’?
stepan [7]

Answer:

Fishing down the food web is the process whereby fisheries in a given ecosystem, "having depleted the large predatory fish on top of the food web, turn to increasingly smaller species, finally ending up with previously spurned small fish and invertebrates".

When the nucleus of a fully differentiated carrot cell is injected into a frog egg whose nucleus has been removed, the injected
Alexxandr [17]

In this case, it is given that the nucleus of the carrot cell is injected into the frog's egg lacking nucleus. In this case, the recipient egg (frog egg) would not be able to produce the carrot. Every species differ from from each other, sometimes, mating between closely related species can produce hybrid offspring, but frog and carrot cannot be combined at all in any aspect.

The carrot is a plant and the frog is an animal. All the physiological processes vary a lot in between plant and the animal. Hence, this growth would not be supported. So, it is impossible to generate a carrot by inserting it's nucleus in the frog's cell.

All of the following except __________ developed in some vascular plants and are not present in any nonvascular plants.All of th
dem82 [27]

Answer:

Vascular plants have separate tubular tissues such as xylem, phloem for smooth transport of water, minerals and food while non-vascular plants do not show these attributes.

Explanation:

Although both life cycles are divided between the sporophytic and gametophytic generations, vascular plants have a dominant diploid sporophytic phase while non-vascular plants have a dominant haploid gametophytic phase.

Non-vascular plants are poikilohydric (they can withstand dehydration and can recover without any damage to their tissues), though they cannot control the water level in their cells and tissues. On the other hand, vascular plants are homoiohydry. They can survive in any habitat and can control the water content in cells and tissues, though they have low capacity to survive dessication compared to the non-vascular plants.

Non-vascular plants do not have true leaf. The leaves are mere chlorophyll containing. Photosynthesized food are directly sent from one cell to the other. They lack proper transport mechanism for food and water.

On the other hand, the vascular plants have complex multilayered leaf (cells) structure. The waxy layer cuticles on the leaves prevent dessication. That are more chlorophyll containing than their counterpart.
